Anthropology

The Salmon River area has been home to people for at least the last 8,000 years. Much of the area was inhabited by several tribes, including the Nez Perce. The river was a rich source of food for the indigenous people of the area, who relied on the abundant salmon species and other wildlife.

 ventured down the Salmon River, but found it to be too rough to be navigable. Clark wrote:
"...I shall in justice to Capt. Lewis who was the first white man ever on this fork of the Columbia Call this Louis's river. ...The Westerly fork of the Columbia River [the present Salmon River] is double the size of the Easterley fork [the present Lemhi River] & below those forks the river is ...100 yards [100 m] wide, it is very rapid & Sholey water Clear but little timber."


The honor didn't last long; by 1810 maps of the area were already referring to "Louis' River" as the Salmon. Clark had thought that the Salmon River was the Snake River, thus he called it the "Westerly fork of the Columbia". The Snake River retained the variant name "Lewis River" or "Lewis Fork" longer than did the Salmon.

Salmon River Canyon 1945


U. S. Coast & Geodetic Survey
of Oscar Risvold

The Salmon River historically produced 45% percent of all the steelhead (salmon) and 45 percent of all the spring and summer chinook salmon in the entire Columbia River Basin. The Salmon River basin contains most (up to 70 percent) of the remaining salmon and steelhead habitat in the Columbia River Basin. Despite the abundant salmon habitat in the river, these fish have been declining, in large part because of the effects of four federal reservoirs and dams on the lower Snake and Columbia rivers.
