REMARKS - Water years 2014-2019; records good except for estimates, which are poor. Reservoir is formed by earthfill dam, completed in 1926, capacity, 561 acre-ft. Raised 3 ft in 1935, capacity, 650 acre-ft, and raised 36.5 ft more in 1947, capacity, 2,615 acre-ft at gage height 96.6 ft, crest of concrete spillway. Between Oct. 1947 and May 1953, varying amounts of sandbag bulkheads were placed on crest of spillway to increase capacity. Between May 1953 and Dec. 1971, spillway was equipped with radial gates that opened automatically, thereby increasing capacity to more than 3,000 acre-ft. Radial gates were removed during 1972, capacity, 2,615 acre-ft. In 1995, modifications to the dam and spillway increased capacity to 3,257 acre-ft. Only the storage of Rio Grande water in excess of 1,061 acre-ft is subject to terms of the Rio Grande Compact. No dead storage.
