Lake Mead Drops to Record Low as Federal Cut Plan Looms

Federal managers say holding more water in Lake Powell to protect dams will require multi-year cuts that shrink deliveries, reducing Hoover Dam power.

Overview

  • Lake Mead fell to about 1,040.5 feet on Friday, Aug. 7, 2026, the lowest recorded elevation since the reservoir was filled in the 1930s.
  • Federal officials announced a July 31 plan that could force Arizona, California and Nevada to cut as much as 3 million acre-feet over multiple years.
  • The Bureau of Reclamation is holding extra water in Lake Powell to protect upstream infrastructure, a step officials say is already accelerating declines at Lake Mead and could cut Hoover Dam hydropower by roughly 40 percent.
  • Arizona officials warn that large mandatory cuts could leave the Central Arizona Project canal short or dry, threatening municipal supplies for Phoenix and irrigation for farms.
  • More than two decades of warming, low mountain snowpack and an over-allocated river have driven the decline, and federal forecasts project repeated new record lows through 2028 unless flows or water use change.
