Lake Tapps 543′ Level Update

As it does every year, Cascade will be bringing the Lake Tapps Reservoir level up to its highest allowable level of 543′ on Wednesday, May 9, for about 24 hours. Residents should be prepared for this increased level. Following this, reservoir levels for the remainder of the summer and through September will be around 542.5′.  Cascade owns Lake Tapps for eventual municipal water supply. Click here for the history of the maximum and minimum reservoir elevations.
