The Boise River is a tailwater fishery that begins in the Sawtooth Mountains where three forks - the North Fork, Middle Fork, and South Fork - converge before flowing approximately 102 miles to its confluence with the Snake River. Below Lucky Peak Dam is considered the lower Boise River, which flows about 65 miles through the city of Boise and surrounding areas, creating one of the finest urban trout fisheries in the country. This multi-use stream serves diverse user groups and offers exceptional fishing opportunities for a variety of species. The river's character changes along its course, with coldwater species dominating the upper sections and transitioning to warmwater species in the lower reaches. The tailwater sections below dams provide consistent water temperatures and conditions that support healthy populations of both wild and stocked trout.
