Lake Powell and Lake Mead Fall to Lowest Combined Levels on Record

Federal managers are conducting emergency transfers and paying for conservation as they prepare short-term mandatory cuts to avert hydropower loss and water delivery failures next year.

Overview

  • This week researchers and government data showed the two reservoirs that anchor the Colorado River system are at record-low combined storage, with Lake Powell about 23% full and Lake Mead about 27% full.
  • The Bureau of Reclamation has begun emergency transfers from upstream reservoirs and accepted a $65 million agreement with the Metropolitan Water District to keep water in Lake Mead as temporary relief.
  • Officials warn Lake Powell could hit its minimum power pool by next spring, a level that would stop hydroelectric generation and complicate downstream deliveries from Glen Canyon Dam.
  • Seven-state negotiations over long-term cuts remain deadlocked, so federal managers are expanding paid conservation programs and preparing short-term mandatory cut plans and new operating guidance.
  • Local economies and recreation are already feeling the impact as marinas and boat ramps are moved or extended, costly access projects are launched, and farmers and cities face tougher water and power planning.
