Colorado River States Face Tuesday Cutoff for New Rules as Lakes Mead and Powell Hover Near 30% Capacity

Federal officials are prepared to impose operating plans if the seven states fail to agree by November 11.

Overview

  • Negotiators say they are close on broad concepts but still divided over how to run the reservoirs and whether all states must take mandatory cuts in dry years.
  • The Interior Department set a November 11 deadline for a consensus framework, and failure to agree could trigger a federal backstop for post-2026 operations.
  • Colorado’s Becky Mitchell says current rules are not working and notes both reservoirs are roughly 30% full as the 2007 interim guidelines approach their 2026 expiration.
  • Colorado Springs draws about half its supply from the basin and, with reuse, nearly 70%, and it is modeling risks that include a decade with a 20% reduction in Colorado River sources.
  • Utah has expanded measurement and monitoring since 2023 with a $1 million infrastructure project and $650,000 in annual funding, as farmers warn that 10%–20% allocation cuts would strain operations.
