Project Goals
1.Assess current fishery and habitat conditions in the Blocked Area using regionally standardized data collection methods.
2.Compile standardized fishery, habitat, and water quality data into publically accessible database to facilitate data sharing, transparency, and ensure policy makers and managers have access to the latest research with which to base decisions.
3.Recommend and implement management actions based on research results.
Major Accomplishments
1.Baseline tributary and lake fishery and habitat assessments.
2.Box Canyon Reservoir resident fishery and northern pike invasion.
3.Redband trout stock assessments on Spokane River, Lake Roosevelt, and upper Columbia River.
4.Westslope cutthroat trout movement and survival in the Priest/Pend Oreille rivers.
5.Burbot stock assessments in Bead and Sullivan lakes.
Objectives
1.Native redband trout stock assessment in lower Spokane River, Lake Roosevelt, and upper Columbia River.
2.Lake trout stock assessment in Priest and Upper Priest lakes.
3.Box Canyon Reservoir northern pike and resident fish monitoring.
4.Data management.
