After nearly a year of intense negotiations, California, Nevada and Arizona reached a historic agreement today to use less water from the overdrafted Colorado River over the next three years. The states agreed to give up 3 million acre-feet of river water through 2026 — about 13% of the amount they receive. In exchange, farmers and other water users will receive compensation from the federal government.
The Klamath River begins in Oregon, draining the eastern slope of the Cascade Mountains, and slices through the northwestern corner of California before flowing into the Pacific Ocean. The Colorado River begins in Colorado, draining the eastern slope of the Rocky Mountains, before meandering southwesterly and emptying into Mexico’s Sea of Cortez – if there’s any water left after California and other states have tapped the river for irrigation and municipal supplies.
A deal has been reached to conserve at least 3 million acre-feet of water in the Colorado River through 2026, the Department of the Interior announced on Monday. More than half of that would be saved by the end of 2024.
It’s Earth’s original disrupter — a recurring climate pattern so powerful that it can drive global average temperature to record highs, and generate both cliff-crumbling storms and crop-destroying droughts across the planet.
Now, after a long hiatus, El Niño is showing signs of a strong return in 2023.
Snow is melting earlier, and more rain is falling instead of snow in the mountain ranges of the Western U.S. and Canada, leading to a leaner snowpack that could impact agriculture, wildfire risk and municipal water supplies come summer, according to a new study from the University of Colorado Boulder.

Climate change’s hotter temperatures and society’s diversion of water have been shrinking the world’s lakes by trillions of gallons of water a year since the early 1990s, a new study finds.
A close examination of nearly 2,000 of the world’s largest lakes found they are losing about 5.7 trillion gallons (21.5 trillion liters) a year. That means from 1992 to 2020, the world lost the equivalent of 17 Lake Meads, America’s largest reservoir, in Nevada. It’s also roughly equal to how much water the United States used in an entire year in 2015.
Gov. Gavin Newsom plans to unveil a sweeping package of legislation and sign an executive order Friday to make it easier to build transportation, clean energy, water and other infrastructure across California, a move intended to capitalize on an infusion of money from the Biden administration to boost climate-friendly construction projects.
Americans can likely expect summer temperatures to be even more sweltering than usual, according to the National Oceanic and Atmospheric Administration.
Hotter-than-normal temperatures are possible for much of the U.S., with all of the East Coast, the South, the West Coast and Rockies forecast to sustain scorching conditions, according to the NOAA’s Summer Outlook, released on Thursday.
In 2021, at a Colorado River conference in Las Vegas, the Southern Nevada Water Authority laid out an ambitious and detailed plan to lower per capita water use through conservation. The presentation quantified why deep municipal conservation — limits on decorative grass, pool sizes, golf courses, septic tanks and landscaping — was necessary to adapt to a far drier future.
