Blue Marsh Lake, located in Berks County, Pennsylvania, was constructed in the early 1970s for flood control, water supply, and recreational purposes. The lake is part of the Tulpehocken Creek Watershed and is fed by the Tulpehocken Creek and several smaller tributaries. The hydrology of the lake is managed by the U.S. Army Corps of Engineers and includes a system of dams, reservoirs, and pumping stations to maintain water levels.
Surface flow providers include the Tulpehocken Creek, Spring Creek, Dry Brooks, and Blue Marsh Creek, while snowpack can contribute to water levels during the winter months. The lake provides water for local agriculture and is also used for recreational activities such as boating, fishing, biking, and hiking. The area surrounding the lake is managed by the U.S. Army Corps of Engineers and offers various amenities such as campgrounds, picnic areas, and a beach.
