General Edgar Jadwin Reservoir, located in Pennsylvania, was initially constructed in 1940 to help control floods in the Susquehanna River Basin. The reservoir spans over 4,000 acres and can hold up to 20 billion gallons of water. The hydrology of the reservoir is primarily fed by the Lackawanna River, which flows into the Susquehanna River. The reservoir also receives water from surface flow and snowpack providers such as the Tunkhannock Creek and Bear Creek. The reservoir serves as a source of water supply for several municipalities and facilitates irrigation for agricultural purposes. Additionally, the reservoir provides recreational opportunities like fishing and boating. Its surrounding areas also offer opportunities for hiking and camping.
