Lake Mead is a reservoir formed by the Hoover Dam on the Colorado River in the Southwestern United States. It is located in the states of Nevada and Arizona, 24 mi (39 km) east of Las Vegas. It is the largest reservoir in the US in terms of water capacity. Lake Mead provides water to the states of Arizona, California, and Nevada as well as some of Mexico, providing sustenance to nearly 20 million people and large areas of farmland.[1]
At maximum capacity, Lake Mead is 112 miles (180 km) long, 532 feet (162 m) at its greatest depth, has a surface elevation of 1,229 feet (375 m) above sea level, has a surface area of 247 square miles (640 km2), and contains 28.23 million acre-feet (34.82 km3) of water.
The lake has remained below full capacity since 1983 owing to drought and increased water demand.[2][3][4] As of May 31, 2022, Lake Mead held 26.63% of full capacity at 7.517 million acre-feet (9,272,000 megaliters), having dropped in June 2021 below the reservoir's previous all-time low of 9.328 million acre-feet (11,506,000 megaliters) recorded in July 2016, and never returning to that level.[5] In a draft 2022 Colorado River annual operating plan, released by the U.S. Bureau of Reclamation, a "Shortage Condition" was expected to be declared for 2022, due to the lake level falling below 1,075 feet (327.7 m), which would have resulted in a projected 4.44% curtailment in downstream water delivery.[6]
