Ruth Dam is located in northern California and was completed in 1958. The dam was built by the United States Bureau of Reclamation to provide irrigation water to the Central Valley Project. The dam is an earthfill structure with a height of 117 feet and a length of 540 feet. The reservoir created by the dam has a capacity of 50,500 acre-feet of water. The hydrology of the Ruth Dam is influenced by the nearby Sacramento River and the surrounding mountains. The dam is a significant provider of surface flow and snowpack for the area, which supports agricultural and recreational activities. The water from the reservoir is used for irrigation of crops such as almonds, walnuts, and rice. Additionally, the reservoir provides opportunities for boating, fishing, and camping.
