Boise River

The Boise River is a natural waterway that flows approximately 102 miles through southwestern Idaho, primarily through Boise and surrounding communities. Originating from glaciers in the Sawtooth Mountains, it provides a vital source of water for irrigation, recreation, and wildlife habitats. The river passes through urban and rural areas, supporting diverse ecosystems and offering activities such as fishing, boating, and birdwatching. Managed by various agencies, efforts are in place to maintain its health, manage flood risks, and preserve its scenic and ecological value for both residents and visitors.
