Perched on a sheer cliff more than 400 feet above the Nisqually River, which tumbles and froths through a 20-foot channel below. A lodge, a village store, and a gas station cling tenaciously to the slope beside the highway, trees hiding the canyon from view. Here is the city of Tacoma’s hydroelectric plant below the reservoir, from which four penstocks carry water to the battery of huge turbines in the powerhouse 425 feet below. Completed in 1912, the plant was one of the earliest municipally owned projects in the State. It has a capacity of 25,600 kilowatts.
