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 a combination of a floating trap that can be positioned at a variety of locations in the tailrace and boat electrofishing. Experiments will be conducted to determine if attraction of bull trout into the trap can be improved by adding bull trout pheromones, water from a bull trout home stream or cold water to the attraction flow from the trap. Trap efficacy will be determined by comparing the number of bull trout caught in the trap to the number caught by electrofishing. Any bull trout captured will be biopsied via hole punch and their DNA sent to the USFWS lab in Abernathy, Washington for rapid analysis within 48 hours. Each DNA sample will be compared to DNA from other bull trout populations in the Priest River drainage, Pend Oreille lake tributaries, and Clark Fork drainage and an assignment will be made as to its probable tributary of origin. The fish will then be transported above Albeni Falls Dam, Cabinet Gorge Dam or other dams without fish ladders, so that they will be able to volitionally migrate into their assigned home tributary, drop back downstream, or migrate upstream to the next dam. Prior to release each fish will be implanted with a combination radio-acoustic transmitter to ascertain if the spawning tributary it selected was the same as its assigned tributary. 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.
