The Salmon River is the largest undammed river in the lower 48 states. It flows freely from the deep wilderness of Idaho for 425 miles until it meets the Snake River. The Salmon River balloons in the spring with all the melting snow runoff from the Sawtooth Mountains, Salmon River Mountains, Lemhi Range, Clearwater and Bitterroot Ranges. The Lower Salmon River is best run for whitewater rafting after the spring runoff during July and August.
