The Lake Pend Oreille/Dworshak Resident Fish Mitigation Project is partial mitigation for impacts to resident fish populations and resulting fisheries from of Albeni Falls and Dworshak Dams. These projects primarily focus on status and trend monitoring in order to inform conservation actions carried out by Idaho Department of Fish and Game. In Lake Pend Oreille, predator (primarily Lake Trout and Walleye) suppression to prevent food web collapse continues to be the primary management tool for sustaining the fish assemblage, including native Bull Trout and Westslope Cutthroat Trout. This project contributes to the predator suppression program, with a substantial cost-share from Avista Corporation. The project has demonstrated remarkable success to date, with continued collapse of the Lake Trout population and a concurrent recovery of the kokanee population. However, the potential for predatory inertia to collapse the fishery remains a real risk because of the diversity of apex predators in the system. Therefore, this project continues to be science-based and primarily focused on adaptive predator management and robust monitoring of key fish populations.  To inform adaptive management of predator suppression programs, we will collect critical monitoring data for kokanee, Bull Trout, Lake Trout, Walleye, Northern Pike, Rainbow Trout, and Mysis diluviana. Analyses of these results will be used to improve suppression efficiency and monitor responses from targets of suppression, as well as the components of the fishery we are working to conserve. In Dworshak Reservoir, we will continue monitoring programs to manage the nutrient restoration project in conjunction with the U.S. Army Corps of Engineers. This project has demonstrated continued success in its ability to reduce harmful algal blooms and generally improve the overall productivity of the Dworshak Reservoir food web, including the kokanee population. This project will continue monitoring to assess the status and trend of the limnology, kokanee, and other fishery components of Dworshak Reservoir. The mitigation programs on Lake Pend Oreille and Dworshak Reservoir covered by this project will continue to be critical components of management of these regionally important fisheries. Additionally, the work conducted by this program serve as important case studies to similar management and mitigation programs throughout the Columbia Basin.
