1 Middle Eel River Initiative: A collaborative approach for ecological studies

2 Stream Habitats

3 41 Watersheds 36,000 stream miles 8 digit HUCs Eel River HUC Indiana Watersheds

4 814 mi 2

5 Stream Monitoring Water chemistry or Stream habitat? Stream biology? Where and when? How clean is clean?

6 Connecting critical upland processes with aquatic ecosystems.

7 Approximate location of Virgin Old- Growth Forest in 1620, 1850, and 1920 Meyer, 1995

8 Cuyahoga river, 1969

9 3,000-6,000 square miles

10 Ecological Impacts: Streams Chemical Physical Biological Temporal Spatial

11 Can changes be detected?

12 Middle Eel River Monitoring Three gage sites Six Tributaries

13

14 Water Sample Collection Grab Samples Time integrated 15 minute data collection – Water temperature – Stream discharge

15 Parameters Water Chemistry – Total Suspended Sediment – Total Phosphorus – Nitrate Biological – QHEI – IBI – Mussel survey – E. coli

17 Upstream Gage 2010

18 Blocher Site

19 Mexico Site

20 Fish and Habitat

21 Dam Research

22 Indiana 1,100 dams and most in poor condition 70 % privately owned

23 North Manchester dam Approximately 3 feet of water

24 Mean IBI Scores above NM dam Exceptional (50-60) Very Good (49-42) Good (41-34) Fair (33-27) Poor (26-17) Very Poor (<17)

25 Mean QHEI Scores above NM dam
