Resident Fish Above Chief Joseph and Grand Coulee Dams Project No. 1997-004-00 Kalispel Tribe of Indians Washington Department of Fish and Wildlife Spokane Tribe of Indians Colville Confederated Tribes Jason Connor Charles Lee January 18, 2012
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.
Box Canyon Reservoir northern pike and resident fish monitoring Gill netting Survey Abundance Growth, size and age structure Condition Maturity, fecundity Diet Total annual mortality Gill net, fyke net, electrofishing Species composition Relative abundance Growth, size and age structure Condition WDFW Standardized warmwater surveys (3-5 yrs.) Spring Pike Index Netting Surveys SPIN (annually)
Priest Lake and Upper Priest Lake lake trout stock assessment 1.Movement, behavior, and survival 2.Abundance 3.Population structure IDFG methods developed at Lake Pend Oreille Trap nets, gill nets Acoustic telemetry

Native Redband Trout Stock Assessment in Lake Roosevelt and the Upper Columbia River Genetic Composition Recruitment Harvest Escapement Interactions with hatchery stocks Provide stock assessment data to managers to help in developing strategies to manage for recreational and subsistence harvest, while promoting healthy wild populations.
