Province Summary


Blue Mountain

The Blue Mountain Province includes the Asotin Creek, Grande Ronde River, and Imnaha River subbasins, as well as the Snake River and small tributaries between the mouth of the Clearwater River at Lewiston, Idaho (river mile 138) and Hells Canyon Dam (river mile 247). These subbasins encompass 6,036 square miles, of which 79% are in Oregon, 12% in Washington, and 9% in Idaho. Chinook, summer steelhead, sockeye, and bull trout populations within the province are listed under the federal Endangered Species Act. Rugged peaks reaching 7,700 feet in the Blue Mountains and 10,000 feet in the Wallowa Mountains influence the character of the subbasins. Much of the higher elevation land is publicly owned, whereas privately owned land is generally at lower elevations along streams and on valley floors. Most of the Snake Hells Canyon Subbasin is publicly owned, and is protected or managed using conservation based strategies. The Blue Mountain Province is sparsely populated, with the economy largely dependent on agriculture, forestry, ranching, and mining.
