The water level of Lake Mead at the Hoover Dam is set to meet its lowest level on record as California's megadrought leave millions under emergency rations.
On Thursday, Lake Mead's water level is projected to hit elevation 1,071.61 feet, sinking to it's lowest elevation on record since the 1930's, said a Bureau of Reclamation spokeswoman.
Thursday's level is about four feet below the level that would trigger a federal declaration of a water shortage which would cut water supplies to Arizona, Nevada and Mexico.
Arizona could have its supply cut by 320,000 acre-feet, Aaron said. That is a year's supply for nearly 1 million households, according to the Arizona Department of Water Resources.
Lake Mead, formed in the 1930s from the damming of the Colorado River at the Nevada-Arizona border about 30 miles east of Las Vegas, is the largest reservoir in the United States.

It is crucial to the water supply of 25 million people including in the cities of Los Angeles, San Diego, Phoenix, Tucson and Las Vegas, Reuters reported.
The Hoover Dam is a concrete arch-gravity dam constructed in the 1930's in the Black Canyon of the Colorado River, which provides drinking water to Arizona, Nevada, and part of Mexico.
The Dam generates electricity for parts of Arizona, California and Nevada and as the water in Lake Mead drops, so does the dam's electrical output.
On average, the dam usually produces about 2,074 megawatts, which is enough electricity for about 8 million people, according to the Western Area Power Administration.
Tuesday's capacity was just 1,567 megawatts, a drop of about 25 percent, CNN reported.
'Every foot of lake level decline means about 6 (megawatt) of lost capacity,' Aaron told CNN.
Aaron added that while the lake's water level is expected to reach a new lows this week, its excepted to continue dropping.
'We anticipate the elevation of Lake Mead to continue to decline until November 2021,' Aaron said.
The drought that has brought Lake Mead low has gripped California, the Pacific Northwest, the Great Basin spanning Nevada, Oregon and Utah, plus the southwestern states of Arizona and New Mexico and even part of the Northern Plains.

The latest data from the U.S. Drought Monitor released on Thursday showed that more than half of the western U.S. is either in an 'extreme' or 'exceptional drought.'
Droughts are a recurring natural hazard but made worse recently by an accumulation of extremely dry years for most of this century. Scientists say human-influenced climate change has exacerbated the situation.
The rains that deluged the West at the end of 2015 - before the previous low-water mark was set at Lake Mead - were a mere respite from what is now a 22-year drought, the driest period in 115 years of record-keeping by the U.S. Bureau of Reclamation, which manages water resources in the Western states.
Dramatic images show the impact the drought has had on Folsom Lake, a reservoir in Sacramento which has reached its lowest water levels since 1977, the Sacramento Bee reported.
For the last six decades the lake maintained 85 percent capacity, roughly 830,000 acre-feet-of-water, by the end of May.
At the end of May this year, Folsom Lake contained only 361,000 acre-feet of water, the equivalent to 37 percent capacity, the Bee reported.
Last month California Governor Gavin Newsom issued a drought emergency proclamation for 41 of the state's 58 counties, empowering the state to take greater control over water resources, Reuters reported.

On Wednesday nearly two million people in the San Francisco Bay Area were placed under a water shortage emergency as mandatory water restrictions have been issued for Santa Clara County, CNN reported.
'We can't afford to wait to act as our water supplies are being threatened locally and across California,' Tony Estremera, director of the Santa Clara Valley Water District, said in a statement. 'To better deal with these threats and the emergency they are causing, today my fellow Board Members and I unanimously declared a water shortage emergency condition in Santa Clara County.'
The deepening drought coincides with the state's summer fire season, leading to concerns from California fire officials.
The extra dry conditions means most of the state faces an increased chance of large and possibly destructive fires for several more months, the Washington Post reported.
