  3. Indiana Watersheds • 41 Watersheds • 36,000 stream miles • 8 digit HUCs • Eel River HUC 05120104

  4. 814 mi2

  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. Water Sample Collection • Grab Samples • Time integrated • 15 minute data collection • Water temperature • Stream discharge

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

  15. Upstream Gage 2010

  16. Blocher Site

  17. Mexico Site

  18. Fish and Habitat

  19. Dam Research

  20. Indiana • 1,100 dams and most in poor condition • 70 % privately owned

  21. North Manchester dam • Approximately 3 feet of water

  22. 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)

  23. Mean QHEI Scores above NM dam

  24. Liberty Mills Site

  25. Liberty Mills

  26. Indiana’s aquatic “dust bowl”

  27. Suspended Sediment

  28. Smallmouth bass Monitoring • SMB nests • Year Class Strength • Growth

  29. Eel River median discharge and SMB nest frequency at North Manchester

  30. SMB nests and TSS

  31. SMB Spine

  34. My Fish!

  35. Figure 2. Mean and standard error of group biomass for smallmouth bass (11mm TL) after 4 d and 7 d exposure to bentonite clay suspensions.

  36. Smallmouth Bass Compared to mean Total Suspended Solids in May and June
