Conditions and Outlook
Our overall water supply situation and outlook is good.
Last week, 0.44 inches and 0.68 inches of precipitation were recorded in our Cedar and South Fork Tolt River watersheds, respectively.
Chester Morse Lake at the Overflow Dike is at elevation 1551.5 feet, about 1.1 feet lower than last week, and about 0.8 feet above its long term average (based on the years 1989 to 2005). Masonry Pool Reservoir at Masonry Dam is at elevation 1550.1 feet, about 2.0 feet lower than last week, and about 1.3 feet above its long term average. The South Fork Tolt Reservoir at the South Fork Tolt Dam is at elevation 1753.1 feet, about the same as last week, and about 1.9 feet above its long term average. Water releases from reservoir storage are actively being managed for water supply, fish habitat and flood management objectives for both the Cedar and South Fork Tolt Rivers.
Water consumption for the previous seven days averaged approximately 104 mgd. That is more than the 103 mgd consumed during the same period last year, and less than the average of 117 mgd used during the same period over the years 1999-2008.
Sockeye salmon have nearly completed spawning in the mainstem Cedar River. Coho salmon continue to spawn in the Cedar and Tolt basins. Coho spawning activity typically peaks in November or December and continues into February.
Adult summer-run steelhead continue to hold in the Tolt River basin. Most of these fish move into the upper reaches of the South Fork Tolt River where they hold through the summer and fall, then spawn during the following winter and spring. Young coho, steelhead, resident and adfluvial trout are rearing in the Cedar. Young steelhead and coho are rearing in the South Fork Tolt.
