Above the plant, 10.1 miles upriver, is the Electron Diversionary Dam, which runs water to the power plant via a wooden flume. 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. In 1936, the powerhouse was destroyed by a mudslide; rebuilding was partially completed in 1937 and fully completed in 1941. There is a small town park in Electron.
