Federal officials have a sobering forecast for the Colorado River Basin: Lake Mead, the nations largest reservoir which serves millions of people in the Southwest, will likely drop another 12 feet by this fall. The lake, a reservoir of the Colorado River, formed by the Hoover Dam, provides water to 25 million people in California, Nevada and Arizona, but it has been facing the effects of an ongoing megadrought. These lake-wide averages are based on a select set of U.S. and Canadian station data as determined by the Coordinating Committee. Results from CRMMS run with ESP are referred to as CRMMS-ESP. Lake Mead is on the border of Nevada and Arizona. The reservoirwhich stretches across Nevada and Arizona, on the Colorado Riveris relied upon by 25 million people living in the region. Jennifer Pitt, the Colorado River program director with the National Audubon Society, an environmental organization, previously told Newsweek: "To refill the Colorado River reservoirs, you would need three average years of snowfall without any water use. CRMMS Ensemble Mode is driven by an ensemble of monthly unregulated streamflow forecasts developed by the National Weather Service Colorado Basin River Forecasting Center (CBRFC) using the Ensemble Streamflow Prediction (ESP) method. Lake Mead's water levels could reach an all-time low in 2023, projections from the Bureau of Reclamation show. Its a point we want to avoid (that is, if we can). The region continues to grapple with mostly dry conditions, and the water levels are still incredibly low compared to the same point last year. Join half a million readers enjoying Newsweek's free newsletters. The drought in the Western U.S. has been ongoing for two decades.

The reservoir is also formed by the Hoover Dam, which produces about 4 billion kilowatt-hours of hydroelectric power every year. "[Additionally,] many of the current policies that govern Colorado River allocations, including the DCP [drought contingency plan] and other shortage-sharing guidelines, expire in 2026, so the states and federal government are simultaneously beginning a process to develop rules for the next 20 years of Colorado River management that can help mitigate some of these issues.

If the forecast indicates Lake Meads water level will be below 1,050 feet come January 1, the Southwest will move into the second tier of unprecedented water cuts that will deepen the impacts for cities, industry and tribal water users. If that forecast holds in next months report, which is what federal officials will use to determine cuts for 2023, the Southwest will be subject to a Tier 2 water shortage and the fresh cuts that come with it starting in January. Updated These projections rely on future hydrology from the CBRFCs ESP method and may not be representative of the full range of future possibilities that could occur; other hydrology methods may result in a wider range of future hydrology and elevations. Experts predict that in a few years, the lake's water levels could be as low as 895 feet, which would be too low to flow past the dam. Current conditions data typically are recorded at 15-60 minute intervals, stored onsite, and then transmitted to the Nevada Water Science Center Office hourly.
