The goal of this project is to provide temporary upstream passage for bull trout at Albeni Falls Dam, Pend Oreille River.  We propose to collect bull trout below the dam using boat electrofishing. The fish will then be transported above Albeni Falls Dam and released near Priest River, Idaho, or re-released below the dam depending on water temperature and number of fish captured.  Prior to release each fish will be implanted with a combination radio-acoustic transmitter to track the fish to potential spawning tributaries of Pend Oreille Lake. A system of stationary radio receiving stations and airplane/truck/boat surveys will be used to monitor the movement of the tagged fish. This project provides direct on-the-ground benefits for endangered bull trout in the Pend Oreille Basin because it will allow fish, whose migration corridor has been blocked by a dam without fish passage, to return to their natal streams and contribute their genes (which would otherwise have been lost) to the spawning population.
