Lake Tapps Reservoir Levels Update

Due to no precipitation and low river flows, the reservoir level has dropped slightly to 542.3โ€™ (as of 2:30 on 9/11/20). Cascade is doing everything it can to add water to the reservoir, but until we get meaningful precipitation, the reservoir may continue to lower some. With precipitation, Cascade expects to continue to maintain the reservoir within the agreed-upon recreational level of 541.5 โ€™- 543โ€™ until September 30 and possibly through October 31, if conditions allow.
