The Greater Bonney Lake Historical Society and Cascade Water Alliance will dedicate a new historic marker at the White River Project powerhouse on Saturday.
The dedication starts at 11 a.m. The public is invited.
Lake Tapps, now a popular East Pierce County recreation spot, was created as part of the White River hydroelectric project that launched in 1910.
The project eventually shut down, and Cascade – a group of King County cities and water and sewer districts – bought it in December 2009. The group plans to eventually use Lake Tapps as a regional drinking water source.
Cascade paid for the historic marker, which is the 11th coordinated by the historical society.
The powerhouse is at 2111 East Valley Highway, Sumner.
