The Deep Creek Project was begun in 1922 by the Youghiogheny Hydro-Electric Corporation and was completed in 1925. Deep Creek Lake is the largest man-made lake in Maryland. At full pool, Deep Creek Lake has 65 miles of shoreline and sits at 2462 feet above sea level. In 2000, the State of Maryland purchased the land underlying Deep Creek Lake, buffer zone properties, and certain other parcels from General Public Utility, Inc.
