The man-made lakes that store water supplying millions of people in the U.S. West and Mexico are projected to shrink to historic lows in the coming months, dropping to levels that could trigger the federal government’s first-ever official shortage declaration and prompt cuts in Arizona and Nevada.
The U.S. Bureau of Reclamation released 24-month projections this week forecasting that less Colorado River water will cascade down from the Rocky Mountains through Lake Powell and Lake Mead and into the arid deserts of the U.S. Southwest and the Gulf of California. Water levels in the two lakes are expected to plummet low enough for the agency to declare an official shortage for the first time, threatening the supply of Colorado River water that growing cities and farms rely on.
It comes as climate change means less snowpack flows into the river and its tributaries, and hotter temperatures parch soil and cause more river water to evaporate as it streams through the drought-plagued American West.
The agency’s models project Lake Mead will fall below 1,075 feet (328 meters) for the first time in June 2021. That’s the level that prompts a shortage declaration under agreements negotiated by seven states that rely on Colorado River water: Arizona, California, Colorado, Nevada, New Mexico, Utah and Wyoming.
The April projections, however, will not have binding impact. Federal officials regularly issue long-term projections but use those released each August to make decisions about how to allocate river water. If projections don’t improve by then, the Bureau of Reclamation will declare a Level 1 shortage condition. The cuts would be implemented in January.
Arizona, Nevada and Mexico have voluntarily given up water under a drought contingency plan for the river signed in 2019. A shortage declaration would subject the two U.S. states to their first mandatory reductions. Both rely on the Colorado River more than any other water source, and Arizona stands to lose roughly one-third of its supply.
Water agency officials say they’re confident their preparation measures, including conservation and seeking out alternative sources, would allow them to withstand cuts if the drought lingers as expected.
“The study, while significant, is not a surprise. It reflects the impacts of the dry and warm conditions across the Colorado River Basin this year, as well as the effects of a prolonged drought that has impacted the Colorado River water supply,” officials from the Arizona Department of Water Resources and Central Arizona Project said in a joint statement.
In Nevada, the agency that supplies water to most of the state has constructed “straws” to draw water from further down in Lake Mead as its levels fall. It also has created a credit system where it can bank recycled water back into the reservoir without having it count toward its allocation.

water shortage out of your water faucet from your house only. No shortage when you buy from a store. Or if you own a yacht with a water maker
Now govt. agencies that deal with weather have known for years that the Grand Solar Minimum, likely the main cause of this La Nina cycle (cold Pacific, which causes ocean water to dissipate less thus forming fewer rain clouds), was coming in 2018 and lasting possibly until 2023 or later…in other words, they’ve known for years (since they study sun spots and solar cycles, right?) that another 1950s-like serious drought cycle was coming to the Southwest–and did nothing to ameliorate this present situation. NO EXCUSES! And then there are the chemtrails…. Right. Kill off millions of wildlife animals (starvation and lack of water) in order to “force” us in the rural remote southwest into stack ‘n packs. Also killing off bees, who need brush pollen to make honey and re-pollinate… Revelation 11:18 comes to mind….
