The agreement with the Umatilla, Warm Springs, and Yakama tribes and the Bonneville Power Administration, U.S. Army Corps of Engineers, and Bureau of Reclamation focuses on improving fish passage at federal dams, restoring habitat, and using hatcheries to rebuild anadromous fish populations. The agreement extends through September 2018. See Accords and Accords Partners.
Columbia River Fish Management Plan (CRFMP) A consent decree approved by and entered as an order of the district court in U.S. v. Oregon, in which the parties to U.S. v. Oregon may exercise their sovereign power in a coordinated and systematic manner to protect and rebuild upper Columbia River fish runs and allocate their harvest between Indian and non-Indian fisheries.
Columbia River Inter-Tribal Fish Commission (CRITFC) A coordinating fisheries agency, founded in 1977 by the Nez Perce, Umatilla, Warm Springs, and Yakama tribes—the four Columbia River tribes that reserved fishing rights in 1855 treaties with the United States government. CRITFC, through its staff of biologists, policy analysts, law enforcement officers, and other specialists, strives to protect the tribes’ fishing rights and works to restore the fish resources upon which tribal religion, culture and livelihood depend.

U.S. v. Oregon The federal court case that upheld the treaty fishing rights of the Columbia River treaty tribes in a 1969 decision. The case remains under the court’s jurisdiction. Federal District Judge Robert Belloni recognized the rights of tribes to fish at all usual and accustomed fishing places and rules that the tribes are entitled to a “fair share” of the fish runs. The decision holds that the state is prohibited from discriminating against treaty fishing and that state power is limited in regulating treaty Indian fisheries, i.e., the state can regulate only when “reasonable and necessary for conservation.”
U.S. v. Washington A 1974 federal court case that reaffirmed Puget SoundWestern Washington tribes’ reserved rights to 50% of harvestable salmon. Subsequent proceedings ruled that the treaty right included the right to harvest hatchery fish and imposed a duty on the state to protect salmon habitat. The Yakama Nation is a party in the case, which like U.S. v. Oregon continues under the jurisdiction of the federal district court.
United States-Canada Pacific Salmon Interception Treaty (also called the Pacific Salmon Treaty or PST) Signed in 1985, the United States-Canada Pacific Salmon Treaty limits each country’s interception of the other’s salmon to promote the ability of stocks to rebuild in both nations. The two countries’ governments made new treaty agreements in 1999 and most recently in 2008.
upstream migration The return of adult salmon from the ocean to inriver areas where they were born and where they will spawn the next generation.
