Current Water Supply Conditions and Outlook
September 28, 2015
After moving to the Voluntary Stage of their water shortage response plans on August 11, Everett, Seattle, and Tacoma asked customers to reduce their water use by 10 percent to stretch water supplies, for people and fish, to the rainy season.
Water reduction goal met
Over the last six weeks, the region has collectively cut back water use by 14 percent. We appreciate what people have done to cut back and thank them for their efforts. Continued water use reductions are needed until fall rains return in earnest and fill our reservoirs back to normal levels.
As the weather continues to cool, customers should think about what they can do to save water inside their homes.
Indoor water-saving tips for residents
- Reduce showering time
- Check for and fix leaks
- Wash only full loads of laundry and dishes
- Turn off the tap while brushing teeth or shaving
- Don’t pre-rinse dishes
- If purchasing fixtures or equipment, choose water-efficient models
The next round of regional water use reduction results will be released the week of October 7.

Water supply update
We are making operational changes and activating supplementary water supplies – all in an effort to stretch our water supply as far as possible.
Last week, 0.33 inches and 0.39 inches of precipitation were recorded in our Cedar River and South Fork Tolt River watersheds, respectively.
Chester Morse Lake at the Overflow Dike is at elevation 1547.0 feet, about 1.2 feet lower than last week, and about 1.9 feet below its long term average (based on the years 1989 to 2005). Masonry Pool Reservoir at Masonry Dam is at elevation 1514.7 feet, about 0.8 feet higher than last week, and about 22.2 feet below its long term average. The South Fork Tolt Reservoir at the South Fork Tolt Dam is at elevation 1716.4 feet, about 2.0 feet lower than last week, and about 25.8 feet below its long term average. Water releases from reservoir storage are actively being managed for water supply, hydropower and fish habitat management objectives for both the Cedar and South Fork Tolt Rivers.
Water consumption for the previous seven days averaged approximately 117 mgd. That is less than the 127 mgd consumed during the same period last year, and less than the average of 145 mgd used during the same period over the years 1999-2008.
