Water from Alder Lake is sent into two generators at the base of the dam, each of which produces 25,000 kilowatts for a total nameplate capacity of 50,000 kilowatts.〔 Two miles downstream is LaGrande Dam, site of the first dam in the area, dating from 1912, and rebuilt in 1945 along with Alder's construction. Most of the energy produced at the dam is sent to the city of Tacoma, about north. Both Alder and LaGrande dams are owned and operated by Tacoma Power. ==References==
