Lostine spring chinook are an ESA listed population in the Wallowa/ Grande Ronde subbasin. The tribe as lead in cooperation with the Oregon Department of Fish & Wildlife (ODFW), Confederated Tribes of the Umatilla Indian Reservation (CTUIR), and the United States Fish & Wildlife Service (USFWS), supplement the juvenile population with 250,000 smolts released annually. Extremely low smolt numbers have necessitated a combined "conventional" and "captive broodstock" effort to increase juvenile smolt numbers and increase adult returns. We hope to see adult returns consistently greater than 1,500 annually.
In 2006, construction of a new Lostine Hatchery will begin. By 2008, the Lostine Hatchery will begin producing both Lostine (250,000) and Imnaha (248,000) spring chinook smolts.
In
March 2005, a total of 164,819 spring chinook salmon smolts (66% of goal)
were released into the Lostine River from the acclimation facility. In May 2005,
the Lostine River weir began trapping returning adult salmon. The run
is expected to have upwards of 750 adults reach the weir. Approximately, 75-80 females are needed annually to privide 250,000 smolts.
