1
00:00:03.880 --> 00:00:05.800
We're good for all of two slides.

2
00:00:05.960 --> 00:00:07.120
My apologies.

3
00:00:09.280 --> 00:00:11.280
So just a quick introduction.

4
00:00:11.400 --> 00:00:12.640
Sorry about that, everyone.

5
00:00:12.760 --> 00:00:16.355
For the macroinvertebrate data mining study ...

6
00:00:16.355 --> 00:00:19.950
introduction prior to Cody's presentation,

7
00:00:19.950 --> 00:00:22.599
a little background on the study.

8
00:00:23.120 --> 00:00:26.814
The study was recommended by the science team to the ...

9
00:00:26.814 --> 00:00:29.821
action team and the stakeholders team as a ...

10
00:00:29.821 --> 00:00:33.773
priority study among a long list of potential Hinkson ...

11
00:00:33.773 --> 00:00:37.639
Creek studies in the 2019 science strategy document.

12
00:00:38.720 --> 00:00:41.525
We'll be having more to say about the science strategy ...

13
00:00:41.525 --> 00:00:42.959
document in a couple weeks.

14
00:00:43.000 --> 00:00:46.900
In the last presentation, the purpose of the study was ...

15
00:00:46.900 --> 00:00:50.713
to analyze stressor metrics from MD and R's existing ...

16
00:00:50.713 --> 00:00:54.093
invertebrate data, of which there are years of ...

17
00:00:54.093 --> 00:00:58.426
data determine if there were additional metrics that could ...

18
00:00:58.426 --> 00:01:02.759
help indicate the sources of impairment to Hinkson Creek.

19
00:01:02.840 --> 00:01:07.102
So it was basically an addition of many other ...

20
00:01:07.102 --> 00:01:12.171
measuring tools to see if we could uncover anything,

21
00:01:12.171 --> 00:01:16.318
any other information from existing data.

22
00:01:17.360 --> 00:01:20.358
The study was funded by the Cam stakeholders,

23
00:01:20.358 --> 00:01:23.119
the city of Columbia, Boone county and the ...

24
00:01:23.119 --> 00:01:26.274
University of Missouri, and the action team put ...

25
00:01:26.274 --> 00:01:29.903
together a proposal for the study and bid it out with the ...

26
00:01:29.903 --> 00:01:31.638
award going to Geosyntec.

27
00:01:31.720 --> 00:01:34.400
So with that, I will stop presenting and ...

28
00:01:34.400 --> 00:01:38.461
hopefully everything will work well and I'll have a few more ...

29
00:01:38.461 --> 00:01:39.679
slides at the end.

30
00:01:41.080 --> 00:01:42.194
Hey, thank you,

31
00:01:42.194 --> 00:01:43.479
Tim. I'm going to.

32
00:01:43.520 --> 00:01:45.960
This is Cody Lubring with Geosyntech.

33
00:01:46.000 --> 00:01:47.400
I'm going to share my screen.

34
00:02:03.840 --> 00:02:06.048
Michele, can you confirm that you can ...

35
00:02:06.048 --> 00:02:07.359
see the presentation?

36
00:02:07.840 --> 00:02:09.000
Yes, I can.

37
00:02:10.200 --> 00:02:11.320
Okay, great.

38
00:02:11.440 --> 00:02:12.600
I appreciate it.

39
00:02:12.720 --> 00:02:13.913
All right, well,

40
00:02:13.913 --> 00:02:17.238
welcome action team, science team members and ...

41
00:02:17.238 --> 00:02:21.245
stakeholders to Hinkson Creek macroinvertebrate data ...

42
00:02:21.245 --> 00:02:22.438
mining project.

43
00:02:23.160 --> 00:02:25.760
As Tim said, I work for Geosyntec.

44
00:02:25.760 --> 00:02:27.000
My name is Cody Lubring.

45
00:02:27.120 --> 00:02:31.691
I've worked with water quality, water quantity,

46
00:02:31.691 --> 00:02:36.039
aquatic ecological data for the past 15 years.

47
00:02:36.200 --> 00:02:38.640
I do have with me doctor Sam McCord.

48
00:02:38.760 --> 00:02:40.840
Would you like to introduce yourself, Sam?

49
00:02:41.040 --> 00:02:43.880
Yeah, I'm Sam McCordan.

50
00:02:43.880 --> 00:02:45.840
I'm an aquatic biologist.

51
00:02:46.000 --> 00:02:50.588
I've been working with this field of study for about 30 ...

52
00:02:50.588 --> 00:02:53.647
years, partly in the private sector ...

53
00:02:53.647 --> 00:02:58.439
and partly for Department of Natural Resources and some ...

54
00:02:58.439 --> 00:03:00.478
of it on Hinkson Creek.

55
00:03:00.520 --> 00:03:05.600
And I was subcontracted to help Geosyntec with the project.

56
00:03:06.280 --> 00:03:07.480
Thank you, Sam.

57
00:03:07.680 --> 00:03:11.672
Sam and I are both intimately familiar with Hinkson Creek ...

58
00:03:11.672 --> 00:03:16.479
and I've spent a lot of time all stretches and reaches of Hinkson Creek.

59
00:03:24.960 --> 00:03:26.926
All right, today's presentation,

60
00:03:26.926 --> 00:03:29.639
we'll start out with a health and safety moment.

61
00:03:29.800 --> 00:03:33.366
We will talk about the data mining project goals and ...

62
00:03:33.366 --> 00:03:35.439
objectives a little bit more.

63
00:03:36.280 --> 00:03:40.656
We'll outline what publicly available data we used,

64
00:03:40.656 --> 00:03:45.131
the methods for assessing the invertebrate metrics,

65
00:03:45.131 --> 00:03:50.004
the methods for evaluating the invertebrate metrics from ...

66
00:03:50.004 --> 00:03:55.175
a statistical perspective, the results of those statistical ...

67
00:03:55.175 --> 00:03:58.158
analyses and metric calculations.

68
00:03:58.600 --> 00:04:03.049
We'll also talk about a winter season data collection effort ...

69
00:04:03.049 --> 00:04:07.062
that we took on as part of the project and using all those ...

70
00:04:07.062 --> 00:04:10.289
information from publicly available data,

71
00:04:10.289 --> 00:04:11.772
metrics, analyses,

72
00:04:11.772 --> 00:04:14.301
and results, provide a summary and ...

73
00:04:14.301 --> 00:04:17.877
recommendation as part of the project to the cam.

74
00:04:22.080 --> 00:04:24.938
So for today's health and safety topic,

75
00:04:24.938 --> 00:04:27.190
we'll talk about slips, trips,

76
00:04:27.190 --> 00:04:30.741
and falls regardless of workplace environment,

77
00:04:30.741 --> 00:04:33.599
whether it's outdoors or in the office.

78
00:04:34.320 --> 00:04:37.363
The Department of Labor attributes slips,

79
00:04:37.363 --> 00:04:39.561
trips, and falls to majority of ...

80
00:04:39.561 --> 00:04:43.450
workplace accidents for us investigators that work in ...

81
00:04:43.450 --> 00:04:46.747
Hinkson Creek or other streams throughout the ...

82
00:04:46.747 --> 00:04:49.452
country, regardless of other outdoor ...

83
00:04:49.452 --> 00:04:52.918
environments, to mitigate slip trips and falls.

84
00:04:53.040 --> 00:04:56.080
Let's maintain situational awareness.

85
00:04:56.480 --> 00:05:00.502
Understand and recognize when things like algae are ...

86
00:05:00.502 --> 00:05:04.159
present that increase potential for slippage.

87
00:05:04.560 --> 00:05:06.654
Understand when surfaces get wet,

88
00:05:06.654 --> 00:05:09.399
they're often slicker than when they're not.

89
00:05:09.720 --> 00:05:13.587
Identify great ingress and egress locations to,

90
00:05:13.587 --> 00:05:16.700
for example, in stream environments it ...

91
00:05:16.700 --> 00:05:20.473
may not be the closest, may have to walk around to ...

92
00:05:20.473 --> 00:05:24.718
access the stream in a safer manner or safer location.

93
00:05:25.120 --> 00:05:29.073
Keeping proper footwear with the caveat noting that if ...

94
00:05:29.073 --> 00:05:31.909
you're working in streams of Missouri,

95
00:05:31.909 --> 00:05:35.003
the Department of Conservation does have a ...

96
00:05:35.003 --> 00:05:38.784
ban on felt sold waders, but keeping proper footwear ...

97
00:05:38.784 --> 00:05:42.823
with good tread traction, utilizing trekking poles or a ...

98
00:05:42.823 --> 00:05:46.862
hiking stick to assist walking over uneven surfaces and ...

99
00:05:46.862 --> 00:05:50.557
then be just reminder when you're walking on uneven ...

100
00:05:50.557 --> 00:05:54.596
surfaces to keep your hands free and available and don't ...

101
00:05:54.596 --> 00:05:58.291
keep them in your pocket when you are walking in case ...

102
00:05:58.291 --> 00:06:00.955
you do fall to help keep your balance.

103
00:06:03.280 --> 00:06:07.445
So the invert data mining project goals and objectives ...

104
00:06:07.445 --> 00:06:11.067
are to compile, analyze and interpret existing ...

105
00:06:11.067 --> 00:06:14.960
macro invertebrate, chemical and physical data to ...

106
00:06:14.960 --> 00:06:19.125
diagnose stressors causing the Hinkson Creek Aquatic ...

107
00:06:19.125 --> 00:06:23.381
Life Impairment project began in July August of 2019 and ...

108
00:06:23.381 --> 00:06:27.637
completed in approximately September October of 2020.

109
00:06:28.040 --> 00:06:32.920
We're now just getting to relay this information to the ...

110
00:06:32.920 --> 00:06:37.163
stakeholders thanks to the Covid-19 pandemic,

111
00:06:37.163 --> 00:06:40.239
but the data used for this project.

112
00:06:40.400 --> 00:06:43.366
As Tim mentioned, there was a host of data ...

113
00:06:43.366 --> 00:06:47.466
collected from 2001 to 2017 by the Department of Natural ...

114
00:06:47.466 --> 00:06:49.646
Resources, and not only are we ...

115
00:06:49.646 --> 00:06:53.833
interested in Hinkson Creek, we are also evaluating data ...

116
00:06:53.833 --> 00:06:57.496
from the nearby control stream of Bonfam Creek and ...

117
00:06:57.496 --> 00:07:01.857
also the ecological drainage unit reference streams which ...

118
00:07:01.857 --> 00:07:04.474
include Manito Creek, Theft Creek,

119
00:07:04.474 --> 00:07:06.916
Ferris Fork, and the Luder river.

120
00:07:07.360 --> 00:07:09.736
You know, in Hinkson Creek,

121
00:07:09.736 --> 00:07:13.559
I have two segments outline urban and rural.

122
00:07:15.000 --> 00:07:19.569
The rural segment of Hinkson Creek is the upstream portion ...

123
00:07:19.569 --> 00:07:23.951
and I want to stop there just for a second and confirm with ...

124
00:07:23.951 --> 00:07:28.333
Michele that you guys can see me transitioning through ...

125
00:07:28.333 --> 00:07:29.638
the slides. Yep.

126
00:07:29.800 --> 00:07:31.440
You're on the projects and goals.

127
00:07:31.560 --> 00:07:34.762
Project goals and objectives slide correct and you can see ...

128
00:07:34.762 --> 00:07:36.199
the map and table correct?

129
00:07:36.280 --> 00:07:38.480
Yes, absolutely.  Thank you.

130
00:07:38.640 --> 00:07:40.720
I just wanted to make sure I wasn't getting ahead of myself.

131
00:07:40.800 --> 00:07:42.160
Yeah, always good to do.

132
00:07:43.600 --> 00:07:49.019
The urban portion of Hinkson Creek relates to MD and R ...

133
00:07:49.019 --> 00:07:51.359
sites one through six.

134
00:07:51.480 --> 00:07:53.658
One being at Scott Boulevard,

135
00:07:53.658 --> 00:07:57.055
two at Twin Lakes, three at Forum Boulevard 3.5 ...

136
00:07:57.055 --> 00:08:00.975
at Recreation Drive or near Providence Road Hinkson ...

137
00:08:00.975 --> 00:08:04.982
Creek four near Rock Quarry Road Hinkson Creek five at ...

138
00:08:04.982 --> 00:08:08.553
Cape and Park and then Hinkson Creek 5.5 at Green ...

139
00:08:08.553 --> 00:08:11.515
Valley Drive, which is also Broadway and ...

140
00:08:11.515 --> 00:08:14.477
then Hinkson Creek six at Walnut street.

141
00:08:14.560 --> 00:08:18.724
So these are the sites within Hinkson Creek designated ...

142
00:08:18.724 --> 00:08:20.319
as the urban portion.

143
00:08:20.640 --> 00:08:24.395
The rural portion of Hinkson Creek includes site 6.5,

144
00:08:24.395 --> 00:08:27.660
which is upstream of the highway 6370 Connector ...

145
00:08:27.660 --> 00:08:31.007
Hinkson Creek seven, which is at Hinkson Creek ...

146
00:08:31.007 --> 00:08:33.292
Road and then Higson Creek eight,

147
00:08:33.292 --> 00:08:36.802
which is at Rogers Road and also known to many people ...

148
00:08:36.802 --> 00:08:38.597
upstream of the landfill.

149
00:08:38.720 --> 00:08:45.228
The city of Columbia the 2001 to 2017 publicly available in ...

150
00:08:45.228 --> 00:08:51.337
DNR data included 172 valid invert community samples,

151
00:08:51.337 --> 00:08:56.118
which are comprised of multiple habitats.

152
00:08:56.480 --> 00:09:00.539
These habitats that comprise one sample include coarse ...

153
00:09:00.539 --> 00:09:03.475
ripple substrate, depositional areas,

154
00:09:03.475 --> 00:09:05.893
and root mat, so they're the three ...

155
00:09:05.893 --> 00:09:10.038
compositions that include one invert community sample.

156
00:09:10.600 --> 00:09:16.010
Of those 172 valid samples, 67 were collected within the ...

157
00:09:16.010 --> 00:09:20.039
fall season of September 15 to October 14.

158
00:09:20.480 --> 00:09:24.160
So we have the Henson Creek Rural Treatment Group.

159
00:09:24.320 --> 00:09:25.760
There were nine samples.

160
00:09:25.880 --> 00:09:30.480
The Hinkson Creek Urban Treatment group there were 40 samples.

161
00:09:30.640 --> 00:09:33.662
Within the Bonfem control treatment group,

162
00:09:33.662 --> 00:09:37.255
there were twelve samples and the reference streams ...

163
00:09:37.255 --> 00:09:40.358
included six samples within the fall period.

164
00:09:40.840 --> 00:09:44.560
The spring period included 105 samples.

165
00:09:45.080 --> 00:09:48.595
The spring period includes a time of March 15 to April 14,

166
00:09:48.595 --> 00:09:52.559
so there are more samples in the spring than what there are fall.

167
00:09:53.480 --> 00:09:56.600
There are 23 from rural Hinkson Creek,

168
00:09:56.600 --> 00:09:59.915
56 from the urban Hinkson Creek portion,

169
00:09:59.915 --> 00:10:04.400
17 from bond film control, and nine from the reference.

170
00:10:05.960 --> 00:10:09.927
The chemical and physical data used to assess the ...

171
00:10:09.927 --> 00:10:14.959
community and differences were water chemistry parameters.

172
00:10:15.040 --> 00:10:17.960
There were quite a few, which we'll talk about a little bit more.

173
00:10:18.440 --> 00:10:20.390
Land use, land cover,

174
00:10:20.390 --> 00:10:25.157
national pollutant discharge elimination system,

175
00:10:25.157 --> 00:10:29.599
outfalls within the watershed, and streamflow.

176
00:10:30.400 --> 00:10:33.254
Through this process of compiling the data and ...

177
00:10:33.254 --> 00:10:35.961
running through the analysis of these data,

178
00:10:35.961 --> 00:10:39.327
there are some limitations that we identified and it's ...

179
00:10:39.327 --> 00:10:43.278
good to let people aware for future data collection activities.

180
00:10:44.240 --> 00:10:49.966
Static or one time data collection are unrelevant to ...

181
00:10:49.966 --> 00:10:52.959
run correlation analyses.

182
00:10:54.400 --> 00:10:58.240
Static or excuse me, sample sizes that are very small.

183
00:10:58.360 --> 00:11:03.310
One or two samples at one or two locations are again are ...

184
00:11:03.310 --> 00:11:07.160
irrelevant to run correlation analyses.

185
00:11:08.880 --> 00:11:11.859
Do know there have been a lot of data collected from ...

186
00:11:11.859 --> 00:11:14.199
different entities on Hinkson Creek.

187
00:11:14.320 --> 00:11:16.150
However, some of the data were ...

188
00:11:16.150 --> 00:11:18.199
unavailable for our assessment.

189
00:11:19.600 --> 00:11:22.664
So again, the rural portion of Hinkson ...

190

From 2001 to 2017, the Department of Natural ...

201
00:12:08.908 --> 00:12:14.599
Resources collected 187 microinvertebrate community samples.

00:12:24.440 --> 00:12:28.223
15 community samples were removed due to various ...

206
00:12:28.223 --> 00:12:30.898
reasons, including catastrophic ...

207
00:12:30.898 --> 00:12:35.511
drought conditions during the fall of 2012 and then several ...

208
00:12:35.511 --> 00:12:39.478
samples within the rural portion of Hinkson Creek.

209
00:12:39.520 --> 00:12:43.042
At site seven, eight were either collected ...

210
00:12:43.042 --> 00:12:47.542
during no flow conditions, so not all the habitats were ...

211
00:12:47.542 --> 00:12:50.575
available, or several of the samples ...

212
00:12:50.575 --> 00:12:53.118
were missing root mat habitat.

213
00:12:53.280 --> 00:12:56.962
So if not all three habitats were collected in a ...

214
00:12:56.962 --> 00:13:01.399
community sample, we did not consider it a valid sample.

215
00:13:02.920 --> 00:13:07.532
So the reference stream there were 15 community samples ...

216
00:13:07.532 --> 00:13:10.279
collected between 2001 and 2012.

217
00:13:11.640 --> 00:13:17.522
The Bonfim control stream there were 29 samples ...

218
00:13:17.522 --> 00:13:21.639
collected between 2001 and 2017.

219
00:13:22.600 --> 00:13:26.186
In the Hinkson Creek rural portion,

00:13:26.186 --> 00:13:31.207
there were 32 samples collected between spring of ...

221
00:13:31.207 --> 00:13:33.598
2002 and spring of 2017.

222
00:13:35.840 --> 00:13:39.123
In the Hinkson Creek urban portion,

223
00:13:39.123 --> 00:13:43.719
there were 97 invert community samples collected ...

224
00:13:43.719 --> 00:13:45.798
between 2001 and 2017.

225
00:13:46.600 --> 00:13:51.731
I'd also like to note that during periods of fall of 2015 ...

226
00:13:51.731 --> 00:13:55.746
and fall of 2017, invert samples from rural ...

227
00:13:55.746 --> 00:14:00.096
portions of Hinkson Creek were not collected,

228
00:14:00.096 --> 00:14:04.669
again because of lack of flow or no flowing water,

229
00:14:04.669 --> 00:14:10.358
and also another condition during the spring of 2001 or 2012.

230
00:14:10.440 --> 00:14:13.280
Excuse me, in Urban Hinkson Creek.

231
00:14:13.440 --> 00:14:15.586
The lower three sites, one,

232
00:14:15.586 --> 00:14:16.799
two, and three,

233
00:14:16.799 --> 00:14:21.185
were not sampled due to an automotive parts store fire in ...

234
00:14:21.185 --> 00:14:24.731
the watershed, where automotive chemicals,

235

237
00:14:32.197 --> 00:14:35.277
downstream portion of Hinkson Creek.

238
00:14:39.120 --> 00:14:42.988
So of the 96 samples collected in the urban portion ...

239
00:14:42.988 --> 00:14:46.211
of Hinkson Creek, 47 of them meet the fully ...

If you look at Hinkson Creek rules segment 32 samples ...

244
00:15:01.381 --> 00:15:05.805
have been collected and 25 have met the fully supporting ...

245
00:15:05.805 --> 00:15:08.346

246
00:15:08.346 --> 00:15:09.758
or 78% of the time.

247
00:15:09.880 --> 00:15:12.901
So there's about a 30% change between rural ...

248
00:15:12.901 --> 00:15:15.839
Hinkson Creek and Urban Hinkson Creek.

249
00:15:16.000 --> 00:15:21.271
The Bonfam Control 20 of 29 samples have met the fully ...

00:15:37.803 --> 00:15:41.397
fully supporting aquatic life use.

254
00:15:41.560 --> 00:15:45.378
So not even the reference stream meets the 16 fully ...

255
00:15:45.378 --> 00:15:47.559
supporting 100% of the time.

256
00:15:47.720 --> 00:15:52.059
But we do notice that rural Hinkson Creek does meet ...

257
00:15:52.059 --> 00:15:56.599
the Miske score more often than urban hinks and creek.

258
00:15:57.560 --> 00:16:02.021
So of the 172 macroinvertebrate community ...

259
00:16:02.021 --> 00:16:06.110
samples, 44 invertebrate metrics were ...

260

00:16:12.880 --> 00:16:19.539
These were in the categories of richness and diversity and ...

00:16:50.680 --> 00:16:54.681
Metrics that include mayflies, stone flies,

After calculating all the invert metrics per 172 valid ...

274
00:17:23.219 --> 00:17:25.700

275
00:17:25.700 --> 00:17:27.279

355
00:22:18.280 --> 00:22:21.345
In the Hinkson Creek urban segment,

356
00:22:21.345 --> 00:22:26.091
there were 15 statistical significant trends in the fall ...

urban, there were 24 notable ...

362
00:22:41.938 --> 00:22:44.570
significant trends in the spring,

00:22:44.570 --> 00:22:48.291
14 indicating a positive or improved community,

364
00:22:48.291 --> 00:22:52.557
and five indicating a negative or degrading community.

365
00:22:53.240 --> 00:22:57.400
Within Hinkson Creek rule, there were 19 total trends of ...

367
00:23:01.382 --> 00:23:05.719
them indicating a positive or improved invert community.

368
00:23:06.360 --> 00:23:10.253
Within the spring and Hinkson Creek rule,

369
00:23:10.253 --> 00:23:14.479
there were 17 trends, six of them indicating a ...

370
00:23:14.479 --> 00:23:19.484
positive improved community and eleven indicating a ...

371
00:23:19.484 --> 00:23:22.598
negative or degraded community.

372
00:23:23.160 --> 00:23:27.657
It's important to note that in the reference stream there ...

373
00:23:27.657 --> 00:23:33.279
were no temporal trends of statistical significance in either season.

374
00:23:34.920 --> 00:23:37.701
In the nearby bonfim control stream,

375
00:23:37.701 --> 00:23:41.559
there were 28 trends of statistical significance,

376
00:23:41.559 --> 00:23:44.520

383
00:24:06.440 --> 00:24:07.480
I did skip over.

384
00:24:07.520 --> 00:24:10.661
There were some of the numbers don't match up to ...

385
00:24:10.661 --> 00:24:13.319
the total trends to positive negative.

386
00:24:13.440 --> 00:24:15.569
There are some invert metrics,

387
00:24:15.569 --> 00:24:19.172
we just don't know what an upward or downward pattern ...

388
00:24:19.172 --> 00:24:22.365
and over time mean and so those were considered ...

389
00:24:22.365 --> 00:24:23.839
neutral or variable.

390
00:24:24.000 --> 00:24:25.286
And Sam, would you like to add ...

391
00:24:25.286 --> 00:24:26.839
anything about neutral variable?

392
00:24:28.440 --> 00:24:31.440
Well, some variables are obviously ...

393
00:24:31.440 --> 00:24:34.040
signs of better water quality.

394
00:24:34.080 --> 00:24:38.548
Like anything relating to the EPT group,

395
00:24:38.548 --> 00:24:43.279
the more the better, and generally the more ...

396
00:24:43.279 --> 00:24:46.039
chironomides the worse.

397
00:24:46.480 --> 00:24:51.493
But there are some variables, macroinvert variables that ...

398
00:24:51.493 --> 00:24:56.711
whether it's higher or lower, doesn't necessarily mean that ...

399
00:24:56.711 --> 00:24:59.678
stream quality is better or worse.

400
00:24:59.760 --> 00:25:02.435
And those were ones that we're talking about when we ...

401
00:25:02.435 --> 00:25:03.679
say neutral variables.

402
00:25:04.680 --> 00:25:05.640

represent communities of different composition. You'll see.

Well, this table identifies ...

481
00:30:16.740 --> 00:30:23.232
macroinvertebrate taxa that were associated with how the ...

482
00:30:23.232 --> 00:30:28.399
sample groupings fell on the NMS scatter plot.

483
00:30:28.840 --> 00:30:33.211
And to really boil it down, there were some taxa that ...

484
00:30:33.211 --> 00:30:36.057
were strongly and consistently,

485
00:30:36.057 --> 00:30:40.021
and by that I mean both seasons associated with ...

486
00:30:40.021 --> 00:30:44.189
single study areas and these were the isopods sea ...

487
00:30:44.189 --> 00:30:47.035
Sidodia, which are the top things ...

488
00:30:47.035 --> 00:30:49.678
listed on both spring and fall.

489
00:30:50.400 --> 00:30:54.035
They were associated with Bonfim Creek,

490
00:30:54.035 --> 00:30:59.488
and the asiatic clam corbicula was strongly associated with ...

491
00:30:59.488 --> 00:31:03.230
the urban segment of Hinkson Creek in both ...

492
00:31:03.230 --> 00:31:05.796
seasons, and other taxa were ...

493
00:31:05.796 --> 00:31:11.035
consistently associated with multiple study areas and an ...

494
00:31:11.035 --> 00:31:15.953
example was the caddisfly trinodes which is the bottom ...

495
00:31:15.953 --> 00:31:17.556
row of this table.

496
00:31:18.360 --> 00:31:21.720
And these were found in samples from Bonfim Creek,

497
00:31:21.720 --> 00:31:25.480
from the reference streams and from the rural segment of ...

498
00:31:25.480 --> 00:31:26.600
Hinkson Creek.

499
00:31:26.640 --> 00:31:30.821
And what this is notable about this is they were not ...

500
00:31:30.821 --> 00:31:35.599
hardly ever found in the urban section of Hinkson Creek.

501
00:31:35.640 --> 00:31:42.030
So this is a taxon that we felt was good as a distinguishing ...

502
00:31:42.030 --> 00:31:44.959
taxon for the study areas.

503
00:31:47.760 --> 00:31:48.800
Thank you, Sam.

00:31:50.440 --> 00:31:55.032
When we were underway compiling data for this project ...

505
00:31:55.032 --> 00:31:59.420
and obviously right away we were able to understand ...

506
00:31:59.420 --> 00:32:03.399
through the ANoVA that there were chloride and ...

507
00:32:03.399 --> 00:32:07.583
conductance differences between the treatment ...

508
00:32:07.583 --> 00:32:11.052
groups and unique to Hinkson Creek urban ...

509
00:32:11.052 --> 00:32:13.807
portions, and that chloride and ...

510
00:32:13.807 --> 00:32:18.501
conductance follow a similar pattern among treatment ...

511
00:32:18.501 --> 00:32:21.562
groups, with them being the highest ...

512
00:32:21.562 --> 00:32:25.848
in Hinkson Creek urban, slightly less in the rule,

513
00:32:25.848 --> 00:32:28.705
slightly less in bonfam control,

514
00:32:28.705 --> 00:32:32.276
and the least in the reference condition.

515
00:32:35.960 --> 00:32:40.352
By plotting the chloride and conductance data from the ...

516
00:32:40.352 --> 00:32:43.312
control, we see that the conductance ...

517
00:32:43.312 --> 00:32:47.895
ranges from 275 to 500 micro siemens per centimeter in the ...

518

control, which is up to 30 milligrams ...

519
00:32:50.855 --> 00:32:53.719
per liter chloride concentration.

520
00:32:53.880 --> 00:32:57.287
In the reference, we see a lower range from ...

521
00:32:57.287 --> 00:33:01.667
175 to 475 microseconds per centimeter conductance,

522
00:33:01.667 --> 00:33:04.879
up to 25 milligrams per liter chloride.

523
00:33:05.200 --> 00:33:10.021
In Hinkson Creek rule, we observed a 275 to 575 ...

524
00:33:10.021 --> 00:33:15.857
microsemen per centimeter range of conductance with a ...

525
00:33:15.857 --> 00:33:20.678
maximum of 42 milligrams per liter chloride.

526
00:33:21.320 --> 00:33:25.607
And the urban segment of Hinkson Creek,

527
00:33:25.607 --> 00:33:29.894
we see a range of 275 microsiemens to 878 ...

528
00:33:29.894 --> 00:33:34.830
microsiemens and a maximum of 144 milligrams ...

529
00:33:34.830 --> 00:33:37.038
per liter chloride.

530
00:33:37.160 --> 00:33:43.720
So just keep in mind that 878 microsiemens per centimeter conductivity.

531
00:33:45.440 --> 00:33:48.520
Sorry, I went one too far.  Okay.

532
00:33:48.680 --> 00:33:51.160
Can you see the chloride conductance figure again?

533
00:33:54.240 --> 00:33:55.720
Yes.  Okay.

534
00:33:55.760 --> 00:33:58.800
I clicked one ahead, so sorry about that.

535
00:33:59.240 --> 00:34:01.598
So plotting those on a linear scale,

536
00:34:01.598 --> 00:34:04.664
we understand, or we can identify that there's ...

537
00:34:04.664 --> 00:34:08.438
a strong correlation between chloride and conductance.

538
00:34:09.360 --> 00:34:13.312
So using this information from the historic data,

539
00:34:13.312 --> 00:34:16.511
and again, these are collected in spring ...

540
00:34:16.511 --> 00:34:19.240
and fall, we have an understanding ...

541
00:34:19.240 --> 00:34:23.004
that this likely is not representing worst case ...

542
00:34:23.004 --> 00:34:27.238
condition in Hinkson Creek during the winter period.

543
00:34:30.480 --> 00:34:33.846
So doctor McCord and I deployed continuous ...

544
00:34:33.846 --> 00:34:37.960
conductance monitoring water quality data sands at ...

545
00:34:37.960 --> 00:34:42.448
five Hinkson Creek stations that correspond to historic ...

546
00:34:42.448 --> 00:34:44.879
invert monitoring locations.

547
00:34:46.040 --> 00:34:50.266
Data were collected at 30 minutes intervals and these ...

548
00:34:50.266 --> 00:34:54.492
sonds were left in Hinkson Creek to collect data for 24 ...

549
00:34:54.492 --> 00:34:56.839
hours a day, seven days a week.

550
00:34:57.440 --> 00:35:00.261
We deployed them on December 12,

551
00:35:00.261 --> 00:35:03.396
2019, and data and instrumentation ...

552
00:35:03.396 --> 00:35:05.799
were removed May 12 of 2020.

553
00:35:07.920 --> 00:35:10.960
So we deployed on December 12.

554
00:35:11.800 --> 00:35:16.436
Coincidentally, December 14 to December 17 ...

555
00:35:16.436 --> 00:35:22.200
was the first winter snow and ice event for the Columbia ...

556
00:35:22.200 --> 00:35:24.079
area in 2019 2020.

557
00:35:25.760 --> 00:35:29.988
On December 14, the area received 0.32 inches ...

558
00:35:29.988 --> 00:35:31.879
of rainfall and ice.

559
00:35:32.080 --> 00:35:38.909
On December 1636 inches of ice or 3.5 inches of snow,

560
00:35:38.909 --> 00:35:45.738
and then on December 17 0.14 inches of ice and rain or ...

561
00:35:45.738 --> 00:35:48.279
two inches of snow.

562
00:35:50.160 --> 00:35:53.440
Kingston Creek eight, which is at Rogers Road and ...

563
00:35:53.440 --> 00:35:55.200
upstream of the landfill.

564
00:35:56.360 --> 00:36:02.320
Conductance over this winter period remained relatively unchanged.

565
00:36:04.920 --> 00:36:08.797
And I did skip over on the time series plot are the flow ...

566
00:36:08.797 --> 00:36:13.379
data in black which represent the flow information collected ...

567
00:36:13.379 --> 00:36:15.758
by the USGS gauge at Providence.

568
00:36:16.080 --> 00:36:20.339
So the event the winter snow and ice event occurred on ...

569
00:36:20.339 --> 00:36:22.759
December 14 through the 17th.

570
00:36:22.920 --> 00:36:27.027
But on December 28 and 29th the area received more ...

571
00:36:27.027 --> 00:36:31.535
than one inch of rainfall and Hinkson Creek exceeded ...

572
00:36:31.535 --> 00:36:33.839
1000 cubic feet per second.

573
00:36:33.920 --> 00:36:36.480
So there was a large volume of water associated with ...

574
00:36:36.480 --> 00:36:39.159
rainfall and stormwater coming down Hinkson Creek.

575
00:36:39.280 --> 00:36:44.160
So during this period, Hinkson Creek ate at Rogers Road.

576
00:36:44.320 --> 00:36:46.693
It remained relatively unchanged from a ...

577
00:36:46.693 --> 00:36:47.879
conductance level.

578
00:36:47.920 --> 00:36:51.920
There was a slight increase, but you'll notice that once the ...

579
00:36:51.920 --> 00:36:55.200
rainfall and stormwater entered Hinkson Creek,

580
00:36:55.200 --> 00:36:58.240
there is a dramatic decrease in conductance.

581
00:36:59.560 --> 00:37:02.742
Our second station was at Hinkson Creek Seven,

582
00:37:02.742 --> 00:37:05.679
which corresponds to Hinkson Creek Road.

583
00:37:07.560 --> 00:37:11.248
We see slightly higher background conductance ...

584
00:37:11.248 --> 00:37:15.673
and again a slight increase associated with the timing of ...

585
00:37:15.673 --> 00:37:19.822
the winter event and then a dramatic decrease when the ...

586
00:37:19.822 --> 00:37:23.878
one inch rainfall event occurred later in the month.

587
00:37:25.120 --> 00:37:28.805
The next location, which is Hinkson Creek 5.5 at ...

588
00:37:28.805 --> 00:37:32.490
Green Valley drive, also at Broadway or close to ...

589
00:37:32.490 --> 00:37:35.991
Broadway Crossing, we notice the background ...

590
00:37:35.991 --> 00:37:39.676
conductance there is higher compared to the two ...

591
00:37:39.676 --> 00:37:43.546
upstream locations, but in response to the winter ...

592
00:37:43.546 --> 00:37:45.941
event from the 14th to the 17th,

593
00:37:45.941 --> 00:37:49.903
on the 16th we start to notice dramatic increases in ...

594
00:37:49.903 --> 00:37:55.155
conductance at Broadway Boulevard within main stem Hinkson Creek.

595
00:37:56.160 --> 00:38:00.519
If we look ahead on the time series to the one inch rainfall,

596
00:38:00.519 --> 00:38:04.611
we see conductance values drop similarly to that of the ...

597
00:38:04.611 --> 00:38:06.479
upstream two locations.

598
00:38:07.280 --> 00:38:11.119
The maximum point from our maximum value for ...

599
00:38:11.119 --> 00:38:15.684
conductance from Hinkson Creek 5.5 is over 3300 and ...

600
00:38:15.684 --> 00:38:20.975
microsiemens per centimeter, almost four times that of what ...

601
00:38:20.975 --> 00:38:24.399
we have data available in our analysis.

602
00:38:27.160 --> 00:38:30.778
Our fourth location was Pinkston Creek 3.5 at ...

603
00:38:30.778 --> 00:38:33.919
Recreation Drive and Providence Road.

604
00:38:35.160 --> 00:38:37.645
Again, we see similar background ...

605
00:38:37.645 --> 00:38:40.840
conductance prior to the event on the 13th.

606
00:38:41.600 --> 00:38:45.575
On the event on the 14th through the 17th from snow ...

607
00:38:45.575 --> 00:38:49.744
and ice is the delay in Hinkson Creek or the reaction ...

608
00:38:49.744 --> 00:38:54.398
in Hinkson Creek is slightly delayed compared to the next ...

609
00:38:54.398 --> 00:38:56.919
upstream station at Broadway.

610
00:38:57.120 --> 00:39:00.823
But we see a value of conductance more than 2000 ...

611
00:39:00.823 --> 00:39:05.286
microsiemens per centimeter and that carries through a ...

612
00:39:05.286 --> 00:39:10.319
longer duration than what the upstream Broadway location did.

613
00:39:10.360 --> 00:39:14.343
We see it carry on about a day longer and then also ...

614
00:39:14.343 --> 00:39:19.222
become diluted once the one inch precipitation event hits ...

615
00:39:19.222 --> 00:39:23.006
on December 28 29th, in which all conductance ...

616
00:39:23.006 --> 00:39:24.798
values were similar.

617
00:39:25.640 --> 00:39:30.364
And our last but not least location we are monitoring ...

618
00:39:30.364 --> 00:39:35.195
was Scott's Boulevard, which corresponds to station ...

619
00:39:35.195 --> 00:39:37.879
one, and again similar to 3.5.

620
00:39:38.000 --> 00:39:43.040
We have about a day delay between noticing impacts ...

621
00:39:43.040 --> 00:39:45.320
from the winter event.

622
00:39:45.680 --> 00:39:49.190
Background conductance before the winter event is ...

623
00:39:49.190 --> 00:39:53.679
similar among all the urban Hinkson Creek monitoring locations.

624
00:39:54.000 --> 00:39:57.169
And again we see once the rainfall event hits on ...

625
00:39:57.169 --> 00:40:00.420
December 28 29th, that conductance values fall ...

626
00:40:00.420 --> 00:40:04.158
back to a level similar to background concentrations.

627
00:40:04.280 --> 00:40:07.698
So this gave us an idea that we're under rust ...

628
00:40:07.698 --> 00:40:11.591
underestimating some of our winter chloride and ...

629
00:40:11.591 --> 00:40:14.439
conductance values in our data set.

630
00:40:16.120 --> 00:40:21.554
And you can actually see in the data set on December 18 ...

631
00:40:21.554 --> 00:40:26.988
from Hinkson Creek 3.5 and then there's a really high ...

632
00:40:26.988 --> 00:40:30.199
spike up to 3300 microsiemens.

633
00:40:30.280 --> 00:40:34.560
That spike is evident in Hinkson Creek downstream at the.

634
00:40:34.960 --> 00:40:37.680
Excuse me, I said 5.5.  I meant 5.5.

635
00:40:37.720 --> 00:40:39.040
I said 3.5.

636
00:40:39.360 --> 00:40:43.492
So it starts at 5.5 and then is evident at 3.5 and then is ...

637
00:40:43.492 --> 00:40:45.879
evident at Kingston Creek one.

638
00:40:47.840 --> 00:40:51.693
So over the 152 days conductance instrumentation ...

639
00:40:51.693 --> 00:40:54.628
were deployed, we collected more than ...

640
00:40:54.628 --> 00:40:56.279
30,000 data records.

641
00:40:56.480 --> 00:41:00.158
These are the maximum values from the monitoring ...

642
00:41:00.158 --> 00:41:03.119
locations, with 5.5 being the highest.

643
00:41:03.680 --> 00:41:06.080
And he's increasing one thing the next.

644
00:41:06.480 --> 00:41:09.713
Average concentrations, or average conductance ...

645
00:41:09.713 --> 00:41:12.561
values generally increase from upstream to ...

646
00:41:12.561 --> 00:41:15.332
downstream, but Hinkson Creek's 5.5 still ...

647
00:41:15.332 --> 00:41:18.257
remain the highest conductance value from an ...

648
00:41:18.257 --> 00:41:19.719
average perspective.

649
00:41:20.280 --> 00:41:24.366
Looking at the 90th percentile the data collected,

650
00:41:24.366 --> 00:41:28.547
there is a complete linear increase from upstream to ...

651
00:41:28.547 --> 00:41:30.922
downstream, suggesting that ...

652
00:41:30.922 --> 00:41:36.718
concentrations over time are persistently higher at Hinkson Creek one.

653
00:41:39.600 --> 00:41:43.336
So in all this, we can't forget that Hinkson ...

654
00:41:43.336 --> 00:41:45.759
Creek is an urban watershed.

655
00:41:45.920 --> 00:41:49.295
The Missouri Department of Natural Resources manages ...

656
00:41:49.295 --> 00:41:52.743
a Missouri environmental emergency response tracking ...

657
00:41:52.743 --> 00:41:53.843
system, or Mertz,

658
00:41:53.843 --> 00:41:56.924
and then the Missouri Department of Conservation ...

659
00:41:56.924 --> 00:41:59.198
manages a fish kill report database.

660
00:41:59.720 --> 00:42:05.242
The heat map shown on your right documents Mertz or ...

661
00:42:05.242 --> 00:42:11.027
NDC fish kill reports in the Hinkson Creek watershed ...

662
00:42:11.027 --> 00:42:12.999
from 2001 to 2017.

663
00:42:13.720 --> 00:42:18.160
These incidents include things such as vehicular ...

664
00:42:18.160 --> 00:42:22.072
accident fire, we talked about the O'Reilly ...

665
00:42:22.072 --> 00:42:27.358
auto auto parts fire, earlier malfunctioning or failures.

666
00:42:27.520 --> 00:42:31.486
So there have been several documented potable water ...

667
00:42:31.486 --> 00:42:35.362
line breaks in the city that have leaked into nearby ...

668
00:42:35.362 --> 00:42:39.238
tributaries, documenting aquatic life toxicity.

669
00:42:39.800 --> 00:42:42.632
And there's also been some improper disposal of ...

670
00:42:42.632 --> 00:42:45.039
chlorinated water from swimming pools.

671
00:42:49.240 --> 00:42:53.526
Kind of summarizing all this information together ...

672
00:42:53.526 --> 00:42:57.912
developed landscape in the Hinkson Creek watershed ...

673
00:42:57.912 --> 00:43:00.304
has increased from four to 5%

674
00:43:00.304 --> 00:43:01.799
from 2001 to 2016.

675
00:43:02.560 --> 00:43:05.376
The invert metrics within Hinkson Creek are not ...

676
00:43:05.376 --> 00:43:07.559
consistently decreasing over time.

677
00:43:08.280 --> 00:43:11.370
There are evident water chemistry differences ...

678
00:43:11.370 --> 00:43:14.692
between Hinkson Creek, the control and reference ...

679
00:43:14.692 --> 00:43:17.164
streams, and those most notably being ...

680
00:43:17.164 --> 00:43:19.559
conductance, sulfate and chloride.

681
00:43:19.920 --> 00:43:23.574
Invert metrics within urban Hingsey Creek in the spring ...

682
00:43:23.574 --> 00:43:26.839
season correlate well with increased chlorides.

683
00:43:27.480 --> 00:43:30.530
Nutrient levels are similar between urban and rural ...

684
00:43:30.530 --> 00:43:33.719
hanks and creek and the control and reference streams.

685
00:43:34.280 --> 00:43:37.362
And through our experiment collecting data,

686
00:43:37.362 --> 00:43:40.931
conductance is a great surrogate for dissolved ions ...

687
00:43:40.931 --> 00:43:42.959
such as sulfate and chloride.

688
00:43:43.000 --> 00:43:48.222
Monitoring recommendations from our project from what ...

689
00:43:48.222 --> 00:43:53.333
we've learned is that a lot of the impact on urban hincks ...

690
00:43:53.333 --> 00:43:56.999
and creek comes from non point sources.

691
00:43:57.200 --> 00:43:59.300
Therefore, we would promote the ...

692
00:43:59.300 --> 00:44:02.566
development of a watershed based management plan ...

693
00:44:02.566 --> 00:44:05.988
which will also allow for implementation projects,

694
00:44:05.988 --> 00:44:10.032
identification of projects, and prioritization of projects ...

695
00:44:10.032 --> 00:44:11.198
in the watershed.

696
00:44:11.880 --> 00:44:15.551
Focusing on non structural bmp's and winter road ...

697
00:44:15.551 --> 00:44:18.416
treatment, doing that by outreach and ...

698
00:44:18.416 --> 00:44:21.192
education, and striving to find that ...

699
00:44:21.192 --> 00:44:25.758
balance between public safety and aquatic life protection.

700
00:44:26.120 --> 00:44:30.342
Over the last year or two, the science team has been ...

701
00:44:30.342 --> 00:44:33.257
involved with folks from the city,

702
00:44:33.257 --> 00:44:36.273
the county, the university in MoDOT ...

703
00:44:36.273 --> 00:44:40.998
understanding how winter road treatment is applied and ...

704
00:44:40.998 --> 00:44:45.119
all these entities follow federal Department of ...

705
00:44:45.119 --> 00:44:49.442
Transportation guidance when it comes to treating ...

706
00:44:49.442 --> 00:44:52.357
roads and calibrating spreaders.

707
00:44:53.480 --> 00:44:57.088
Another non structural BMP focus would be looking ...

708
00:44:57.088 --> 00:45:01.039
toward treatment alternatives other than chlorides.

709
00:45:02.000 --> 00:45:04.475
And then, as Laura Weissman gave a ...

710
00:45:04.475 --> 00:45:08.895
great presentation last week, that was more of a structural ...

711
00:45:08.895 --> 00:45:12.961
bmp focus that revolved around attenuating rainwater ...

712
00:45:12.961 --> 00:45:14.198
and stormwater.

713
00:45:14.560 --> 00:45:17.890
So as much as possible, ground infiltrates instead of ...

714
00:45:17.890 --> 00:45:19.000
just running off.

715
00:45:20.640 --> 00:45:23.530
Another prime recommendation out of our ...

716
00:45:23.530 --> 00:45:26.760
project came to bmp performance monitoring.

717
00:45:27.120 --> 00:45:29.560
All the entities, like I said,

718
00:45:29.560 --> 00:45:33.952
follow FDOT guidance when it comes to applying winter ...

719
00:45:33.952 --> 00:45:35.318
road treatment.

720
00:45:35.480 --> 00:45:38.315
But at what point do we understand what bmP's are ...

721
00:45:38.315 --> 00:45:40.229
working, how it's affecting the ...

722
00:45:40.229 --> 00:45:42.639
community and affecting Hinkson Creek.

723
00:45:42.760 --> 00:45:46.375
So by retrofitting the Providence USGS gauge with ...

724
00:45:46.375 --> 00:45:50.163
a conductance instrument, which can be easily done,

725
00:45:50.163 --> 00:45:53.864
you'd have a long term understanding of winter road ...

726
00:45:53.864 --> 00:45:55.758
impacts from year to year.

727
00:45:55.800 --> 00:45:59.320
Because we live in Missouri and no two years are alike.

728
00:45:59.400 --> 00:46:00.935
If you don't like the weather today,

729
00:46:00.935 --> 00:46:02.879
just wait till tomorrow. It'll be different.

730
00:46:04.360 --> 00:46:07.771
And then also with bmp performance monitoring,

731
00:46:07.771 --> 00:46:11.352
we suggest a rural Hinkson Creek flow and then also ...

732
00:46:11.352 --> 00:46:15.615
conductance gauge station to understand flow differences ...

733
00:46:15.615 --> 00:46:19.196
between rural portions of Hinkson Creek and urban ...

734
00:46:19.196 --> 00:46:21.157
portions of Hinkson Creek.

735
00:46:22.400 --> 00:46:26.354
A high winter or a high resolution winter season ...

736
00:46:26.354 --> 00:46:30.209
conductance assessment could be performed to ...

737
00:46:30.209 --> 00:46:35.053
identify tributaries and storm sewer or storm drains that ...

738
00:46:35.053 --> 00:46:38.117
contribute high levels of chloride.

739
00:46:38.240 --> 00:46:42.959
We know that the Hinkson Creek 5.5 Broadway site is a ...

740
00:46:42.959 --> 00:46:47.678
good area or is a good area for increased chlorides,

741
00:46:47.678 --> 00:46:52.836
but you could refine that to understand tributaries and ...

742
00:46:52.836 --> 00:46:56.677
identify sources to a higher resolution.

743
00:46:58.120 --> 00:47:01.784
An invertebrate drift study during the winter season ...

744
00:47:01.784 --> 00:47:04.959
would further confirm the chloride stressor.

745
00:47:05.760 --> 00:47:10.144
Understanding the movement and lord lack thereof during ...

746
00:47:10.144 --> 00:47:14.163
the season would confirm whether chloride is really ...

747
00:47:14.163 --> 00:47:17.542
imposing a stress to the community and going ...

748
00:47:17.542 --> 00:47:22.200
through all the previous data collection through whether it ...

749
00:47:22.200 --> 00:47:24.118
be habitat and sediment.

750
00:47:24.160 --> 00:47:26.120
There's been some great data collected.

751
00:47:26.520 --> 00:47:28.181
However, as I mentioned,

752
00:47:28.181 --> 00:47:31.504
a lot of that data was collected one time or it is not ...

753
00:47:31.504 --> 00:47:34.748
collected in a standardized manner that makes it ...

754
00:47:34.748 --> 00:47:37.438
comparable from one data set to another.

755
00:47:37.640 --> 00:47:41.214
So we would suggest to the cam that habitat and ...

756
00:47:41.214 --> 00:47:45.258
sediment assessments be standardized for Hinkson ...

757
00:47:45.258 --> 00:47:49.302
Creek into the future so consistency we can use them ...

758
00:47:49.302 --> 00:47:51.277
to their maximum extent.

759
00:47:55.000 --> 00:47:58.815
And with that the full report is available on ...

760
00:47:58.815 --> 00:48:03.559
helpthehinksen.org and I thank you guys for your time.

761
00:48:03.640 --> 00:48:08.232
I think Tim is going to finish up and then we'll entertain ...

762
00:48:08.232 --> 00:48:10.479
any questions you may have.

763
00:48:13.720 --> 00:48:16.040
Hopefully everyone's still there, not asleep.

764
00:48:19.680 --> 00:48:24.080
Thanks Cody.  Let me see if I can open this.  Great job.

765
00:48:24.960 --> 00:48:33.360
Nice to hear your voice doctor Samdhden.

766
00:48:33.560 --> 00:48:37.360
Well bear with me for a moment.

767
00:48:43.680 --> 00:48:44.920
Oh it worked.

768
00:48:45.080 --> 00:48:53.280
Can you all see that coming through?

769
00:48:56.480 --> 00:48:57.520
There we go.

770
00:48:59.160 --> 00:49:00.400
Yeah, I can see it Tim.

771
00:49:00.960 --> 00:49:02.280
Okay, wonderful.

772
00:49:02.760 --> 00:49:05.480
Just a few more slides to finish up.

773
00:49:06.880 --> 00:49:10.012
This is what's wrong with Hinkson Creek,

774
00:49:10.012 --> 00:49:13.771
which is the conceptual ecological model from the ...

775
00:49:13.771 --> 00:49:15.919
science strategy document.

776
00:49:16.280 --> 00:49:20.761
It shows the interactions of multiple stressors in ...

777
00:49:20.761 --> 00:49:25.554
Hinkson Creek that are possible and the complexities ...

778
00:49:25.554 --> 00:49:28.784
of those and basically the unknowns,

779
00:49:28.784 --> 00:49:31.910
the unknown interactions of those,

780
00:49:31.910 --> 00:49:35.557
of those structures and those stressors.

781
00:49:35.600 --> 00:49:44.040
Rather the study hit on multiple pieces of this model.

782
00:49:44.160 --> 00:49:48.525
I was going to highlight them, but it certainly covered the ...

783
00:49:48.525 --> 00:49:51.554
covered temperature, sediment regime,

784
00:49:51.554 --> 00:49:53.959
channel flow regime and others.

785
00:49:55.200 --> 00:49:59.720
So those interact and it's rather complex and we'll have ...

786
00:49:59.720 --> 00:50:04.240
more to say about that in the science strategy document.

787
00:50:08.000 --> 00:50:10.760
So what is wrong with Hinkson Creek?

788
00:50:10.920 --> 00:50:13.476
It's affected by multiple issues,

789
00:50:13.476 --> 00:50:17.707
certainly geology and climate, historical changes with ...

790
00:50:17.707 --> 00:50:20.616
respect to point and non point sources,

791
00:50:20.616 --> 00:50:23.436
chemical pathways, mostly chemical,

792
00:50:23.436 --> 00:50:24.758
mostly physical.

793
00:50:24.840 --> 00:50:27.160
And Cody said quite a bit about that.

794
00:50:27.320 --> 00:50:31.489
And then the interaction of those pathways and how they ...

795
00:50:31.489 --> 00:50:35.658
affect the community and then certainly interactions ...

796
00:50:35.658 --> 00:50:39.827
with stream habitats and exposures to stream habitats ...

797
00:50:39.827 --> 00:50:43.633
and not the least to mention perhaps lack of stream ...

798
00:50:43.633 --> 00:50:47.349
habitat and how they all affect the invertebrate ...

799
00:50:47.349 --> 00:50:51.518
community which is rather complex and hard to sort out.

800
00:50:51.560 --> 00:50:55.474
So this study was helpful with some of those things,

801
00:50:55.474 --> 00:50:56.839
those stressors.

802
00:50:58.400 --> 00:51:01.332
We feel the study provided new information towards ...

803
00:51:01.332 --> 00:51:03.719
finding potential causes of impairment.

804
00:51:04.240 --> 00:51:08.260
And these additional metrics provided very useful addition ...

805
00:51:08.260 --> 00:51:12.122
towards our understanding of the invertebrate community ...

806
00:51:12.122 --> 00:51:15.038
and the responses to stressors and Hinkson.

807
00:51:15.080 --> 00:51:17.000
By sorting those out even further.

808
00:51:17.200 --> 00:51:20.480
There's an immense amount of work here that Cody did not show.

809
00:51:20.840 --> 00:51:22.360
We consider this a worthwhile.

810
00:51:22.440 --> 00:51:25.960
The science team considers this a worthwhile use of funds.

811
00:51:27.520 --> 00:51:31.046
We did want to say the process provides additional ...

812
00:51:31.046 --> 00:51:34.824
lines of evidence that while chlorides is an apparent ...

813
00:51:34.824 --> 00:51:37.510
cause of impairment in Hinkson Creek,

814
00:51:37.510 --> 00:51:40.196
there are also likely other physical,

815
00:51:40.196 --> 00:51:43.470
chemical or hydrological issues that are also ...

816
00:51:43.470 --> 00:51:47.836
contributing to hydrologic two or other aquatic impairment.

817
00:51:48.040 --> 00:51:50.757
The difficulty here is, for example,

818
00:51:50.757 --> 00:51:55.052
sediment is just very hard to sort out and track the effects ...

819
00:51:55.052 --> 00:51:57.945
of sediment on the community because it ...

820
00:51:57.945 --> 00:52:00.838
changes over time and changes quickly.

821
00:52:01.360 --> 00:52:04.680
So with that, our thanks.

822
00:52:04.800 --> 00:52:05.800
And I think we.

823
00:52:05.840 --> 00:52:08.320
We left it open to questions.

824
00:52:15.240 --> 00:52:16.320
This is Rob Jacobson.

825
00:52:16.360 --> 00:52:18.600
Can you guys hear me?  Yes, we can.

826
00:52:18.680 --> 00:52:20.878
Also, if participants want to hit the ...

827
00:52:20.878 --> 00:52:22.934
hide stage, the hide stage button,

828
00:52:22.934 --> 00:52:25.558
that will bring up the kind of viewer as well.

829
00:52:25.720 --> 00:52:27.160
We can hear you, Rob.

830
00:52:30.680 --> 00:52:32.080
Okay, you can hear me.  Good.

831
00:52:32.200 --> 00:52:38.993
So I just wanted to just put a little bit more of an emphasis ...

832
00:52:38.993 --> 00:52:41.399
on Tim's last point.

833
00:52:41.520 --> 00:52:45.244
Page 5.2 in the data mining report says therefore multiple ...

834
00:52:45.244 --> 00:52:48.816
stressors are likely causes the aquatic life threshold ...

835
00:52:48.816 --> 00:52:51.400
impairment of bourbon, Hanks and Creek.

836
00:52:51.600 --> 00:52:53.931
Of the potential stressors examined,

837
00:52:53.931 --> 00:52:57.063
analysis of hydrology in stream habitats sediment ...

838
00:52:57.063 --> 00:53:00.559
were limited due to the absence or lack of available data.

839
00:53:00.720 --> 00:53:04.108
And so you could see through Cody's presentation ...

840
00:53:04.108 --> 00:53:08.239
more emphasis on chloride because we've got chloride data.

841
00:53:08.280 --> 00:53:10.546
We've got another chloride talk coming out that Dan ...

842
00:53:10.546 --> 00:53:11.599
Obreck is going to give.

843
00:53:11.720 --> 00:53:14.535
So science team thinks that there's something going on ...

844
00:53:14.535 --> 00:53:15.759
with chloride for sure.

845
00:53:16.280 --> 00:53:20.810
But what was emphasized, and Cody did this and Tim ...

846
00:53:20.810 --> 00:53:23.903
did this, is that we don't have the ...

847
00:53:23.903 --> 00:53:29.759
same amount of data to look at habitat and sediment in the river.

848
00:53:29.800 --> 00:53:33.889
And so we don't want to prematurely go all in on one ...

849
00:53:33.889 --> 00:53:37.879
thing until we get a better understanding over.

850
00:53:48.160 --> 00:53:52.163
There was a question that came in by text about ...

851
00:53:52.163 --> 00:53:57.114
whether chlorides are strong enough stressor to induce ...

852
00:53:57.114 --> 00:53:58.799
behavioral drift.

853
00:53:59.120 --> 00:54:03.360
And that was, we don't know.

854
00:54:03.440 --> 00:54:08.678
Maybe that's something that would be addressed by that ...

855
00:54:08.678 --> 00:54:12.550
proposed, that recommended drift study ...

856
00:54:12.550 --> 00:54:16.422
that would correspond with continuous,

857
00:54:16.422 --> 00:54:19.838
probably conductance monitoring.

858
00:54:19.960 --> 00:54:23.337
So that was where that came from was,

859
00:54:23.337 --> 00:54:27.839
well, what effect does that have on the inverts?

860
00:54:27.840 --> 00:54:31.011
So we think that the answer to that may be yes,

861
00:54:31.011 --> 00:54:33.839
but we don't have any conclusive proof.

862
00:54:34.440 --> 00:54:36.960
Yeah. That would address whether ...

863
00:54:36.960 --> 00:54:40.920
or not we look at things from a toxicity perspective.

864
00:54:41.040 --> 00:54:44.874
We have acute and chronic criteria,

865
00:54:44.874 --> 00:54:48.836
but before those thresholds are met,

866
00:54:48.836 --> 00:54:52.159
do inverts flee their habitat?

867
00:54:52.240 --> 00:54:55.567
And so that would get at assessing whether they do or ...

868
00:54:55.567 --> 00:54:57.656
not, which could lead to a better ...

869
00:54:57.656 --> 00:55:01.370
understanding of why we get variable results from season ...

870
00:55:01.370 --> 00:55:02.917
to season, year to year.

871
00:55:07.320 --> 00:55:09.080
Cody, this is Rob again.

872
00:55:09.400 --> 00:55:13.285
One thing I just thought maybe needed to be clarified ...

873
00:55:13.285 --> 00:55:16.905
was in the fish kills, where you saw the effects of ...

874
00:55:16.905 --> 00:55:18.318
pollutable water.

875
00:55:18.480 --> 00:55:20.100
That's a problem, right,

876
00:55:20.100 --> 00:55:22.337
because the water's chlorinated,

877
00:55:22.337 --> 00:55:23.879
is that right? Yes, sir.

878
00:55:25.760 --> 00:55:26.680
Thank you.

879
00:55:27.400 --> 00:55:28.400
And I will add to that.

880
00:55:28.440 --> 00:55:31.755
There were no documented fish kills from potable water ...

881
00:55:31.755 --> 00:55:34.926
within Hinkson Creek, but there were several within ...

882
00:55:34.926 --> 00:55:36.799
tributaries of Hinkson Creek.

883
00:55:48.320 --> 00:55:50.200
So this is Rob.  I'm going to ask another question.

884
00:55:50.280 --> 00:55:52.160
While everybody's thinking about questions.

885
00:55:52.520 --> 00:55:54.386
There's so much data here that every time I hear it,

886
00:55:54.386 --> 00:55:55.719
I've heard this three or four times.

887
00:55:55.760 --> 00:55:57.760
Now I see something else.

888
00:55:58.120 --> 00:56:00.754
The relationship with corbicula was interesting,

889
00:56:00.754 --> 00:56:02.959
that it's associated with the urban areas.

890
00:56:04.440 --> 00:56:07.029
Do you know, can you say for sure that ...

891
00:56:07.029 --> 00:56:10.912
corbicula had the capability of being throughout the ...

892
00:56:10.912 --> 00:56:14.191
drainage basin, or is that possibly a limit on ...

893
00:56:14.191 --> 00:56:18.678
its ability to migrate upstream or colonize those areas over?

894
00:56:19.520 --> 00:56:20.880
I think it's a.

895
00:56:21.080 --> 00:56:25.040
That's a good question, and I think that's certainly a big influence.

896
00:56:26.680 --> 00:56:28.120
I would have to look at the data.

897
00:56:28.160 --> 00:56:32.480
It's been a while since I've looked at the data tables.

898
00:56:33.520 --> 00:56:36.560
Certainly, you know, that's.

899
00:56:36.680 --> 00:56:43.200
That's why just the regional possibilities of.

900
00:56:44.800 --> 00:56:49.811
That's probably why it's lower at the reference streams and ...

901
00:56:49.811 --> 00:56:53.519
at Bonfem, but the possibilities are there.

902
00:56:54.160 --> 00:56:59.560
So it's another thing where we don't know how to.  How much.

903
00:57:01.880 --> 00:57:06.906
How much influence to attribute to just a natural,

904
00:57:06.906 --> 00:57:10.975
you know, a natural regional difference ...

905
00:57:10.975 --> 00:57:13.488
as opposed to a, you know,

906
00:57:13.488 --> 00:57:16.958
water quality impact difference.

907
00:57:17.920 --> 00:57:20.802
And as we all know, the lower segments of ...

908
00:57:20.802 --> 00:57:22.898
Hinkson Creek, lower sites,

909
00:57:22.898 --> 00:57:24.470
you know, one and two,

910
00:57:24.470 --> 00:57:26.391
are impacted by, you know,

911
00:57:26.391 --> 00:57:30.671
backwater conditions from the Missouri river when it's at ...

912
00:57:30.671 --> 00:57:32.156
really high stages.

913
00:57:32.360 --> 00:57:33.704
So, you know,

914
00:57:33.704 --> 00:57:38.959
whereas Bonfam Creek.edu reference streams do not ...

915
00:57:38.959 --> 00:57:41.159
have that condition.

916
00:57:53.120 --> 00:57:54.560
This is Erin Keys.

917
00:57:54.680 --> 00:57:55.206
Hey, Cody,

918
00:57:55.206 --> 00:57:57.079
thanks so much for that presentation.

919
00:57:57.560 --> 00:58:01.892
I had a quick question on you talked about on one of the ...

920
00:58:01.892 --> 00:58:06.618
slides that I think it was the caddisfly was very common in ...

921
00:58:06.618 --> 00:58:11.245
the reference streams and in the rural parts of Hinkson,

922
00:58:11.245 --> 00:58:12.918
but not in the urban.

923
00:58:13.920 --> 00:58:17.896
Can you guys tell me a little bit about the life cycle of that ...

924
00:58:17.896 --> 00:58:22.359
caddisfly and what kind of habitat it likes and that sort of thing.

925
00:58:22.520 --> 00:58:26.936
So we could think about why maybe it's not in the urban ...

926
00:58:26.936 --> 00:58:31.452
sections from a habitat perspective and not just from ...

927
00:58:31.452 --> 00:58:33.559
a chemical perspective.

928
00:58:35.400 --> 00:58:36.307
Well, that's.

929
00:58:36.307 --> 00:58:37.139
This is, Sam,

930
00:58:37.139 --> 00:58:38.879
that's a good question too.

931
00:58:39.680 --> 00:58:43.946
And one of the potential confusing things here is ...

932
00:58:43.946 --> 00:58:48.732
when we talk about indicator taxa on that slide that was ...

933
00:58:48.732 --> 00:58:52.894
really relating to an explanation of some of the ...

934
00:58:52.894 --> 00:58:56.119
results in the ordination analysis.

935
00:58:56.280 --> 00:58:59.648
But to get to what I think you're asking,

936
00:58:59.648 --> 00:59:03.629
and correct me if I'm wrong, is what kind of tax,

937
00:59:03.629 --> 00:59:07.406
if we went out there and looked in the stream,

938
00:59:07.406 --> 00:59:09.958
what would we expect to find a.

939
00:59:10.040 --> 00:59:13.240
In the less impacted areas, the rural areas,

940
00:59:13.240 --> 00:59:16.959
the reference streams, bon fem and not in the urban.

941
00:59:18.040 --> 00:59:19.080
In the urban stream.

942
00:59:19.120 --> 00:59:24.000
And we also did identify some of those.

943
00:59:24.440 --> 00:59:31.426
And it's not necessarily a matter of habitat differences ...

944
00:59:31.426 --> 00:59:38.412
because the habitats are available in the rural sections ...

945
00:59:38.412 --> 00:59:41.759
and the urban sections too.

946
00:59:41.960 --> 00:59:47.821
But what the difference is and what we think the ...

947
00:59:47.821 --> 00:59:51.879
differences are causing these.

948
00:59:51.960 --> 00:59:55.640
What we propose is indicator tax or indicator metrics.

949
00:59:56.840 --> 01:00:00.800
We thought those differences were related to stream quality.

950
01:00:03.800 --> 01:00:08.640
That particular tax on was trinodes that I think you were referring to.

951
01:00:09.560 --> 01:00:13.056
That was an important tax on in explaining some of the ...

952
01:00:13.056 --> 01:00:15.519
results in the ordination analysis.

953
01:00:15.680 --> 01:00:20.188
But it was not one of our proposed indicator tax that ...

954
01:00:20.188 --> 01:00:22.599
are outlined in the report.

955
01:00:23.200 --> 01:00:26.368
There are two caddisflies there,

956
01:00:26.368 --> 01:00:27.839
and a stonefly.

957
01:00:28.040 --> 01:00:33.529
And they're all taxa that are commonly found in the rural ...

958
01:00:33.529 --> 01:00:39.719
portions of Hinkson Creek and not so much in the urban portions.

959
01:00:40.040 --> 01:00:45.040
They're all considered very intolerant to pollution.

960
01:00:45.480 --> 01:00:50.431
And they're all members of other kind of important trait ...

961
01:00:50.431 --> 01:00:56.119
categories that we can go into in addition to this conversation.

962
01:00:56.240 --> 01:00:58.200
So there's a lot of background there.

963
01:00:58.280 --> 01:01:01.807
But to the answer, I think boil down the answer ...

964
01:01:01.807 --> 01:01:03.199
to your question.

965
01:01:03.320 --> 01:01:07.940
It wasn't necessarily habitat differences between the ...

966
01:01:07.940 --> 01:01:11.479
urban and rural segments of Hinkson Creek.

967
01:01:11.520 --> 01:01:13.240
In terms of habitat availability.

968
01:01:13.440 --> 01:01:16.360
We think it's just the stream quality.

969
01:01:16.520 --> 01:01:20.680
That's why these tacks are found someplace commonly.

970
01:01:20.840 --> 01:01:24.670
For example, the rural segment and rarely ...

971
01:01:24.670 --> 01:01:26.639
in the urban segment.

972
01:01:27.040 --> 01:01:29.700
So when you say stream quality,

973
01:01:29.700 --> 01:01:31.439
you mean the actual.

974
01:01:32.040 --> 01:01:33.680
Do you call that water chemistry?

975
01:01:33.720 --> 01:01:36.398
The actual content of the water,

976
01:01:36.398 --> 01:01:38.679
what's in the water itself?

977
01:01:39.320 --> 01:01:41.280
It really encompasses everything.

978
01:01:41.600 --> 01:01:48.520
The habitat, the habitat quality and the stream.

979
01:01:49.600 --> 01:01:54.000
Water chemistry quality, and also the physical ...

980
01:01:54.000 --> 01:01:56.970
conditions that may be natural,

981
01:01:56.970 --> 01:01:58.400
like high flow.

982
01:01:58.480 --> 01:02:02.760
But they'll differ between those two study areas.

983
01:02:03.120 --> 01:02:06.040
So it's really a combination of all of those.

984
01:02:06.960 --> 01:02:11.155
Okay, and then a second question,

985
01:02:11.155 --> 01:02:17.148
or I'm not sure what it is, but you guys had a slide ...

986
01:02:17.148 --> 01:02:25.239
about how the positive trends for some of the different metrics.

987
01:02:25.400 --> 01:02:31.040
And so just to recap, does that mean positive in a ...

988
01:02:31.040 --> 01:02:36.539
good way so that we have been improving parts of ...

989
01:02:36.539 --> 01:02:39.359
Hinkson Creek? Is that.

990
01:02:39.880 --> 01:02:43.231
Can I make that statement based on some of those ...

991
01:02:43.231 --> 01:02:44.519
positive trends?

992
01:02:46.200 --> 01:02:48.626
Erin, the trends that we noted in ...

993
01:02:48.626 --> 01:02:51.139
urban Hinkson Creek, for example,

994
01:02:51.139 --> 01:02:55.039
they were both positive and negative in both seasons.

995
01:02:55.440 --> 01:02:57.756
But for example, in the spring,

996
01:02:57.756 --> 01:03:01.855
there were 14 metrics that indicated an improvement or ...

997
01:03:01.855 --> 01:03:04.439
a benefit to the invert community.

998
01:03:04.880 --> 01:03:09.772
And then there were five metrics indicating decline or a ...

999
01:03:09.772 --> 01:03:14.039
degradation or degrade to the inbert community.

1000
01:03:14.200 --> 01:03:17.772
So there was a mixed bag, but there were more positive ...

1001
01:03:17.772 --> 01:03:19.639
than there were negatives.

1002
01:03:19.720 --> 01:03:21.280
Take that with a grain of salt.

1003
01:03:22.440 --> 01:03:25.083
Sure. I guess I just want to say that ...

1004
01:03:25.083 --> 01:03:29.276
at least some of our efforts seem to be having a positive ...

1005
01:03:29.276 --> 01:03:31.190
effect versus, you know,

1006
01:03:31.190 --> 01:03:33.651
you know, some of the data from 20 ...

1007
01:03:33.651 --> 01:03:34.836
years ago, say,

1008
01:03:34.836 --> 01:03:36.477
absolutely, I would.

1009
01:03:36.640 --> 01:03:39.422
If they weren't having a positive effect,

1010
01:03:39.422 --> 01:03:42.998
then we would see all these invert metrics continue to ...

1011
01:03:42.998 --> 01:03:44.985
decline or persist, you know,

1012
01:03:44.985 --> 01:03:49.038
not see any positive feedback from the community, but we are.

1013
01:03:49.360 --> 01:03:50.920
Okay, thank you.

1014
01:03:51.800 --> 01:03:52.511
Hey, Cody,

1015
01:03:52.511 --> 01:03:56.149
we also just got a question in from Amy saying which taxa ...

1016
01:03:56.149 --> 01:03:58.838
are considered to be the reference taxa?

1017
01:03:59.920 --> 01:04:07.840
Okay, well.

1018
01:04:10.200 --> 01:04:11.320
Oh, okay.

1019
01:04:11.480 --> 01:04:15.908
You mean associated with the reference streams?

1020
01:04:15.908 --> 01:04:16.880
Yes. Okay.

1021
01:04:17.440 --> 01:04:19.800
Those are choral.

1022
01:04:19.840 --> 01:04:21.920
Terpes is a mayfly.

1023
01:04:22.000 --> 01:04:24.040
Nectopsyche is a caddisfly.

1024
01:04:25.000 --> 01:04:26.240
Those were.

1025
01:04:28.720 --> 01:04:31.160
And acentrella is another mayfly.

1026
01:04:31.360 --> 01:04:36.829
I don't know the tolerance values of those,

1027
01:04:36.829 --> 01:04:42.298
but they're all in the moderate tolerance,

1028
01:04:42.298 --> 01:04:47.159
moderate pollution tolerance range.

1029
01:04:47.280 --> 01:04:51.960
And then again, those were things that were.

1030
01:04:52.120 --> 01:04:54.680
They're on that table because they were found.

1031
01:04:55.480 --> 01:04:58.615
When they were found, it was basically,

1032
01:04:58.615 --> 01:05:02.320
it was nearly always in the reference streams,

1033
01:05:02.320 --> 01:05:06.880
not necessarily because they're absent or that they're.

1034
01:05:07.800 --> 01:05:12.883
That poor quality eliminated them from the others,

1035
01:05:12.883 --> 01:05:18.439
but just that was how the statistical patterns emerged.

1036
01:05:20.040 --> 01:05:20.960
Thank you.

1037
01:05:40.680 --> 01:05:43.487
So is this a common thing to do,

1038
01:05:43.487 --> 01:05:49.439
a macroinvertebrate data mining or is this a rarity for you all?

1039
01:05:50.000 --> 01:05:51.868
Well, I would say in the state of ...

1040
01:05:51.868 --> 01:05:54.239
Missouri, there are a few streams that.

1041
01:05:54.240 --> 01:05:56.851
There's no stream that has more macrovertebrate data ...

1042
01:05:56.851 --> 01:05:58.359
collected than Houston Creek.

1043
01:06:01.000 --> 01:06:01.602
So, yeah,

1044
01:06:01.602 --> 01:06:03.559
it's a really unique endeavor.

1045
01:06:03.760 --> 01:06:05.160
I think it's worthwhile.

1046
01:06:05.320 --> 01:06:09.065
I think collecting some additional data that we did ...

1047
01:06:09.065 --> 01:06:12.374
during the winter season provided us a better ...

1048
01:06:12.374 --> 01:06:16.119
understanding of some impacts to water chemistry.

1049
01:06:16.280 --> 01:06:17.360
But it also.

1050
01:06:18.040 --> 01:06:21.133
Some of that information is available in literature,

1051
01:06:21.133 --> 01:06:25.119
but as I mentioned earlier, not all the data were publicly available.

1052
01:06:25.200 --> 01:06:28.361
I think over time, as publications are released,

1053
01:06:28.361 --> 01:06:30.519
more data will become available.

1054
01:06:30.920 --> 01:06:35.880
So all the metrics that were calculated from the inbert community.

1055
01:06:36.000 --> 01:06:38.920
Samples are provided to the Camden.

1056
01:06:39.000 --> 01:06:43.260
So I believe the science team will talk a bit more about their ...

1057
01:06:43.260 --> 01:06:46.839
priorities and projects and future discussions.

1058
01:06:46.960 --> 01:06:49.400
And this study.

1059
01:06:49.560 --> 01:06:52.881
Information from this has not reshaped,

1060
01:06:52.881 --> 01:06:57.667
but either reconfigured a few of their priorities to aid in ...

1061
01:06:57.667 --> 01:07:03.039
understanding what is impacting the Hinkson Creek aquatic life.

1062
01:07:06.040 --> 01:07:07.000
Thank you.

1063
01:07:13.840 --> 01:07:15.536
All right, does anyone else have any ...

1064
01:07:15.536 --> 01:07:17.119
questions they would like to ask?

1065
01:07:19.400 --> 01:07:20.299
Hey, Michele,

1066
01:07:20.299 --> 01:07:21.198
it's Amy again.

1067
01:07:23.360 --> 01:07:25.240
All right, I'll turn my camera back on.

1068
01:07:25.760 --> 01:07:30.037
I'm also curious about stone flies within the Hinkson ...

1069
01:07:30.037 --> 01:07:35.359
watershed and what kind of diversity we have there in recent years.

1070
01:07:35.480 --> 01:07:38.698
We've historically, in the past,

1071
01:07:38.698 --> 01:07:43.525
had some pretty good diversity within the perlady ...

1072
01:07:43.525 --> 01:07:47.318
family, but have we seen much recently?

1073
01:07:47.760 --> 01:07:53.960
And I don't think I caught that in Cody's talk.

1074
01:07:54.760 --> 01:07:56.200
If there were a.

1075
01:07:56.280 --> 01:07:59.280
Because stoneflies are like kind of the most.

1076
01:07:59.800 --> 01:08:00.705
Well, of course,

1077
01:08:00.705 --> 01:08:03.550
the most sensitive and the ones that we really want to ...

1078
01:08:03.550 --> 01:08:06.718
educate are volunteers within the stream team program on.

1079
01:08:06.840 --> 01:08:10.076
So I wanted to learn if we actually still have a stonefly ...

1080
01:08:10.076 --> 01:08:12.679
population within the Hinkson watershed.

1081
01:08:14.520 --> 01:08:16.320
You want me to do that?  Yeah, go ahead.

1082
01:08:16.960 --> 01:08:17.720
Yes.

1083
01:08:19.600 --> 01:08:26.160
It's a limited population, certainly in terms of richness.

1084
01:08:28.280 --> 01:08:30.610
I remember, I think they got perlusta,

1085
01:08:30.610 --> 01:08:32.284
neoperla, and I don't know,

1086
01:08:32.284 --> 01:08:33.958
you know, there might have.

1087
01:08:34.880 --> 01:08:38.960
There were a few perlids that you had mentioned, but.

1088
01:08:39.040 --> 01:08:41.960
But stone flies, unfortunately, are just not.

1089
01:08:44.240 --> 01:08:50.040
They're not very abundant or diverse in Hinkson Creek.

1090
01:08:50.160 --> 01:08:55.349
So they're probably, other than perhaps Perlista,

1091
01:08:55.349 --> 01:09:00.779
they would be pretty difficult to get some meaningful ...

1092
01:09:00.779 --> 01:09:06.330
patterns doing any kind of rapid bioassessment or just ...

1093
01:09:06.330 --> 01:09:11.278
bioassessment work that focused on stoneflies.

1094
01:09:13.560 --> 01:09:15.942
Cody, do you think that there's still ...

1095
01:09:15.942 --> 01:09:19.785
a possibility that some of the tributaries to Hinkson Creek ...

1096
01:09:19.785 --> 01:09:22.398
might still have stonefly populations?

1097
01:09:23.200 --> 01:09:25.586
It just depends on the year and whether or not,

1098
01:09:25.586 --> 01:09:27.219
you know, because some of these ...

1099
01:09:27.219 --> 01:09:30.296
tributaries in Hinkson Creek are going to lack flow during ...

1100
01:09:30.296 --> 01:09:31.677
certain times of the year.

1101
01:09:31.680 --> 01:09:33.960
So it's just going to depend on year to year conditions.

1102
01:09:36.560 --> 01:09:39.560
Okay, thank you, David.

1103
01:09:39.640 --> 01:09:43.160
I assume that's my friend David Kharani has got some questions.

1104
01:09:43.600 --> 01:09:48.080
How are we proposing to use the indicator metrics going forward?

1105
01:09:48.720 --> 01:09:51.201
That is really up to the cam, David,

1106
01:09:51.201 --> 01:09:54.879
the metrics were determined based on our analysis.

1107
01:09:55.840 --> 01:09:59.576
We came up with a systematic approach to derive ...

1108
01:09:59.576 --> 01:10:02.833
those metrics, and some of the metrics do ...

1109
01:10:02.833 --> 01:10:06.857
overlap with the Missouri stream condition index ...

1110
01:10:06.857 --> 01:10:08.198
metrics such as.

1111
01:10:08.520 --> 01:10:10.280
Sam, do you have that in front of you?

1112
01:10:10.440 --> 01:10:11.840
I can get it quickly.

1113
01:10:14.240 --> 01:10:17.760
I'll let Sam fill you in on the indicator metrics that were.

1114
01:10:19.200 --> 01:10:21.080
Yeah, the indicator metrics.

1115
01:10:21.240 --> 01:10:24.363
Two of them are the same as are used in the Missouri ...

1116
01:10:24.363 --> 01:10:27.867
stream condition index, and that's total tax richness ...

1117
01:10:27.867 --> 01:10:29.238
and ePT tax richness.

1118
01:10:30.160 --> 01:10:35.252
Three others that were in this study pretty effective at ...

1119
01:10:35.252 --> 01:10:40.236
distinguishing impaired versus less impaired stream ...

1120
01:10:40.236 --> 01:10:44.028
segments were clinger climber richness,

1121
01:10:44.028 --> 01:10:49.878
percent intolerant taxa and the ratio of scrapers to filterers.

1122
01:10:50.080 --> 01:10:54.056
And none of them were perfect,

1123
01:10:54.056 --> 01:10:56.759
but all of them were.

1124
01:10:56.880 --> 01:11:00.641
They had the qualities that we liked in terms of indicator ...

1125
01:11:00.641 --> 01:11:02.599
metrics because they varied.

1126
01:11:02.640 --> 01:11:03.960
Overdose.

1127
01:11:04.040 --> 01:11:06.459
Large gradients or fairly large gradients,

1128
01:11:06.459 --> 01:11:08.159
instead of, you know, like the.

1129
01:11:09.280 --> 01:11:13.367
Some of the indices, the sediment tolerance index ...

1130
01:11:13.367 --> 01:11:15.799
only varies from one to three.

1131
01:11:15.880 --> 01:11:20.200
So it's pretty difficult to get, you know, much of a.

1132
01:11:20.280 --> 01:11:23.160
You really have to anyway, you know what I'm saying?

1133
01:11:23.320 --> 01:11:27.520
And the diversity index varies over a very small range too.

1134
01:11:27.640 --> 01:11:31.741
And some of the other just taxonomically related to ...

1135
01:11:31.741 --> 01:11:35.270
metrics also, they just vary over such small ...

1136
01:11:35.270 --> 01:11:40.420
ranges that they're difficult to really interpret a difference ...

1137
01:11:40.420 --> 01:11:43.758
between two sites or even two study areas.

1138
01:11:44.080 --> 01:11:47.429
So we were looking for ones that varied over large ...

1139
01:11:47.429 --> 01:11:51.024
gradients and that were consistently showed a clear ...

1140
01:11:51.024 --> 01:11:53.883
difference between the disturbed areas,

1141
01:11:53.883 --> 01:11:57.396
which in this case was the urban segment of Hinkson,

1142
01:11:57.396 --> 01:12:01.317
and the less disturbed areas, which were the other three.

1143
01:12:01.520 --> 01:12:05.391
And then lastly, we wanted metrics that were ...

1144
01:12:05.391 --> 01:12:10.309
associated with either pollution related degradation ...

1145
01:12:10.309 --> 01:12:13.239
or habitat related degradation.

1146
01:12:14.360 --> 01:12:17.720
And that's all it's identified in the report.

1147
01:12:25.200 --> 01:12:29.197
This is Rob Jacobson again, and I'll preface this by saying ...

1148
01:12:29.197 --> 01:12:31.725
that in any kind of project like this,

1149
01:12:31.725 --> 01:12:35.314
there's always a concern about the costs that go into ...

1150
01:12:35.314 --> 01:12:39.718
the science relative to the costs that go into fixing the system.

1151
01:12:39.920 --> 01:12:43.478
And one of the things that I think has come out of this ...

1152
01:12:43.478 --> 01:12:46.788
data mining report is an understanding of those ...

1153
01:12:46.788 --> 01:12:50.429
metrics that might be more cost effective in terms of ...

1154
01:12:50.429 --> 01:12:53.159
tracking the health of Hinkson Creek.

1155
01:12:53.320 --> 01:12:57.733
I don't think that means that the Missouri stream condition ...

1156
01:12:57.733 --> 01:13:00.999
index sampling can be abandoned eventually ...

1157
01:13:00.999 --> 01:13:03.559
because I think that's necessary.

1158
01:13:03.600 --> 01:13:05.800
And Tim can tell me if I'm wrong about this.

1159
01:13:06.000 --> 01:13:10.440
I think that's necessary to get pinks and creek off the impaired list.

1160
01:13:10.600 --> 01:13:14.199
But in terms of narrowing down what we think is really ...

1161
01:13:14.199 --> 01:13:17.553
going on in trying to figure out what the most cost ...

1162
01:13:17.553 --> 01:13:21.152
effective mitigation is, some of these metrics from ...

1163
01:13:21.152 --> 01:13:25.160
this data mining report might be very helpful to do that in a ...

1164
01:13:25.160 --> 01:13:26.877
cost effective way over.

1165
01:13:28.760 --> 01:13:29.760
Well, that's true.

1166
01:13:29.880 --> 01:13:33.873
And they can also be, those metrics can be ...

1167
01:13:33.873 --> 01:13:39.159
calculated regardless of the sampling methodology.

1168
01:13:39.520 --> 01:13:41.779
So if they're, you know,

1169
01:13:41.779 --> 01:13:44.941
you can, you don't have to abandon ...

1170
01:13:44.941 --> 01:13:49.798
the historical methodology to supplement it with,

1171
01:13:49.798 --> 01:13:53.638
you know, with new types of collections.

1172
01:13:56.640 --> 01:13:57.114
So, Sam,

1173
01:13:57.114 --> 01:13:59.149
for example, because there's such a ...

1174
01:13:59.149 --> 01:14:01.659
difference between the spring and the fall,

1175
01:14:01.659 --> 01:14:04.237
potentially just drop all the fall sampling.

1176
01:14:04.400 --> 01:14:05.840
What would you think about that?

1177
01:14:06.000 --> 01:14:08.480
Well, you know, that's.

1178
01:14:08.640 --> 01:14:12.637
I think it would be, I can certainly see the ...

1179
01:14:12.637 --> 01:14:16.519
argument of dropping one of the seasons.

1180
01:14:17.600 --> 01:14:21.984
The problem with the spring sampling is that it's so ...

1181
01:14:21.984 --> 01:14:25.043
variable, and a lot of that is tied to ...

1182
01:14:25.043 --> 01:14:29.326
natural reasons, which is just the life histories ...

1183
01:14:29.326 --> 01:14:33.099
of the really common and abundant tax event,

1184
01:14:33.099 --> 01:14:36.056
and also the physical conditions,

1185
01:14:36.056 --> 01:14:40.033
the flow conditions, which are generally more ...

1186
01:14:40.033 --> 01:14:43.398
variable in the spring than in the fall.

1187
01:14:43.560 --> 01:14:48.108
So I kind of like the fall samples because they ...

1188
01:14:48.108 --> 01:14:51.459
accentuate in a lot of cases, the,

1189
01:14:51.459 --> 01:14:53.972
except, unfortunately,

1190
01:14:53.972 --> 01:14:58.041
except for probably the chloride issue,

1191
01:14:58.041 --> 01:15:03.666
they accentuate the other potential stream impairment ...

1192
01:15:03.666 --> 01:15:08.573
factors because they have a chance to act over the ...

1193
01:15:08.573 --> 01:15:11.206
summer over low, you know,

1194
01:15:11.206 --> 01:15:14.916
during low, stable flow conditions.

1195
01:15:25.040 --> 01:15:27.343
I have a comment to add to that,

1196
01:15:27.343 --> 01:15:28.264
Sam, maybe,

1197
01:15:28.264 --> 01:15:30.935
you know, just to add to what you're ...

1198
01:15:30.935 --> 01:15:34.251
saying there, we've always considered the ...

1199
01:15:34.251 --> 01:15:38.581
fall sampling a good indicator of how well or how good the ...

1200
01:15:38.581 --> 01:15:42.266
potential is of a stream to recover if it has been ...

1201
01:15:42.266 --> 01:15:46.411
stressed from any of the wintertime stresses that you ...

1202
01:15:46.411 --> 01:15:50.556
would be seeing the effects of in the spring sampling.

1203
01:15:50.640 --> 01:15:52.822
So, and we saw this over there in ...

1204
01:15:52.822 --> 01:15:55.760
the Kansas City streams pretty commonly,

1205
01:15:55.760 --> 01:15:58.446
is that I, is that you could kind of tell ...

1206
01:15:58.446 --> 01:16:02.224
which ones had a better potential to be able to recover ...

1207
01:16:02.224 --> 01:16:06.757
from those winter stresses by looking at the fall sampling data.

1208
01:16:06.960 --> 01:16:10.323
And so that is one thing it does kind of help out with,

1209
01:16:10.323 --> 01:16:14.155
is that it does give you that, give you an indication of that ...

1210
01:16:14.155 --> 01:16:15.719
potential of recovery.

1211
01:16:16.840 --> 01:16:18.720
Well, that's a good point, and I agree.

1212
01:16:21.040 --> 01:16:21.622
Hey, Barry,

1213
01:16:21.622 --> 01:16:23.079
could you identify yourself?

1214
01:16:25.440 --> 01:16:28.464
Yeah, this is Barry Poulton from ...

1215
01:16:28.464 --> 01:16:31.600
USGS, and I'm on the science team.

1216
01:16:34.240 --> 01:16:35.720
It's good to hear you, Barry.

1217
01:16:38.600 --> 01:16:40.960
All right, David has another question.

1218
01:16:41.120 --> 01:16:45.200
What about focusing more sampling effort on fewer sites?

1219
01:16:45.600 --> 01:16:48.120
Is there anything in the data to support that?

1220
01:16:49.480 --> 01:16:51.760
You have any add to that?

1221
01:16:52.760 --> 01:16:56.117
Well, I think it's always,

1222
01:16:56.117 --> 01:17:02.679
there's always going to be a balance of what to trim.

1223
01:17:04.240 --> 01:17:08.841
And that's one of those things that I would leave to ...

1224
01:17:08.841 --> 01:17:13.004
the science team or whoever that they put that ...

1225
01:17:13.004 --> 01:17:16.838
responsibility on to make that decision.

1226
01:17:16.960 --> 01:17:18.217
I mean, it's,

1227
01:17:18.217 --> 01:17:21.647
you know, you're always walking the ...

1228
01:17:21.647 --> 01:17:24.505
tightrope between, you know,

1229
01:17:24.505 --> 01:17:28.278
the cost and the possible information.

1230
01:17:29.240 --> 01:17:31.342
I would like to add to that, Sam,

1231
01:17:31.342 --> 01:17:34.090
that in the Hinkson Creek rural segment,

1232
01:17:34.090 --> 01:17:36.838
we have eight, seven and 6.5 frequently.

1233
01:17:36.920 --> 01:17:42.040
Sites eight and seven are non flowing for part of the year.

1234
01:17:42.480 --> 01:17:48.680
But 6.5 has still been a good comparable location to seven and eight.

1235
01:17:48.720 --> 01:17:50.908
So there's advantageous, you know,

1236
01:17:50.908 --> 01:17:53.679
to eliminating a couple in the rural segment.

1237
01:17:58.280 --> 01:18:00.080
This is Rob Jacobson again.

1238
01:18:00.280 --> 01:18:04.056
So what about sites one and two that we know are affected ...

1239
01:18:04.056 --> 01:18:07.339
by different processes through backwater from ...

1240
01:18:07.339 --> 01:18:09.719
Missouri river over those should.

1241
01:18:09.800 --> 01:18:13.296
Those should really be assessed other candidate ...

1242
01:18:13.296 --> 01:18:17.303
reference or control streams because we don't have that ...

1243
01:18:17.303 --> 01:18:20.117
information, that database from DNR to ...

1244
01:18:20.117 --> 01:18:23.783
understand how those backwater conditions impact ...

1245
01:18:23.783 --> 01:18:25.317
community assembly.

1246
01:18:27.200 --> 01:18:31.277
Right. And if I interpreted what you ...

1247
01:18:31.277 --> 01:18:33.723
were, what you meant,

1248
01:18:33.723 --> 01:18:35.082
Rob, it was,

1249
01:18:35.082 --> 01:18:41.741
is it valid to include those and compare them against other ...

1250
01:18:41.741 --> 01:18:48.672
sites that don't have the river influence and that don't have ...

1251
01:18:48.672 --> 01:18:51.118
comparable habitat?

1252
01:18:51.160 --> 01:18:52.480
And that's a good question.

1253
01:18:53.080 --> 01:19:01.920
That's for the science team and the regulators to make the call on.

1254
01:19:02.040 --> 01:19:06.160
But I certainly see what you're getting at.

1255
01:19:07.680 --> 01:19:08.800
And I would just.

1256
01:19:09.360 --> 01:19:10.345
Go ahead. No,

1257
01:19:10.345 --> 01:19:11.599
so go ahead, Rob.

1258
01:19:12.480 --> 01:19:13.224
Okay. Well,

1259
01:19:13.224 --> 01:19:16.576
I was just going to add that the science team discussed ...

1260
01:19:16.576 --> 01:19:19.257
with the DNR quite a bit about defining a new ...

1261
01:19:19.257 --> 01:19:20.597
segment downstream.

1262
01:19:20.720 --> 01:19:28.920
And the regulatory difficulty in doing that was extreme.

1263
01:19:29.200 --> 01:19:30.720
But that's, you know,

1264
01:19:30.720 --> 01:19:33.000
for the stream condition index.

1265
01:19:33.120 --> 01:19:36.519
If we're talking about the partners wanting to do a ...

1266
01:19:36.519 --> 01:19:39.514
better job of pinning down what the source of ...

1267
01:19:39.514 --> 01:19:43.318
impairment is, maybe those sites could be dropped over.

1268
01:19:44.800 --> 01:19:47.330
Rob, I was just going to add that ...

1269
01:19:47.330 --> 01:19:52.002
the reference streams are located in a position that they ...

1270
01:19:52.002 --> 01:19:56.479
are not impacted by any backwater from Missouri river.

1271
01:20:03.720 --> 01:20:05.320
And I do agree with DNR.

1272
01:20:05.400 --> 01:20:10.360
It does take a long time to develop and assess criteria ...

1273
01:20:10.360 --> 01:20:14.439
for unique habitats and unique situations.

1274
01:20:14.640 --> 01:20:17.760
Because ultimately DNR not only answers to.

1275
01:20:18.080 --> 01:20:22.315
They have to answer to EPA and EPA has to approve that ...

1276
01:20:22.315 --> 01:20:24.679
methodology alongside DNR.

1277
01:20:33.720 --> 01:20:35.280
I had one more quick question.

1278
01:20:35.320 --> 01:20:38.767
This is Erin, and I saw it in the scatter ...

1279
01:20:38.767 --> 01:20:41.891
plot, but I don't know if you really ...

1280
01:20:41.891 --> 01:20:45.122
talked about it, and this is maybe an ...

1281
01:20:45.122 --> 01:20:49.754
anecdotal thing that I've noticed in the data in the ...

1282
01:20:49.754 --> 01:20:52.985
past, is that it seems like our misci ...

1283
01:20:52.985 --> 01:20:56.540
scores are better when you've sampled,

1284
01:20:56.540 --> 01:21:00.525
when we've recently related to a flow event,

1285
01:21:00.525 --> 01:21:02.356
to a rainfall event.

1286
01:21:04.360 --> 01:21:08.240
Would you say that this data kind of bears that out or.

1287
01:21:08.320 --> 01:21:09.560
Not necessarily?

1288
01:21:10.320 --> 01:21:13.260
Erin, there were some indications ...

1289
01:21:13.260 --> 01:21:18.063
based on the correlation with the physical data at station ...

1290
01:21:18.063 --> 01:21:22.179
3.5 where we had flow information that median flow ...

1291
01:21:22.179 --> 01:21:25.119
positively related to percent EPT,

1292
01:21:25.119 --> 01:21:28.353
percent EP, percent ephemeroptera EPT ...

1293
01:21:28.353 --> 01:21:31.979
to chironomid ratio, percent slow seasonal ...

1294
01:21:31.979 --> 01:21:35.115
development, percent rare and drift.

1295
01:21:35.200 --> 01:21:37.929
So the higher the median flow,

1296
01:21:37.929 --> 01:21:43.279
the higher the values for those important taxicab groups.

1297
01:21:44.560 --> 01:21:48.370
But on the contrary, minimum flow was positive ...

1298
01:21:48.370 --> 01:21:49.640
related to Ept.

1299
01:21:49.680 --> 01:21:51.744
Richness, ephemeropta richness,

1300
01:21:51.744 --> 01:21:53.239
clear climber richness.

1301
01:21:53.280 --> 01:21:58.520
So there's some back and forth with flow from the flow data we had.

1302
01:22:01.520 --> 01:22:02.202
So, Erin,

1303
01:22:02.202 --> 01:22:03.719
this is Paul Blanchard.

1304
01:22:04.840 --> 01:22:08.772
Some of the poking around of the data that I've done,

1305
01:22:08.772 --> 01:22:13.253
I would say there's definitely not a clear indication that ...

1306
01:22:13.253 --> 01:22:17.002
really high flow events are the dominant cause of ...

1307
01:22:17.002 --> 01:22:19.379
issues, but we have all sorts of ...

1308
01:22:19.379 --> 01:22:23.860
different sized pulses that could be bringing in all sorts ...

1309
01:22:23.860 --> 01:22:26.603
of things, whether it's sediment or ...

1310
01:22:26.603 --> 01:22:28.797
chemicals of various sorts.

1311
01:22:28.880 --> 01:22:34.480
So there's not a clear indication of a flow effect that I would say.

1312
01:22:39.760 --> 01:22:40.647
Oh, yeah.

1313
01:22:40.647 --> 01:22:42.199
Okay, thank you.

1314
01:22:42.400 --> 01:22:43.600
And Erin, this is Sam.

1315
01:22:43.640 --> 01:22:46.803
Again, flow is one of those variables ...

1316
01:22:46.803 --> 01:22:51.088
that we alluded to that is really kind of a neutral,

1317
01:22:51.088 --> 01:22:52.618
or it's, you know,

1318
01:22:52.618 --> 01:22:55.781
there is a range kind of in the middle,

1319
01:22:55.781 --> 01:22:57.923
so to speak, that is good,

1320
01:22:57.923 --> 01:23:00.576
and on either end of that range,

1321
01:23:00.576 --> 01:23:01.596
it's bad. I.

1322
01:23:01.640 --> 01:23:06.102
So it doesn't lend itself well to correlation analyses and ...

1323
01:23:06.102 --> 01:23:08.287
analyses like the, you know,

1324
01:23:08.287 --> 01:23:11.838
that are included in the ordination analysis.

1325
01:23:12.400 --> 01:23:16.450
And that's probably partly why we get some ...

1326
01:23:16.450 --> 01:23:18.880
contradictory results.

1327
01:23:20.320 --> 01:23:22.627
Yeah, I guess part of my question ...

1328
01:23:22.627 --> 01:23:23.567
is, you know,

1329
01:23:23.567 --> 01:23:27.412
we only sampled once in the spring and once in the fall,

1330
01:23:27.412 --> 01:23:29.377
and it was kind of, you know,

1331
01:23:29.377 --> 01:23:33.308
whenever it got scheduled, and sometimes it was before ...

1332
01:23:33.308 --> 01:23:35.957
a rain, sometimes it was after a rain.

1333
01:23:36.320 --> 01:23:37.365
And, you know,

1334
01:23:37.365 --> 01:23:41.633
I guess that's part of the statistical analysis piece that ...

1335
01:23:41.633 --> 01:23:43.898
maybe I don't understand, but,

1336
01:23:43.898 --> 01:23:46.598
you know, I'm just trying to put some.

1337
01:23:48.200 --> 01:23:50.240
Just trying to understand it, I guess.

1338
01:23:50.640 --> 01:23:52.676
Erin, we did look at flow ...

1339
01:23:52.676 --> 01:23:57.330
information from 3.5 that included basically pulses or,

1340
01:23:57.330 --> 01:24:00.336
like events, like high water events,

1341
01:24:00.336 --> 01:24:04.020
because that's the only station we have true,

1342
01:24:04.020 --> 01:24:06.929
meaningful flow information from,

1343
01:24:06.929 --> 01:24:09.838
unless more data become available.

1344
01:24:10.320 --> 01:24:16.040
And there weren't any correlations between the flow ...

1345
01:24:16.040 --> 01:24:19.810
pulses and the community metrics,

1346
01:24:19.810 --> 01:24:25.530
but literature very frequently has indicated that,

1347
01:24:25.530 --> 01:24:31.640
that those do have an effect on biological communities.

1348
01:24:31.800 --> 01:24:33.800
So even though.

1349
01:24:33.920 --> 01:24:36.494
And I mean, this is something that you ...

1350
01:24:36.494 --> 01:24:39.899
really have to wrestle with in any field studies,

1351
01:24:39.899 --> 01:24:42.972
even though we know or strongly suspect that ...

1352
01:24:42.972 --> 01:24:45.131
something is having an effect,

1353
01:24:45.131 --> 01:24:46.958
our data may not show that.

1354
01:24:47.040 --> 01:24:51.240
And I think that happened pretty frequently with Hinkson Creek data.

1355
01:24:51.760 --> 01:24:52.640
Right. Yeah,

1356
01:24:52.640 --> 01:24:55.600
I could see where a really large event could,

1357
01:24:55.600 --> 01:24:58.000
you know, wash macroinvertebrates ...

1358
01:24:58.000 --> 01:25:00.320
down or wash more pollutants down.

1359
01:25:01.200 --> 01:25:03.627
And I think I get the point where,

1360
01:25:03.627 --> 01:25:06.504
you know, there's kind of a median flow ...

1361
01:25:06.504 --> 01:25:10.640
that's beneficial and then too much or too little is not ...

1362
01:25:10.640 --> 01:25:13.157
necessarily exactly right. Yep.

1363
01:25:15.760 --> 01:25:18.494
And then I know we're close on time,

1364
01:25:18.494 --> 01:25:22.642
but I didn't know if any of the stakeholders wanted to ...

1365
01:25:22.642 --> 01:25:26.224
comment on just quick thoughts on all of this,

1366
01:25:26.224 --> 01:25:28.958
like ideas of where we need to head.

1367
01:25:40.320 --> 01:25:41.711
Well, this is Todd from the ...

1368
01:25:41.711 --> 01:25:43.039
University of Missouri.

1369
01:25:44.040 --> 01:25:46.674
As far as I'm concerned, where we need to head is ...

1370
01:25:46.674 --> 01:25:49.308
where the science team tells me we need to head,

1371
01:25:49.308 --> 01:25:50.929
because this is, once again,

1372
01:25:50.929 --> 01:25:52.077
really not my field.

1373
01:25:59.360 --> 01:26:02.240
This is Amy Meyer from the Missouri stream team program.

1374
01:26:02.360 --> 01:26:06.840
And we are not alone in handling this kind of issue.

1375
01:26:06.960 --> 01:26:10.680
So this is something that is happening everywhere.

1376
01:26:10.880 --> 01:26:15.944
And if we can maybe get the opinions of folks from other ...

1377
01:26:15.944 --> 01:26:19.770
states and other types of topographies,

1378
01:26:19.770 --> 01:26:22.358
maybe we can work together.

1379
01:26:29.200 --> 01:26:30.560
Go ahead, Cody.  I'm sorry.

1380
01:26:30.680 --> 01:26:31.905
Oh, I was just going to make the ...

1381
01:26:31.905 --> 01:26:32.640
general comment.

1382
01:26:32.800 --> 01:26:34.404
I've been in, you know,

1383
01:26:34.404 --> 01:26:36.599
Hinkson Creek numerous times.

1384
01:26:36.680 --> 01:26:40.441
I've been in other urban streams throughout Missouri,

1385
01:26:40.441 --> 01:26:43.957
throughout the country, and urban Hinkson Creek is ...

1386
01:26:43.957 --> 01:26:45.919
a fantastic urban strength.

1387
01:26:46.400 --> 01:26:49.520
The riparian corridors are well preserved.

1388
01:26:49.920 --> 01:26:53.196
Point sources from a continuous discharge ...

1389
01:26:53.196 --> 01:26:56.199
perspective have all been eliminated.

1390
01:26:56.320 --> 01:26:59.920
The city's done great work eliminating small systems ...

1391
01:26:59.920 --> 01:27:02.320
and condensing to a regional sewer.

1392
01:27:02.440 --> 01:27:05.720
So Hinkson Creek is a fantastic urban stream.

1393
01:27:05.760 --> 01:27:09.600
It's just not quite up to par with the reference condition.

1394
01:27:09.760 --> 01:27:12.472
But the city, the county university have ...

1395
01:27:12.472 --> 01:27:16.221
nothing to do or have should be patting themselves on the ...

1396
01:27:16.221 --> 01:27:19.890
back with everything that they've undertaken over the ...

1397
01:27:19.890 --> 01:27:23.399
last year or the last years to improve Hinkson Creek.

1398
01:27:25.000 --> 01:27:27.380
Oh, it's an awesome stream to ...

1399
01:27:27.380 --> 01:27:29.959
float in the right water level.

1400
01:27:30.080 --> 01:27:32.760
So I highly recommend it.  It's awesome.

1401
01:27:36.200 --> 01:27:39.008
Yeah. So considerations of what ...

1402
01:27:39.008 --> 01:27:41.400
could be done, and the city,

1403
01:27:41.400 --> 01:27:46.288
county and university have already done quite a bit with ...

1404
01:27:46.288 --> 01:27:49.200
respect to improving the stream.

1405
01:27:49.280 --> 01:27:54.800
So we will have more to say about chlorides in the next study.

1406
01:27:54.960 --> 01:27:57.160
I mean, obviously that is something ...

1407
01:27:57.160 --> 01:27:58.920
that seems to stand out here.

1408
01:27:58.960 --> 01:28:01.727
We don't think, and speaking for the science ...

1409
01:28:01.727 --> 01:28:03.597
team, it would please others,

1410
01:28:03.597 --> 01:28:06.888
speak up because we have a lack of data or some of those ...

1411
01:28:06.888 --> 01:28:08.758
data are very hard to collect.

1412
01:28:08.840 --> 01:28:10.800
We don't think it's the only issue.

1413
01:28:12.560 --> 01:28:17.048
But you do have some things to work with and potentially ...

1414
01:28:17.048 --> 01:28:18.999
consider in the future.

1415
01:28:19.600 --> 01:28:20.360
Over.

1416
01:28:24.520 --> 01:28:26.520
Hey, Tim, it's Amy here.

1417
01:28:27.200 --> 01:28:32.493
So of course I'm recommending recreational ...

1418
01:28:32.493 --> 01:28:34.639
use of the stream.

1419
01:28:34.720 --> 01:28:38.000
So what do you feel about that?

1420
01:28:38.160 --> 01:28:42.060
Even though this is kind of like the science type of ...

1421
01:28:42.060 --> 01:28:45.496
organization that we're doing here with the ...

1422
01:28:45.496 --> 01:28:48.839
macroinvertebrates and the science data,

1423
01:28:48.839 --> 01:28:51.439
do you have any recommendations?

1424
01:28:52.720 --> 01:28:55.240
I'm not quite sure what you're getting at.  Amyde.

1425
01:28:55.720 --> 01:28:57.020
Well, mostly like,

1426
01:28:57.020 --> 01:28:58.807
well, how do you feel about ...

1427
01:28:58.807 --> 01:29:00.838
recreating on Hinkson creek?

1428
01:29:03.000 --> 01:29:04.240
In what respect?

1429
01:29:04.320 --> 01:29:06.120
You mean floating fishing?

1430
01:29:06.280 --> 01:29:07.680
Yes, all of it.

1431
01:29:08.400 --> 01:29:10.000
How do I feel?

1432
01:29:10.160 --> 01:29:11.391
Yeah, I mean,

1433
01:29:11.391 --> 01:29:15.644
I would float it, if that's what you're asking ...

1434
01:29:15.644 --> 01:29:18.666
me, but certainly not an extreme ...

1435
01:29:18.666 --> 01:29:23.703
high flow sense because you have to ride the pulse down ...

1436
01:29:23.703 --> 01:29:25.158
in this stream.

1437
01:29:26.520 --> 01:29:30.143
Right. So I guess what I'm getting at ...

1438
01:29:30.143 --> 01:29:35.215
is wanting to improve the stream so that we get more ...

1439
01:29:35.215 --> 01:29:39.079
recreational activity on the stream.

1440
01:29:40.800 --> 01:29:42.160
Ah, I see.

1441
01:29:42.360 --> 01:29:45.520
Yeah, and there's.

1442
01:29:45.600 --> 01:29:47.240
And it is very.

1443
01:29:48.880 --> 01:29:51.318
Yeah, there's a lot happening on ...

1444
01:29:51.318 --> 01:29:54.839
the stream and I think we're on the right track.

1445
01:29:56.800 --> 01:29:57.382
So, Amy,

1446
01:29:57.382 --> 01:29:58.879
this is Rob Jacobson.

1447
01:29:59.000 --> 01:30:03.129
In the science strategy report, there is a section talking ...

1448
01:30:03.129 --> 01:30:07.679
about stakeholder views of Hinkson Creek and how they value it.

1449
01:30:07.680 --> 01:30:10.233
The studies were done a while ago and we said that ...

1450
01:30:10.233 --> 01:30:13.679
might be time to redo that study to come up with that information.

1451
01:30:14.720 --> 01:30:18.120
The cam process does not deal with bacteria,

1452
01:30:18.120 --> 01:30:21.520
but it is another concern on Hinkson Creek.

1453
01:30:21.840 --> 01:30:26.182
I fish it and wait it and I floated it and I'm just careful ...

1454
01:30:26.182 --> 01:30:28.919
not to get anything in my eyes over.

1455
01:30:29.920 --> 01:30:31.596
Yeah, I was going to bring up the ...

1456
01:30:31.596 --> 01:30:33.594
same thing with respect to, you know,

1457
01:30:33.594 --> 01:30:35.399
any urban stream for that matter.

1458
01:30:38.720 --> 01:30:43.941
So I guess maybe my angle would be to recreate in your ...

1459
01:30:43.941 --> 01:30:48.919
local urban stream and be as careful as possible.

1460
01:30:51.040 --> 01:30:52.880
Sure, absolutely.

1461
01:30:53.960 --> 01:30:56.920
This is Barry Poulton from the science team.

1462
01:30:57.040 --> 01:30:58.560
I do want to comment on that.

1463
01:30:58.600 --> 01:31:04.010
I think one of the studies that we had really hoped might to ...

1464
01:31:04.010 --> 01:31:08.406
be of some interest, and I think we still have it ...

1465
01:31:08.406 --> 01:31:13.027
down as one of the studies that was rated among our ...

1466
01:31:13.027 --> 01:31:17.987
recommendations as the science team is to look at the ...

1467
01:31:17.987 --> 01:31:20.467
fish, the fish community,

1468
01:31:20.467 --> 01:31:25.877
and in particular look at the sportfish populations that ...

1469
01:31:25.877 --> 01:31:30.837
Hinkson Creek has in hopes that it would eventually ...

1470
01:31:30.837 --> 01:31:35.797
increase awareness amongst the public and so forth.

1471
01:31:35.840 --> 01:31:40.288
It kind of highlights the fact there are other recreational ...

1472
01:31:40.288 --> 01:31:44.291
uses that Kingston Creek could be used for besides the ...

1473
01:31:44.291 --> 01:31:48.027
typical ones that people can really see real well,

1474
01:31:48.027 --> 01:31:50.518
like the bike trails and so forth.

1475
01:31:50.640 --> 01:31:54.746
And so that was one of the things I had really hoped for,

1476
01:31:54.746 --> 01:31:58.030
was that if we had some fish community data,

1477
01:31:58.030 --> 01:32:01.406
we might not be able to necessarily use it for ...

1478
01:32:01.406 --> 01:32:03.139
evaluating, you know,

1479
01:32:03.139 --> 01:32:05.693
the stream quality quite as much,

1480
01:32:05.693 --> 01:32:09.525
even though that hat is being used in other places,

1481
01:32:09.525 --> 01:32:12.992
but also the awareness of other recreational ...

1482
01:32:12.992 --> 01:32:16.915
opportunities that maybe aren't so obvious to the,

1483
01:32:16.915 --> 01:32:19.196
you know, to the average user.

1484
01:32:22.960 --> 01:32:24.491
Yeah, this is Carl Scala.

1485
01:32:24.491 --> 01:32:25.439
Can you hear me?

1486
01:32:27.640 --> 01:32:28.842
Yes, yes,

1487
01:32:28.842 --> 01:32:32.599
Columbia City Council. I was.

1488
01:32:32.760 --> 01:32:37.244
Of course I'll defer to the science team being on Cam,

1489
01:32:37.244 --> 01:32:41.830
but it seems to me that I was impressed by your slide for ...

1490
01:32:41.830 --> 01:32:46.518
recommendations which suggested about three things.

1491
01:32:46.560 --> 01:32:48.708
I don't have it right in front of me,

1492
01:32:48.708 --> 01:32:52.042
but additional monitoring sites to compare the rural ...

1493
01:32:52.042 --> 01:32:55.746
versus the urban sections the winter road treatment issues ...

1494
01:32:55.746 --> 01:32:59.006
and the improved long term measurement consistency ...

1495
01:32:59.006 --> 01:33:00.117
from year to year.

1496
01:33:00.240 --> 01:33:03.754
I thought those were great recommendations and ...

1497
01:33:03.754 --> 01:33:07.795
something that the Cam team could take to heart and then ...

1498
01:33:07.795 --> 01:33:10.518
defer to the science team for advice.

1499
01:33:10.560 --> 01:33:11.880
So I appreciate it.

1500
01:33:14.440 --> 01:33:15.400
Thank you.

1501
01:33:21.280 --> 01:33:24.257
All right, so unless there's any really ...

1502
01:33:24.257 --> 01:33:28.497
pressing questions at the end might go ahead and our time ...

1503
01:33:28.497 --> 01:33:32.466
and I want to thank Cody and Sam and Tim for presenting ...

1504
01:33:32.466 --> 01:33:36.255
and again I will be sending out this or posting this ...

1505
01:33:36.255 --> 01:33:39.683
recording on the helpingston.org website if ...

1506
01:33:39.683 --> 01:33:42.118
you guys want to refer back to it.

1507
01:33:42.200 --> 01:33:44.522
And we have two more presentations coming up the ...

1508
01:33:44.522 --> 01:33:47.599
following two weeks about chlorides and the science strategy.

1509
01:33:47.640 --> 01:33:51.283
So if you guys are wanting to dig into a little bit more about ...

1510
01:33:51.283 --> 01:33:54.554
what the science team is thinking next steps might be ...

1511
01:33:54.554 --> 01:33:57.825
until then go out and enjoy the Hinkson and if you guys ...

1512
01:33:57.825 --> 01:34:00.799
have any questions please feel free to email me.

1513
01:34:00.960 --> 01:34:02.280
Thank you all for attending.

1514
01:34:03.240 --> 01:34:04.520
Thank you Michele.

1515
01:34:04.680 --> 01:34:06.880
Thanks Michele.  Thanks.  Thank you.
