The Boise River Diversion Dam is a diversion dam in the western United States, on the Boise River in southwestern Idaho. Seven miles (11 km) southeast and upstream of Boise in Ada County, it was completed 116 years ago in 1909 and is operated by the U.S. Bureau of Reclamation.
The diverted water fills the concrete New York Canal, the primary irrigation channel for Ada and Canyon counties in the Treasure Valley.
Several miles upstream of the Diversion Dam is Lucky Peak Dam. Completed in 1955, it was built and is operated by the U.S. Army Corps of Engineers.
