Water Supply Advisory Committee

 Ecology home | Water supply | Statewide conditions

Last revised: December 6, 2017

The Water Supply Availability Committee (WSAC) is a group of experts from state and federal agencies who evaluate statewide water supply conditions. We regularly convene this group. Findings from their meetings can be found on the statewide conditions page.

WSAC's membership includes representatives from:

  • Department of Ecology
  • Office of Washington State Climatologist
  • U.S. Geological Survey
  • National Weather Service
  • Natural Resources Conservation Service
  • U.S. Bureau of Reclamation
  • U.S. Army Corps of Engineers
  • Bonneville Power Administration

If conditions warrant, this committee can convene the Executive Water Emergency Committee (EWEC), which is made of state agency leaders with a stake in water supplies. These leaders assess findings from WSAC and can recommend the governor consider an emergency drought declaration.
