Monitoring and evaluation of the Colville Tribes' Resident Fish Hatchery (CRFH) provides feedback that guides future stocking and management strategies as part of an adaptive management process. The hatchery was created because federal hydropower projects, as well as private power utility systems, had and continue to have devastating impacts on anadromous and resident fish resources that once flourished in the Columbia River and its tributaries. Historical fish migrations were blocked by dams and their habitat was altered, negatively impacting a primary food resource (i.e., fish) for many native peoples. To replace these lost resources, many native peoples now rely heavily upon stocked hatchery fish. Artificial production at CRFH seeks to provide some mitigation for the loss of fish resources in the Upper Columbia Sub-Region within the "blocked area" created by the construction of Chief Joseph and Grand Coulee dams through hatchery supplementation and harvest augmentation (i.e., in-place, out-of-kind mitigation). This artificial production program is part of the Northwest Power and Conservation Councils resident fish substitution policy identified in their Fish and Wildlife Program. Specifically, the project monitors and evaluates resident fisheries and CRFH stocking strategies within the Colville Confederated Tribes' Reservation portion of the Upper Columbia, Sanpoil, and Okanogan Sub-Basins.

Primary objectives for the 2017–2018 performance period include:

1. Monitoring and evaluating stocking strategies implemented on all Reservation lakes and streams. Evaluation is based on specific metrics defined for each waterbody.
2. Monitoring water quality/habitat in stocked lakes.
3. Perform Lahontan Cutthroat Trout diet assessment.
4. Monitoring stocked Rainbow Trout movement in the Nespelem River to identify emigration rates into Rufus Woods Lake.
5. Monitor nutrient and water quality conditions in Omak Lake.
6. Complete final report on Buffalo Lake kokanee and Rainbow Trout carrying capacity.
7. Complete final report on Owhi Lake Brook Trout carrying capacity.
