The Boise River is a 102-mile-long (164 km)^[2] tributary of the Snake River in the Northwestern United States. It drains a rugged portion of the Sawtooth Range in southwestern Idaho northeast of Boise, as well as part of the western Snake River Plain. The watershed encompasses approximately 4,100 square miles (11,000 km²) of highly diverse habitats, including alpine canyons, forest, rangeland, agricultural lands, and urban areas.
