Lake Tapps Reservoir to Rise to 543 Feet

This week Cascade will raise the Lake Tapps Reservoir to approximately elevation 543 feet, the maximum allowable level at which Cascade can operate. The reservoir will reach 543 feet on or around May 15 and will then be drawn down slightly, using the leakage from the reservoir, to normal recreational summer levels.
