Blue Marsh

While the main purpose of Blue Marsh was to provide flood control to part of the Schuylkill River Valley, over the years the lake has become a recreational hotspot. With over 36 miles of trails, 6200 acres of land, 1148 acres of water, picnic areas, a small beach and boat launches the lake can accommodate all kinds of outdoor enthusiasts. The dam is an earthfill dam that that is 1,775 feet long, 98 feet high and can hold upwards of 16.28 billion gallons of water. During the summer months, the water level is maintained at 290 feet above sea level. In the winter the lake is drawn down five feet to provide for additional flood water storage.
