Rifle Gap Dam is about 5 1/2 miles north of Rifle, at a point where Rifle Creek cuts through the Grand Hogback.

The dam was built between 1964 and 1967 by the United States Bureau of Reclamation for irrigation water storage. The dam is operated by the Silt Water Conservancy District and creates Rifle Gap Reservoir. The dam area was also the site of the 1972 art installation “Valley Curtain” by Christo and Jeanne-Claude.
