  1. Built 1946-56 New license studies & application 1991-95 Watershed analysis 1996-98 Settlement Agreement 2001 RCC forms to implement SA New License issued 2003 (Nov 13) New License FINAL 2005 (Oct 18) 35 year term

  2. Resource Coordination Committee • Monthly meetings / calls • Annual Reports to FERC • BLM, NMFS, ODFW, ODEQ, OWRD, PacifiCorp, USFS, USFWS

  3. Flowpaths, flow regulation reservoir fluctuation reservoir

  4. SA 5 and 6: Flow and Ramping • Higher minimum flows in all bypass reaches • Reduced ramping (flow fluctuations caused by power generation) in all bypass reaches and Lemolo Lake

  5. PacifiCorp’s continuous-recording, compliance-related gages on the NUHP Gaging network for flow and ramping compliance

  6. SA 5.5 Flow and Ramping Monitoring Gage stations, continuous records, real-time public access to 10 streamgages

  7. SA 5 Flow Monitoring Plan 2004; 2007 SA 5 instream flow increases, 2005 Soda Springs 25  275 (11x) North Umpqua 25  50-80 (2-3x) Clearwater River 5  40-60 (8-12x) Fish Creek 10-20  50-80 (2-8x) SA 5 instream flow increases, 2006 Deer Creek 1  all flow Potter Creek 0  all flow White Mule Cr 0  all flow Plus 5 smaller diversions all removed

  8. Fish Creek forebay, October 14, 2007

  9. Flow increase and stability in rivers (Toketee bypass example)

  10. some ramping challenges persist

  11. SA 6+ Lemolo 2 tailrace Re-route 2007: more impact review, conceptual design2008: exploratory boring, design

  12. SA 6.9 Slide Cr PH emergency ramping evaluation • 2006: • Study plan • Field study • Historical analysis • Report (Hardin Davis) • 2007: • Complete consultation

  13. SA 4.3 Lemolo 2 fish ladder evaluation (post-modification) 2006: hydraulic 2007: biological

  14. SA 7.2 Gravel Augmentation Program • Gravel pulse experiment completed 2006-7 • Revise Implementation and Monitoring Plans

  15. SA 7.3 LWD passage at Slide and Soda Springs Log chute open Whole log staged

  16. SA 8.2 Slide Creek Bypass Reach Habitat Project Adaptive Design and Construction 2002-5 Monitoring: began in 2006 2007: report from TWG to RCC, FERC Repeat in 2011 for final report

  17. SA 8.3 Mainstem Spawning Habitat

  18. Habitat construction, 2004

  19. Soda Springs Spawning Habitat Project Annual Monitoring Periodic Maintenance Annual Reports created 15,000 sqft new spawning habitat for chinook salmon (enough for about 300 redds)

  20. SA 9 Lemolo Lake Management Plan Annual drawdown predictions and planning 2006-7: BGA advisories 2007: TWG formed to address BGA issues

  21. Lemolo Lake Sampling August 2007

  22. Terrestrial Resources • Aquatic Connectivity • Re-establishing diverted tributary creeks • Aquatic site reconnections across waterways • Wetland Enhancement • Enhancement/creation of 8 wetland sites • Stump Lake and Lemolo Lake completed • Terrestrial Connectivity • Big game bridges • Wildlife crossings • Penstock crossings

  23. Clearwater Reconnection Potter Creek

  24. Culvert replacements for fish passage Fish Creek Canal Road, Cedar Spring and Velvet Cr

  25. Stump Lake Wetland

  26. Terrestrial Connectivity • Big game bridges • 29 required • 29 complete • Wildlife crossings • 34 required • 9 complete in 2007 • All complete in 2008 • Penstock crossings • 9 required • 9 complete

  27. SA 19 Soda Springs Predator Study Pilot field work 2004-2006

  28. 2007 Major Predator Study April-June • Field work completed • Report in progress at • Stillwater Sciences

  29. Long-term monitoring of anadromous fish populations and passage success ~ 35-year program ~

  30. Smolt trapping (March - October) Spawner surveys (September - May)

  31. SA 4: Fish Passage Facilities(design, plan, build, evaluate) • Soda Springs tailrace barrier (2003-7) • Lemolo 2 ladder modifications (2004-7) • Clearwater Reconnect (2004-8) • Fish Creek screen (2006-9) • Soda Springs ladder/screen/spill (2007-12) • Slide Creek tailrace barrier (2009-11)

  32. New Facility Life Stages • Conceptual Design (1-2 years) • Objectives, footprint, location • Final Design, O+M and Evaluation Plans (1-2 years) • 30%, 60%, 90% reviews, final approval • Additional approvals / permitting (2-6 mo) • FERC approval • DSL / ACOE fill-removal permits, WQ certification • USFS Authorization • Construction plans / bids (2-6 mo) • How to build it? Modify permits? • Build – inspect and monitor construction • Evaluate, Improve, Complete • Transition into routine operation

  33. SA 4.1 Soda Springs Tailrace barrier concept

  34. Tailrace barrier construction June-October 2007

  35. Tailrace barrier nearing completion, coffer dam removal (October 2007)

  36. Completed Tailrace Barrier(Nov 2007)

  37. Transition into routine operation Operating hoist to clean leaves and debris from tailrace barrier pickets

  38. Fish Creek Diversion Dam Diversionof Fish Creek to settling basin Fish Creek Flow Fishladder

  39. SA 4.2 Fish Creek fish screen

  40. Fish Creek Screen 2007 Concrete structures and bypass pipe completed Finish as weather permits in 2008, evaluate in 2009
