Current Water Supply Conditions
September 13, 2016
Last week 0.76 inches and 0.60 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 1551.2 feet, about 1.2 feet lower than last week, and about 2.0 feet above its long term average (based on the years 1989 to 2005). Masonry Pool Reservoir at Masonry Dam is at elevation 1550.8 feet, about 1.2 feet lower than last week, and about 12.0 feet above its long term average. The South Fork Tolt Reservoir at the South Fork Tolt Dam is at elevation 1741.4 feet, about 1.6 feet lower than last week, and about 2.2 feet below its long term average. Water releases from reservoir storage are actively being managed for water supply, hydropower, fish habitat and flood management objectives for both the Cedar and South Fork Tolt Rivers.
Water consumption for the previous seven days averaged approximately 129 million gallons per day (mgd). That is more than the 123 mgd consumed during the same period last year, and less than the average of 157 mgd used during the same period over the years 1999-2014.
