The nation's largest reservoir is in crisis — 40 million Americans depend on it.
Created by Hoover Dam in 1936, Lake Mead is the largest US reservoir. It sits on the Colorado River, supplying water to the American Southwest.
A 22-year megadrought — the worst in 1,200 years — combined with over-allocation drove the reservoir to a historic low in 2022.
Las Vegas, Phoenix, Los Angeles, and Tucson depend on Lake Mead. Arizona and Nevada face mandatory cuts. Imperial Valley farmers face irrigation curtailments.
After a wet 2023, levels partially recovered. But 2025-2026 brought renewed drought. The Bureau of Reclamation issued conservation guidance through 2027.
UCLA and NOAA scientists confirm climate change causes 30-50% of the drought severity. Rising temperatures increase evaporation and reduce snowpack — Lake Mead's main water source.
Las Vegas recycles 99% of indoor water. Nevada farms switched to drip irrigation. The IRA allocated $4B for Western water conservation. Desalination plants planned for California.
Fix leaks, replace lawns with drought-tolerant plants, install smart irrigation timers, and upgrade to water-efficient appliances. Conservation is survival in the American West.
