Critical Data Gaps

Determine the relationship of egg-to-fry survival to flows after spawning. How does the timing and magnitude of flow reduction affect egg survival?
Observation or tracking of juvenile behavior to change in flow at time of Flip Flop. Do they shift habitats? What proportion migrate?
Determine the relationship of parr habitat capacity to flow
Estimate freshwater survival for each subbasin with substantial spring Chinook production
