Each year the water level in Lake Tapps is managed to achieve appropriate recreational levels during the late spring, summer and early fall. In late fall through winter, the lake levels are lowered to allow homeowners to repair and maintain docks and bulkheads and also to provide for dike maintenance/repair and control of milfoil. Cascade will consult with the Lake Tapps Community Council annually to determine when to begin refill in the spring, the appropriate recreational level, when to begin fall drawdown and the appropriate drawdown level.
February 2010
The Lake Tapps' current elevation is about 533 feet.
In late 2009, early 2010, Cascade lowered the reservoir's water level by about 12 to 14 feet. A key goal of the drawdown is to kill milfoil in the lake's shallower areas by exposing the lake bottom grass to freezing wintertime temperatures. The annual drawdown is also designed to ensure that waves from severe winter storms do not overtop the reservoir’s dikes. This year's drawdown was lower than anticipated to allow for repair work along Dike 10 to be completed.
Refilling of the reservoir began approximately Feb. 15, 2010 with the goal of returning the lake to its full, summer recreational level by mid-April. This schedule may be affected by severe winter weather and flood damage to the White River diversion dam near Buckley.
