Background
• Habitat surveys
• Restoration Projects• Riparian fencing/planting• Culvert replacements• Channel reconstruction• Road decommissioning• Nutrient enhancement• Water right transfers

Background
• Monitoring and Evaluation• Spawning escapement• Invertebrate – nutrient enhancement• Limited due to small sample sizes
• Genetic Assessments• Some “pure” populations
• New leadership• Status and trend monitoring• Project No. 2008-109-00

Goal and Objective
• Goal – restore healthy and harvestable salmonid populations
• Objective – rehabilitate stream habitat and restore ecological function in the riparian corridors

Management Questions
1. What are current habitat conditions?
2. Where are natural barriers?
3. Root causes of habitat degradation?
4. Highest priority restoration actions?
5. Current distribution and density of fish?5

Inventory and Assessment
• Habitat• Water Quality• Discharge• Invertebrate drift• Fish presence, relative density, and species
composition
• Level II – environmental attributes – EDT7
![Page 8: Lake Roosevelt Rainbow Trout Habitat/Passage Improvement Project No. 1990-018-00](https://reader035.fdocuments.in/reader035/viewer/2022062814/56816727550346895ddbbe4c/html5/thumbnails/8.jpg)
Study Design – Habitat Conditions
• Current Conditions – census• Habitat Inventory – ODFW protocol• Natural barriers – WDFW protocol
• Degradations – census• Culverts – National Inventory and Assessment
Procedure• Diversions, pumps, dikes, levees, rip rap, riparian
clearing – WDFW protocol

Study Design – Other Components
• CHaMP
• 50 sites – two strata• Sanpoil (n=25); E. side streams (n=25)• 12 fixed, 13 rotating panel (3 yr)
• Balanced across 6 multi-density categories• Land ownership (private, public)• Valley segment (source, transport, response)

Habitat Protection and Restoration Plan
10
• Process-based principles (Beechie et al. 2010)• Sequence of actions (Roni et al. 2008)
• Empirical observation• EDT Model results
![Page 11: Lake Roosevelt Rainbow Trout Habitat/Passage Improvement Project No. 1990-018-00](https://reader035.fdocuments.in/reader035/viewer/2022062814/56816727550346895ddbbe4c/html5/thumbnails/11.jpg)
Restoration Projects
• Riparian vegetation and streambank conditions
• Fish passage
• Channel migration potential & floodplain and sidechannel connectivity
• Instream flow & prevent entrainment or impingement of fish in irrigation structures

Example Prioritization Criteria - Barriers
• Biological• Quantity and quality of habitat upstream• Extent of passage in current condition• Number of focal species affected• Other benefits• Risk of catastrophic failure
• Feasibility• Land ownership• Size of road• Cost 13
