The Lake Tapps Reservoir remains full, and Cascade is allowing the current fall weather to slowly bring the level to the minimum recreation levels (election 541.5 feet) well into October.

It will remain at that level for the remainder of

Lake Tapps Opens Today!

July 02, 2015

Cascade is officially opening Lake Tapps Reservoir to all recreation effective immediately. Remember, this water is cold, and you may encounter stumps, floating debris or submerged hazards in the reservoir.   This opening has been made possible by Cascade’s project for the Corps in which water was twice stored behind Mud Mountain Dam and then released. After state-mandated in-steam flows have been met, water is diverted into Lake Tapps Reservoir. Some additional water will come in this weekend.  Law enforcement will be on patrol.
