[29][30], A reprieve from the steady annual decline occurred in 2017 when lake levels rose throughout the year due to heavier than normal snowfall in the Rocky Mountains. The water level in 2015, however, is part of a decade-long decline, and has reached lows not seen since the 1930s when the lake was first filling. The entire Colorado River Basin has been in a drought for 15 years, causing water levels in the reservoir to plummet. There are plenty of tips at the end of the Calculator that will help you find out how to lower your water footprint, a critical action if we’re going to learn to live with the “bathtub ring,” and try to use the Colorado River – and all of our other rivers – sustainably, now and into the future.

In reality, Lake Mead is the largest man-made lake and reservoir in the U.S.A. 3. The lake has remained below full capacity since 1983 due to drought and increased water demand. This photo taken at Lake Mead in February shows the impacts of the prolonged drought on the reservoir, which serves the California water agencies that depend on the Colorado River for some or all of their water. Let’s just say that ensuring the future of drinking water in the city will be a definite challenge. It took 3,250,000 cubic yards of concrete to build, and employed thousands of workers. The next basin to the east is Temple Basin, and following that is Gregg Basin, which is connected to the Temple Basin by the Virgin Canyon. It’s also a great first step in understanding the water scarcity that everyone in the Southwest faces.

To ensure sufficient future access to water from the lake, the city is nearing completion of a new tunnel that will draw water from an elevation level of 875 feet, giving the city access to cooler water from a deeper part of the lake (cooler, deeper water generally has a higher quality). Select the graph you wish to view: [42] If water levels continue to drop, Hoover Dam would cease generating electricity when the water level falls below 950 feet (290 m) and the lake would stabilize at a level of 895 feet (273 m) when the water reaches the lowest water outlet of the dam. The longer-term record shows drops in water elevation associated with a drought in the mid-1950s and again in the mid-1960s. The Powwow. Water levels were so low at Lake Mead in 2015 that ruins of the St. Thomas ghost town became exposed. Tweet . Lake Mead hit a record high elevation of 1,220 feet above sea level in the summer 1941, just five years after completion of the dam, but the level has fluctuated and been in decline ever since. Hoover Dam is required to release 9 million acre feet (11,000,000 ML) of water each year, with the difference made up by tributaries that join the Colorado below Glen Canyon or flow into Lake Mead. Due to drought conditions since the early 2000s, the water level at Lake Mead has dropped 130 feet and current infrastructure was in danger of becoming inoperable.

This lake is actually a man-made reservoir that was created as a result of the construction of the Hoover Dam. Since 2000, meltwater has raised the lake’s surface only one or two feet each spring, while summer water use has lowerd the level about 20 feet each year. The water level in Lake Mead sits at 1,083 feet (330 meters). Boating is the most popular. It is the largest reservoir in the United States in terms of water capacity. Melting snow raises the lake in the spring, while evaporation and siphoning of irrigation water lowers the level in summer.

Take care when parking and walking along shoreline areas. At lower water levels, a high-water mark or "bathtub ring" is visible in photos that show the shoreline of Lake Mead. The U.S. Bureau of Reclamation (BOR) reports a high water line of 1,229.0 feet but defines an elevation of 1,221.4 (the elevation of the top of the spillway crest at Hoover Dam) as maximum lake storage capacity and 1,219.6 feet elevation as “operationally full.”
