Construction of the St. Stephen Powerhouse Dam, a rediversion canal connecting Lake Moultrie to the Santee River and a hydroelectric power plant, is authorized by Congress. Today, the project reduces sedimentation in the Charleston Harbor from 10 to 2 million cubic yards, saving taxpayers millions in annual dredging costs. The plant also supplies power to more than 40,000 homes, and its fish lift passes 750,000 fish every year.
