Lake Mohave is a reservoir on the Colorado River created in 1951 following the completion of Davis Dam near present-day Laughlin, Nevada, and Bullhead City, Arizona.
Named for the Mohave Indians who previously inhabited this region of the Colorado River valley, Lake Mohave extends approximately 67 miles along the valley from Hoover Dam to Davis Dam straddling the southern Nevada and northwestern Arizona border, which follows the original river channel.
Construction of Davis Dam was a requirement of the 1944 Water Treaty with Mexico to regulate water released from Hoover Dam for delivery to Mexico. Lake Mohave is used for that purpose through integrated operations with Hoover Dam. In 1947, the area where Lake Mohave would form and surrounding lands were added by revision to the Memorandum of Agreement between the National Park Service and the U.S. Bureau of Reclamation for the previously designated "Boulder Dam Recreation Area," which in 1964 would become Lake Mead National Recreation Area.
Lake Mohave provides a variety of recreational opportunities, including boating, fishing, and scuba diving. Three marinas with launch ramps are located on Lake Mohave, two in Arizona (Willow Beach and Katherine Landing) and one in Nevada (Cottonwood Cove). An additional launch ramp is located at Princess Cove on the Arizona side near Katherine Landing. Lake Mohave provides aquatic and riparian habitat for native fish and a variety of introduced game fish, desert wildlife and plants.Credits: National Park Service
