Current Water Supply Conditions and Outlook
After unusually hot weather, the region’s all-time driest May-July, and in preparation of a potentially drier-than-normal fall, Everett, Seattle, and Tacoma moved to the second stage of their water shortage response plans on August 11 – voluntary reduction.
The three cities are working together to manage water supplies for people and fish during the potential water shortage. They are asking customers to help by voluntarily reducing water use by 10%.
The best ways you can reduce your water use include:
- Let your lawn go dormant and limit plant watering to twice a week.
- Water plants before 8 a.m. or after 7 p.m.
- Reduce your showering time.
- Check for and fix leaks, including checking your toilets for silent leaks.
- Wash only full loads of laundry and dishes.

Water supply update — August 24, 2015
We are making operational changes and activating supplementary water supplies – all in an effort to stretch our water supply as far as possible.
If conditions worsen, we may move to the mandatory phase of water shortage response and require customers to further reduce the amount of water they normally use each day.
Last week, 0.06 inches and 0.02 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 1548.9 feet, about 0.3 feet lower than last week, and about 2.5 feet below its long term average (based on the years 1989 to 2005). Masonry Pool Reservoir at Masonry Dam is at elevation 1511.9 feet, about 2.9 feet lower than last week, and about 33.8 feet below its long term average. The South Fork Tolt Reservoir at the South Fork Tolt Dam is at elevation 1725.1 feet, about 3.0 feet lower than last week, and about 23.6 feet below its long term average. Water releases from reservoir storage are actively being managed for water supply and fish habitat management objectives for both the Cedar and South Fork Tolt Rivers. Streamflows in both the South Fork Tolt River and Cedar River are being held at guaranteed flows for this time of the year and are providing full protection for incubating salmon and steelhead trout.
Water consumption for the previous seven days averaged approximately 164 mgd. That is more than the 162 mgd consumed during the same period last year, and less than the average of 182 mgd used during the same period over the years 1999-2008.
