Lake Mohave is a reservoir formed by Davis Dam on the Colorado River, which defines the border between Nevada and Arizona in the United States. The lake lies at an elevation of 647 feet (197 m) near Laughlin, Nevada and Bullhead City, AZ, about 67 miles (108 km) downstream from Hoover Dam. The lake and adjacent lands forming its shoreline are part of the Lake Mead National Recreation Area administered by the U.S. National Park Service.
