The first dam was so deteriorated by 1975 that the reservoir was only holding two thirds of its capacity. The replacement dam was designed and constructed by Bechtel Corporation. It is currently operated by the Bureau of Reclamation and provides irrigation, flood control, power generation, recreation, and the improvement of fish and wildlife resources.
