Snake River Basin steelhead are listed under the ESA and subject to harvest and hatchery programs. Spawning escapement throughout the basin is calculated from numerous data sets. We are conducting a sensitivity analysis on procedures used to calculate steelhead spawning escapement throughout the Snake River Basin. Our results will improve transparency, implementation, and accuracy of the methods used to generate management metrics. The project is imbedded within an existing collaboration between three state agencies and tribal comanagers.
