Reclamation Information Sharing Environment (RISE)

Rifle Gap Dam, completed in 1967, is located on Rifle Creek in west-central Colorado. Rifle Creek, formed by the confluence of the East, Middle, and West Rifle Creeks immediately north of the Grand Hogback, cuts through the Hogback at Rifle Gap and flows into the Colorado River near the town of Rifle. The dam and reservoir are part of the Silt Project. Project water is stored in Rifle Gap Reservoir, and exchange releases are made from Rifle Creek to existing ditches to meet downstream irrigation needs.
