Resident Fish Planning: Dworshak Reservoir, Lake Roosevelt and Lake Pend Oreille.
Research projects are presently being conducted to reduce the amount of uncertainty in how reservoir operations within the Columbia River federal power system affect resident fish. Many of these research projects are being conducted to better define operation strategies being proposed under the Columbia River System Operation Review (SOR). This project provides a basis for understanding the potential effects of different operating strategies being considered under the SOR in reservoir fisheries at Lake Roosevelt, Dworshak Reservoir, and Lake Pend Oreille. The methodological framework used here was adapted from the Regional Assessment of Supplementation Project (RASP), a project framework used for evaluating supplementation strategies for anadromous fish. RASP attempts to diagnose the factors that limit production of fishes and outlines a process that can be followed to systematically reduce uncertainty while achieving the objective. In all three reservoirs concerns exist about protecting sensitive species, particularly bull trout and cutthroat trout. In all three reservoirs a need exists for additional baseline information to provide an adequate understanding of the populations of interest.
