When Alder Dam was completed in 1945 it was one of the tallest dams in the nation, measuring 330 feet in height and 1,600 feet in length. The powerhouse has two 25,000-kilowatt turbine generators that produce about 228 million kilowatt-hours of electricity each year. Alder Dam formed seven-mile-long Alder Lake. With 28 miles of shoreline and 3,065 acres of reservoir area at maximum elevation, Alder Lake is an inviting spot for boaters, water skiers, anglers and picnickers.
