The Salmon River, also known as the "River of No Return", is a river located in the U.S. state of Idaho in the western United States. It flows for 425 miles (685 km) through central Idaho, draining a rugged, thinly populated watershed of 14,000 square miles (36,000 km2). The river drops more than 7,000 feet (2,100 m) from its headwaters, near Galena Summit above the Sawtooth Valley in the Sawtooth National Recreation Area, to its confluence with the Snake River. Measured at White Bird, its average discharge is 11,060 cubic feet per second (82,700 US gal/s; 313 m3/s).[5] The Salmon River is the longest undammed river in the contiguous United States.[6]
Settlements located along the Salmon River include Stanley, Clayton, Challis, Salmon, Riggins, and White Bird. Redfish Lake and Little Redfish Lake, which flow into the river via Redfish Lake Creek, are the termini of the longest Pacific sockeye salmon migration in North America.[7] The lower half of the river provides the time zone boundary for the state, with northern Idaho on Pacific Time and the rest of the state on Mountain Time.
