WASHINGTON \u2013 U.S. officials on Monday declared the first-ever water shortage from a river that serves 40 million people in the West, triggering cuts to some Arizona farmers next year amid a gripping drought.<\/p>\n

Water levels at the largest reservoir on the Colorado River \u2013 Lake Mead \u2013 have fallen to record lows. Along its perimeter, a white \u201cbathtub ring\u201d of minerals outlines where the high water line once stood, underscoring the acute water challenges for a region facing a growing population and a drought that is being worsened by hotter, drier weather brought on by climate change.<\/p>\n

States, cities, farmers and others have diversified their water sources over the years, helping soften the blow of the upcoming cuts. But if current conditions persist \u2013 or intensify \u2013 additional cuts in coming years will be more deeply felt.<\/p>\n

Lake Mead was formed by building Hoover Dam in the 1930s. It is one of several human-made reservoirs that store water from the Colorado River, which supplies drinking water, irrigation for farms and hydropower to Arizona, California, Colorado, Nevada, New Mexico, Utah, Wyoming and parts of Mexico.<\/p>\n

But water levels at Lake Mead and Lake Powell<\/a>, the river\u2019s two largest reservoirs, have been falling for years and faster than experts predicted. Scorching temperatures and less melting snow in the spring have reduced the amount of water flowing from the Rocky Mountains, where the river originates before it snakes 1,450 miles southwest and into the Gulf of California.<\/p>\n

\u201cWe\u2019re at a moment where we\u2019re reckoning with how we continue to flourish with less water, and it\u2019s very painful,\u201d said Sarah Porter, director of the Kyl Center for Water Policy at Arizona State University.<\/p>\n

How is the river water shared?<\/div>\n

Water stored in Lake Mead and Lake Powell is divvied up through legal agreements among the seven Colorado River basin states, the federal government, Mexico and others. The agreements determine how much water each gets, when cuts are triggered and the order in which the parties have to sacrifice some of their supply.<\/p>\n

Under a 2019 drought contingency plan, Arizona, Nevada, California and Mexico agreed to give up shares of their water to maintain water levels at Lake Mead. The voluntary measures weren\u2019t enough to prevent the shortage declaration.<\/p>\n

Who does Lake Mead serve?<\/div>\n

Lake Mead supplies water to millions of people in Arizona, California, Nevada and Mexico.<\/p>\n

Cuts for 2022 are triggered when predicted water levels fall below a certain threshold \u2013 1,075 feet above sea level, or 40% capacity. Earlier this summer, Lake Mead\u2019s elevation hit its lowest point since being filled in the 1930s at 1,068 feet.<\/p>\n

Further rounds of cuts are triggered when projected levels sink to 1,050, 1,045 and 1,025 feet.<\/p>\n

Eventually, some city and industrial water users could be affected.<\/p>\n

Lake Powell\u2019s levels also are falling, threatening the about 5 billion kilowatt hours of electricity generated each year at the Glen Canyon Dam.<\/p>\n

Colorado, New Mexico, Utah and Wyoming get water from tributaries and other reservoirs that feed into Lake Powell. Water from three reservoirs in those states has been drained to maintain water levels at Lake Powell and protect the electric grid powered by the Glen Canyon Dam.<\/p>\n

Which states will be affected by the cuts?<\/div>\n

In the U.S., Arizona will be hardest hit and lose 18% of its share from the river, or 512,000 acre-feet of water. That\u2019s around 8% of the state\u2019s total water use<\/a>.<\/p>\n

An acre-foot is enough water to supply one to two households a year.<\/p>\n

Nevada will lose about 7% of its allocation, or 21,000 acre-feet of water. But it will not feel the shortage because of conservation efforts and alternative sources of water.<\/p>\n

California is spared from immediate cuts because it has more senior water rights than Arizona and Nevada.<\/p>\n

Mexico will see a reduction of about 5%, or 80,000 acre-feet.<\/p>\n

Who in those states will see their water supply cut?<\/div>\n

Farmers in central Arizona<\/a>, who are among the state\u2019s largest producers of livestock, dairy, alfalfa, wheat and barley, will bear the brunt of the cuts. Their allocation comes from water deemed \u201cextra\u201d by the agency that supplies water to much of the region, making them the first to lose it during a shortage.<\/p>\n

As a result, the farmers will likely need to fallow land \u2013 as many already have in recent years because of persisting drought \u2013 and rely even more on groundwater, switch to water-efficient crops and find other ways to use less water.<\/p>\n

Water suppliers have planned for the shortage declaration by diversifying and conserving their water supply, such as by storing water in underground basins. Still, water cuts make it harder to plan for the future.<\/p>\n

The Central Arizona Project, which supplies water to Arizona\u2019s major cities, will no longer bank river water or replenish some groundwater systems next year because of the cuts.<\/p>\n

\u201cIt\u2019s a historic moment where drought and climate change are at our door,\u201d said Chuck Cullom with the Central Arizona Project.<\/p>\n

Cities such as Las Vegas, Phoenix and Tucson, and Native American tribes are shielded from the first round of cuts.<\/p>\n

Can the decline of Lake Mead be reversed?<\/div>\n

Water levels at the reservoir have been falling since 1999 because of the dry spell enveloping the West and increased water demand. With weather patterns expected to worsen, experts say the reservoir may never be full again.<\/p>\n

Though Lake Mead and Lake Powell could theoretically be refilled, planning for a hotter, drier future with less river water would be more prudent, said Porter with Arizona State University.<\/p>\n
