Шаблон:Infobox dam Abiquiu Dam is a dam on the Rio Chama, located about Шаблон:Convert northwest of Santa Fe in Rio Arriba County, New Mexico, USA. Built and operated by the U.S. Army Corps of Engineers (USACE), the dam is an earth embankment structure Шаблон:Convert high and Шаблон:Convert long, containing 11.8 million cubic yards (9,022,000 m³) of fill. The dam forms Abiquiu Lake, one of the largest lakes in New Mexico, with a full storage capacity of Шаблон:Convert and Шаблон:Convert of water. To date, the reservoir has never filled to capacity, with a record high of Шаблон:Convert, 29.4% of full pool, on June 22, 1987. The dam's primary purpose is flood control, in addition to irrigation and municipal water storage, and hydroelectric generation.

History

The first proposal for a flood control dam on the Rio Chama was introduced in the Flood Control Act of 1948. The original plans called for the construction of a low dam at Chamita, about Шаблон:Convert downstream of the present site of Abiquiu Dam. In the 1950s a dam at Abiquiu was added to the project, and it was later determined that a single high dam at this site would be sufficient. In the subsequent Flood Control Act of 1960, the Chamita dam was removed from the project. Construction of Abiquiu Dam began in 1956 and the river was diverted in July 1959. Limited flood control operations began in 1962 and the dam was completed on February 5, 1963, at a cost of $21.2 million.

Upgrades

The dam initially functioned as a dry dam, with a very small permanent reservoir pool for sediment trapping purposes. In 1974 the city of Albuquerque petitioned the USACE for the regular storage of up to Шаблон:Convert in the reservoir as part of the San Juan–Chama Project. The USACE agreed in 1976 to allow this storage, also increasing the minimum reservoir volume to Шаблон:Convert for recreation purposes. In 1986, the dam was raised by Шаблон:Convert and the emergency spillway widened from Шаблон:Convert to Шаблон:Convert.

Hydroelectric plant

In 1990 a small power station was constructed at the dam base providing a capacity of 13.5 megawatts (MW). Between 2009 and 2011, the addition of a turbine increased the plant's capacity to 16.5 MW. The hydroelectric plant is operated by Los Alamos County Department of Public Utilities.
