Additional Details:
The Hydro-Electric Plant on the Susquehanna River at Conowingo, Maryland, which is part of the Philadelphia Electric Company System, is one of the largest water-power developments in the United States. The dam, almost a mile across and surmounted by a highway bridge 20 feet wide, forms a lake fourteen miles long. The initial installation is 378,000 HP which will eventually be increased to 594,000 HP. A 220,000 volt transmission line carries current to Philadelphia. Work was started March 8, 1926 and the first units were put into operation March 1, 1928
