Davis Dam is located on the Colorado River about downstream from Hoover Dam. Davis Dam stretches across the border between Arizona and Nevada and impounds the Colorado River to form Lake Mohave. The United States Bureau of Reclamation owns and operates the dam, which was completed in 1951. Davis Dam is a zoned earth fill dam with a concrete spillway, in length at the crest, and high. The earth fill dam begins on the Nevada side, but it does not extend to the Arizona side. Instead, there is an inlet formed by earth and concrete. At the end of the inlet is the spillway. The power plant is on the Arizona side of the inlet, perpendicular to the dam. This is a very unusual design. The hydroelectric plant generates between 1 and 2 terawatt-hours of electricity annually. The plant has a capacity of , and the tops of its five Francis turbines are visible from outside the plant. The plant's hydraulic head is . The dam's purpose is to generate hydroelectricity and regulate water releases into the Colorado River for use downstream by California, Arizona and Mexico.
