Historical Background
Lake Mead, located in Clark County, Nevada and Mohave County, Arizona on the Colorado River, is the sixteenth largest man-made lake in the world. Its surface area is 164,000 acres with a storage volume of 26,134,000 acre-feet. The National Park Service originally named Lake Mead the "Boulder Dam Recreation Area" in 1936 preceding Hoover Dam's (Boulder Dam) construction, existing as the United State's largest reservoir at the time. In 1947, the National Park Service then renamed the reservoir Lake Mead after Dr. Elwood Mead, who was the Commissioner of the Bureau of Reclamation from 1924 to 1936. In 1964, Public Law 88-639 established the Lake Mead National Recreation Area under the jurisdiction of the National Park Service. Over time, Lake Mead's water level fluctuated from its highest point in July 1983 at 1,225 feet, down to its current height at 1,083 feet in 2019. However, Lake Mead still exists as one of the largest reservoirs in the United States with depths surpassing 300 feet. Lake Mead National Recreation Area is also
- Page 3- Guide to the Morgan Sweeney Photograph Collection the sixth most visited park in the National Park System and the premier inland water recreation area in the Western United States. The United States Bureau of Reclamation began construction on Hoover Dam in the Black Canyon, located on the Nevada-Arizona border, in 1932. The Black Canyon Project dammed the Colorado River and constructed a hydroelectric power plant to provide electricity to the southwestern United States. The dam created the reservoir known as Lake Mead. Originally called Boulder Dam, the government officially renamed it Hoover Dam in 1947 in honor of President Herbert Hoover. Sources: "Hoover Dam."
