6 Juvenile Life History and Maternal Run Timing of Chehalis River Spring and Fall Chinook Salmon 1. Evaluate the successful juvenile life histories of naturally reproducing fall and spring Chinook salmon (Fry/Parr/Yearlings) 2. Linkage between life history expression, habitat proximity, and environmental conditions 3. Provide an independent estimate of maternal run timing (spring or fall) for individuals that were classified as spring or fall in the field
