  1. Middle Fork ProjectOverview of 2008 Technical Study Plan Implementation April 21, 2008

  2. AQ 1 – Instream Flow • 2008 Field Surveys Instream • 12 Fish Study Sites (high, medium, and low flows) • Rubicon River High Flow Issue • 4 Sites with 2D for FYLF • 5 Riparian Study Sites (high, medium, and low flows) • 2 FYLF Stage Locations (NF near Shirttail, NFMF) • 2D Model Validation • FYLF Egg Masses and Tadpoles • Coordinate with Geomorphology, Riparian, Amphibian and Aquatic Reptile, and Recreation TSPs • Stranding Evaluation • Snorkel 3 Large Pools/Write-up • Peaking Reach Stage Monitoring • Document Algae Abundance and Presence of Didymo • Quantify Flow Level For Horseshoe Bar Channel

  3. AQ 1 – Instream Flow (cont.) • Habitat Modeling • Develop HSC • Coordinate with Riparian, Geomorphology, and Special-status Amphibian and Aquatic Reptile TSPs • Document Results in 2009 Instream Flow TSR

  4. AQ 2 – Fish Population • Draft Report Comments • Ralston Afterbay Sampling • 2 Times (early summer and fall) • Gillnets, Boat Electroshocking, Sonar, Water Temp • Determine 2008 Sampling Sites with Aquatic TWG • River Study Sites • Qualitative Hardhead Distribution • Identify Appropriate River Fish Standing Crop Comparison Data Sets • Document 2008 Results in 2009 Fish Population TSR • Misc. • Duncan Diversion Pool • Fish Scales (coordinate with fishermen?) • Periodicity Chart

  5. AQ 3 – Macroinvertebrate andSpecial-status Mollusks • Draft Report (Coming Soon) • Mollusk Field Study (20 sites) • See map (4 sites with WPS mussels) • Consult with TWG Regarding Water Quality Results & Potential BMI Sampling • Document 2008 Mollusk Results in Macroinvertebrate and Special-status Mollusks TSR • Present Drift Sampling Results in the 2009 Bioenergetics Study Report

  6. AQ 4 – Water Temperature Modeling • Water Temperature and MET Data Collection (2007-2008) • Tunnel Sites • Data Collection • Temperature Refugia (Tributaries/Pools) • Travel Times • Develop Temperature Model • Water Temperature Modeling Subgroup • Select Models • Develop and Calibrate Models • Analyze Data and Develop Water Temperature Analysis • Scenarios • Betterments • Global Warming • Empirical Analysis of Small Streams • Document Results in 2009 Water Temperature Modeling TSR

  7. AQ 6 – Fish Passage • Draft Report (Coming Soon) • Consult with Aquatic TWG to: • Determine if Hydrodynamic Modeling is Required at any Barriers • Discuss Passage at Project Facilities • Document 2008 Surveys in 2009 Fish Passage TSR

  8. AQ 7 – Entrainment • White Paper Analysis Report (Coming Soon) • Consult with TWG to: • Determine Entrainment Mitigation • Determine Need for Entrainment Sampling • If Necessary, Conduct 2008-2009 Entrainment Sampling • Document sampling in 2010 Entrainment TSR

  9. AQ 9 – Geomorphology • Characterize Sediment Capture in Reservoirs • Survey French Meadows and Hell Hole reservoirs, Ralston Afterbay, Duncan Diversion, and Middle Fork Interbay • Betterment • Shoreline Erosion with Hell Hole Storage Increase • Hydrology • Flood Frequency Analysis • Sediment Transport Calculations • High Flow Measurements if Possible • Bankfull Identification • Consult with Aquatic TWG on Need for Empirical Sediment Transport Data Collection • Document 2007 and 2008 Results in 2009 Geomorphology TSR

  10. AQ 10 – Riparian Resources • Conduct 2008 Field Surveys • Project Betterments Riparian Vegetation (Hell Hole Reservoir and Five Lakes Creek) • Tree Cores from the Rubicon River Downstream from Hell Hole Dam (R25.7) • Instream Flow Measurements (in Coordination with AQ 1) on Comparison Streams and Bypass Streams (if possible) • Riparian Mapping at Peaking Reach 2D Modeling Sites • Document 2007 Comparison Stream and 2008 Analysis Results in 2009 Riparian Resources TSR

  11. AQ 11 – Water Quality • Draft Report Comments • Consult with TWG to Determine if: • Results from the 2007 Water Quality Sampling Program Indicated Potentially Adverse Water Quality Conditions that Require Additional Sampling (Water Quality and/or BMI) • Additional Fish Tissue Mercury Sampling is Necessary • If Necessary, Complete 2008 Sampling • Document 2008 Results in 2009 Water Quality TSR

  12. AQ 12 – Special-status Amphibian and Aquatic Reptiles Draft Report Comments FYLF • Stage Data at NF35.7 and NFMF1.6 (1-3 cross-sections) • Collect Modeling Validation Data at 2D Sites • Egg Masses/Tadpoles • Breeding Timing (Initiation of Breeding) • Additional Breeding Timing Data (Shirttail, Otter Creek) • Consult with TWG to Identify any Data Gaps: • Identify if Additional Limited-scope 2008 Surveys are Needed (e.g., breeding and timing, site revisits) CRLF • Complete CRLF Surveys in 2009 (Horseshoe Bar & Ralston Ridge) • Document 2008 Survey Results in 2009 Amphibian TSR
