Grande Ronde \ Lostine Projects

Located in Northeast Oregon, the Lostine River Spring Chinook Supplementation Project serves to restore the ESA listed Lostine stock Chinook population in the Grande Ronde subbasin. Working cooperatively with Oregon Fish & Wildlife (ODFW), Confederated Tribes of the Umatilla Reservation (CTUIR), and the U.S. Fish & Wildlife Service (USFWS) the tribe leads the effort to recover this group of fish that was previously on the brink of complete extirpation in the late 1990’s.

Near the town of Lostine Oregon, the project operates a hydraulic weir that was constructed in 2010 to trap returning adult Chinook and Steelhead. The purpose of the weir is to provide management of the adult Lostine River populations including monitoring composition of adults passed above the weir for natural spawning, providing statistical information on the populations, and in the case of the Chinook Salmon provide broodstock. The retained Chinook broodstock are transported to Lookingglass Fish Hatchery where spawning, incubation and rearing occur. Once the juvenile rearing cycle has concluded, the fish are transferred to the tribe’s raceways on the upper Lostine River for several weeks of acclimation and release into their natal waters. Currently, the program’s production goal is to release a total of 250,000 Chinook Salmon smolts yearly in March and April.  The program has restoration goals for returning adult Lostine River Chinook Salmon that include achieving annual escapement of 500 natural adults, production of 1,625 annual returns of hatchery adults and provide harvest opportunities. These program adult goals have been met or exceeded since 2009.
