Seattle’s Water Supply: Good

Seattle’s current water supply conditions at its reservoirs are good.

Seattle’s regional source of water supply comes from two rain- and snow-fed watersheds in the Cascade Mountains, the Cedar River Watershed and the Tolt River Watershed.  This is the time when mountain streamflows from the rain and spring season snowmelt are refilling our storage reservoirs. 

Water supply reservoir water levels are now above the long-term average for this time of the year.  Water releases from reservoir storage are actively being managed to balance water supply, fish habitat, hydropower and flood management objectives for both the Cedar and South Fork Tolt Rivers.

Water consumption for the previous seven days averaged approximately 114 mgd.  That is less than the 120 mgd consumed during the same period last year, and less than the average of 133 mgd used during the same period over the years 1999-2008. 

Seattle Public Utilities asks its customers to continue to use water wisely.
