TheGrand Valley Diversion Dam is adiversion dam in theDe Beque Canyon of theColorado River, about 15 miles (24 km) northeast ofGrand Junction,Colorado in theUnited States. It is a 14-foot (4.3 m) high, 546-foot (166 m) long concreteroller dam with six gates, which were the first and largest of their kind to be installed in the United States.[3]
The dam was built between 1913 and 1916 as part of the Grand Valley Project of theU.S. Bureau of Reclamation (USBR) and diverts water into theGovernment Highline Canal for the full irrigation of 33,368 acres (13,504 ha) and supplemental irrigation to 8,600 acres (3,500 ha) in western Colorado'sGrand Valley.[1] A smallhydroelectric plant with a capacity of 3,000kilowatts (KW) was completed in 1933 on the Orchard Mesa Power Canal, a branch of the Government Highline Canal.[1] In 1949, the dam and canal system were transferred to the Grand Valley Water Users Association, while the power plant was consigned to the Orchard Mesa Irrigation District.[1]
Grand Valley Diversion Dam was listed on theNational Register of Historic Places on October 8, 1991.[4]
