3. Walla Walla Subbasin Summary and Draft Subbasin Plan Limiting Factors Physical Fish Passage Impediments: Adult impacts at diversion structures Juvenile impacts at irrigation canal screens Fish Species Impacted: Summer Steelhead (ESA) Bull Trout (ESA) Spring Chinook Physical Fish Passage Impediments: Adult impacts at diversion structures Juvenile impacts at irrigation canal screens Fish Species Impacted: Summer Steelhead (ESA) Bull Trout (ESA) Spring Chinook

4. Walla Walla Subbasin Summary Goals Goals Enhance steelhead & bulltrout (BT) Reestablish spring chinook (CHS) Provide sustainable fisheries Goals Enhance steelhead & bulltrout (BT) Reestablish spring chinook (CHS) Provide sustainable fisheries Objectives Return 5,650 adult steelhead Return 5,500 adult CHS Self-sustaining BT & Lamprey Objectives Return 5,650 adult steelhead Return 5,500 adult CHS Self-sustaining BT & Lamprey

5. Project Objective Provide passage at irrigation diversion structures for migrating juvenile and adult salmonids in the Walla Walla Basin Final planning and design Construction Passage facilities O&M Passage facilities M&E Provide passage at irrigation diversion structures for migrating juvenile and adult salmonids in the Walla Walla Basin Final planning and design Construction Passage facilities O&M Passage facilities M&E

6. Project Consistent With Subbasin Summary Strategies Restore and enhance fish passage for upstream and downstream migrants Continue inventory and prioritization Implement screening improvements Consolidate diversions where possible Implement adult passage improvements O&M of passage facilities M&E – respond with adjustments Restore and enhance fish passage for upstream and downstream migrants Continue inventory and prioritization Implement screening improvements Consolidate diversions where possible Implement adult passage improvements O&M of passage facilities M&E – respond with adjustments
