The Cochiti Dam is a dam on the Rio Grande in Sandoval County (New Mexico) about 80 km north of Albuquerque , New Mexico in the USA. With a construction volume of 48,052,000 m³ (other source: 50.23 million m³) it is one of the largest dams in the world and one of the largest 10 in the USA. The Cochiti Dam is one of four structures of the United States Army Corps of Engineers for flood and sediment control in the river basin of the Rio Grande, together with the Abiquiu Lake , Galisteo and Jemez Canyon dams .
use
The Cochiti Dam is primarily a flood control facility designed to mitigate the effects of heavy rainfall. The dam and the reservoir have recreational facilities as secondary use and serve ecology. The extraction devices can drain 418.8 m³ / s.
The dam is operated in such a way that the discharge is regulated to the extent that the underwater can safely handle. The flood control comes into effect when the inflow is higher than the capacity of the underflow. The stored flood is drained when the lower reaches allows, in accordance with Public Law 86-645 and the Rio Grande Compact .
Building history
The Cochiti Dam was approved by a 1960 law for construction costs of US $ 94.4 million.
Construction began in 1965, the dam was finished in 1975, but the damming of the lake began in 1973. Before that, there were archaeological studies.
The rising water level flooded the Cochiti distribution dam, which had previously been built for irrigation.
The construction of the dam was fought by the Cochiti- Pueblo Indians, who lost significant arable land. They tried and won the Army Corps of Engineers. In 2001 the Army Corps of Engineers apologized publicly to the Indians.
The reservoir "Cochiti Lake"
Since its completion, the Cochiti reservoir has had a permanent traffic jam for recreational recreation of around 62 million m³. In addition, there is a changing traffic jam in the branch of the Santa Fe River. Around 1.2 million m³ of sediments are deposited every year.
There are two public recreational areas on the reservoir, one on the west side (Cochiti Recreation Area) and one on the east side (Tetilla Peak Recreation Area). Other areas around the lake are part of the Cochiti Indian Reservation and are not open to the public. There is a visitor center.
