The Middle Rio Grande Project was authorized by the Congress to improve and stabilize the economy of the Middle Rio Grande Valley by rehabilitation of the Middle Rio Grande Conservancy District facilities and by controlling sedimentation and flooding in the Rio Grande. The Bureau of Reclamation and the Corps of Engineers jointly planned the comprehensive development of the project. Reclamation undertook the rehabilitation of El Vado Dam, rehabilitation of project irrigation and drainage works, and channel maintenance. The Corps of Engineers was assigned the construction of flood control reservoirs and levees for flood protection.

There are three diversion dams, all of which have been rehabilitated. Angostura Diversion Dam, serving the Albuquerque Division, consists of a concrete weir section 17 feet high and 800 feet long; Isleta Diversion Dam, serving the Belen Division, is a reinforced concrete structure 21 feet high and 674 feet long with 30 radial gates; and San Acacia Diversion Dam, serving the Socorro Division, is 17 feet high and 700 feet long with 29 radial gates. Lands in the Cochiti Division, previously served by the Cochiti Diversion Dam, now receive their supply directly from Cochiti Dam, a Corps of Engineers flood control dam. Cochiti Diversion Dam was inundated by the construction of Cochiti Dam.
