Streamflow Elevation Profile

The Salmon River is located in Idaho in the northwestern United States. The Salmon is also known as "The River of No Return". It flows for 425 miles (685 km) through central Idaho, draining a rugged, thinly populated watershed of 14,000 square miles (36,000 km2) and dropping more than 7,000 feet (2,100 m) between its headwaters, near Galena Summit above the Sawtooth Valley in the Sawtooth National Recreation Area, and 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). It is one of the largest rivers in the continental United States without a single dam on its mainstem.Cities located along the Salmon River include Stanley, Clayton, Challis, Salmon, Riggins, and White Bird. Redfish Lake and Little Redfish Lake near Stanley, which flow into the river via Redfish Lake Creek, are the terminus of the longest Pacific sockeye salmon migration in North America.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.
