Portland General Electric’s North Fork Dam, on the Clackamas River southeast of Portland, is a thin, variable-radius concrete arch dam with a maximum height of 207 feet and a thickness varying from 32 feet at the base to 8 feet at the crest. The spillway is a 200-foot-long gated ogee-type structure with a 250-foot-long reinforced concrete chute discharging into the tailrace. The spillway is controlled by three, 50-foot-wide by 37.5-foot-high tainter gates. The powerhouse contains two generating units capable of producing 54 MW of power. A fish ladder is located on right side of the dam.
