Angostura Diversion Dam

The Angostura Diversion Dam is a diversion dam on the Rio Grande in Sandoval County. New Mexico, near to Algodones and to the north of Bernalillo. The dam diverts water into the main irrigation canal serving the Albuquerque Division.

The Angostura Diversion Dam consists of a concrete weir section 17 ft high and 800 ft long. The dam was built in 1934 by the Middle Rio Grande Conservancy District (MRGCD), and in 1958 was rehabilitated by the United States Bureau of Reclamation and the Corps of Engineers as part of the Middle Rio Grande Project. It has a diversion capacity of 650 ft3 per second. Four 20 by top-seal radial gates supply water to the Albuquerque Main Canal. The MRGCD is responsible for operations and maintenance.
