Electron sits along the Puyallup River just northeast of Lake Kapowsin and is the site of the Electron Hydroelectric Project, a power plant operated by Puget Power. Above the plant, 10.1 miles upriver, is the Electron Diversionary Dam, which runs water to the power plant via a wooden flume.^[2] The dam and power plant project was constructed in 1903-04 and began operation on April 12, 1904. Electron was the site of a CCC camp in the 1930s. A mudslide destroyed the original powerhouse in 1936; rebuilding was partially completed in 1937 and fully rehabilitated in 1941. There is a small town park in Electron.
