Lake Mead, nation's largest reservoir, reaches its lowest water level on record
Key Points:
- Lake Mead, the largest U.S. reservoir by storage capacity, reached a record low water level of 1,040.50 feet on Thursday, breaking the previous low set in July 2022.
- The reservoir, formed by the Hoover Dam on the Colorado River and supplying water to millions, has seen declining levels due to prolonged drought and exceptionally low snowpack in the Colorado River Basin.
- Lake Powell, the second largest reservoir, is also nearing a record low elevation of 3,521.43 feet, approaching a critical level for hydropower production.
- The Colorado River Basin provides water and hydropower to up to 40 million people across seven western U.S. states and Mexico, making these low reservoir levels a significant concern.
- Hydrologists attribute the declining water levels to ongoing drought conditions and warmer-than-normal winter temperatures that prevented snow accumulation and subsequent snowmelt feeding into the reservoirs.
