1. Assessing impact of restoration on salmonid population dynamics in the Entiat with life-cycle models James Murphy, Keith Van Den Broek, Tom Degroseillier TerraquaInc / ISEMP / CHaMP / USFWS

2. ISEMP life-cycle models: Integrating restoration and population dynamics • ISEMP life-cycle models for chinook and steelhead Life-cycle models that utilize ISEMP and CHaMP data. Focus on tributary spawning/rearing dynamics. In development for John Day, Lemhi, Salmon, Entiat. freshwater survival restoration population dynamics freshwater carrying capacity

3. Ongoing work for ISEMP and Entiat models Developing fish – habitat relationships Regression models with CHaMP data (field sampling, DEMs) NREI modeling Incremental flow methodology analyses Habitat-survival functional relationships Survival estimation Movement analyses Consideration of summer chinook dynamics / multi-species models

4. Entiat Spring Chinook Life Cycle Model valley segment 3 - Spatial structure - Pool volume per CHaMP site: 2013 valley segment 2 Mad River 1 2 3 upstream valley segments valley segment 1

5. Entiat Spring Chinook Life Cycle Model PIT tag marking 6 interrogators + RST Survival estimation Movement and emigration - Overwinter survival - Parr overwinter survival by area

6. Entiat Spring Chinook Life Cycle Model Time spent in valley segment 1 for fish tagged in upper Entiat: 2011-2013 - Parr movement - counts Number of days median = 2 days

7. Entiat Spring Chinook Life Cycle Model Emigration timing by summer parr location: detections at screw trap and ENL array at mouth - Emigration - valley segment 3 valley segment 2 counts valley segment 1 yearling subyearling Julian day
