Lake Mead hits record low water level, threatening Nevada supply
Lake Mead, the United States' largest reservoir, recorded a new historic low water elevation of about 1,040.5 feet above sea level, surpassing the previous record of 1,040.58 feet set in July 2022. The drop marks the lowest level since the 1930s and leaves the lake at roughly 27 % of its original storage capacity, more than 188 feet below full pool.
Prolonged drought, a weak snowpack and higher-than‑average winter temperatures have reduced inflows from the Colorado River basin, which supplies water to up to 40 million people in the western U.S. and Mexico. The decline threatens municipal water supplies for Southern Nevada, including Las Vegas, agricultural deliveries downstream, and hydro‑electric generation at the Hoover Dam.
As the water recedes, submerged mountain terrain and hazardous obstacles are re‑emerging, creating new safety concerns for boaters. Officials from the Southern Nevada Water Authority and the U.S. Bureau of Reclamation are monitoring the situation and preparing for tighter water‑allocation negotiations and conservation measures.
