At the Council’s July 10, 2009 request, the ISRP reviewed the Colville Confederated Tribes’ Resident Fish Research, Monitoring, and Evaluation proposal (#2008-109-00), which is a Columbia River Fish Accords project.
The goal of this project is to improve the basic understanding of the population dynamics of rainbow trout (Oncorhynchus mykiss) within the San Poil Subbasin by examining movements and winter ecology among life histories. Specific project objectives include identification of spatiotemporal patterns in movements and spawning areas among life histories within the San Poil Subbasin; identification of overwintering areas of rainbow trout; and the investigation of how winter ecology of each present life history is associated with warm groundwater presence, river ice, and other habitat parameters to assist in determining where essential thermal refugia habitat exists to aid the Tribes in management decisions on where conservation and enhancement actions will provide the greatest benefit to the fish.
