Located in Wayne, Pennsylvania, Prompton Dam, also known as Prompton Lake, is a federal-owned structure managed by the US Army Corps of Engineers. Built in 1961, this earth-type dam stands at a structural height of 140 feet with a hydraulic height of 127 feet, creating a reservoir with a maximum storage capacity of 72,800 acre-feet. The primary purpose of Prompton Dam is flood risk reduction, with additional benefits for recreation.

Despite being classified as a high hazard potential dam, extensive risk management measures have been implemented to enhance its safety. In 2012, modifications were made to increase the spillway's flow capacity and raise the dam's height, reducing the risk of overtopping during extreme flood events. Regular inspections, monitoring, and emergency preparedness protocols are in place to ensure the dam's structural integrity and mitigate potential risks to downstream communities such as Honesdale and Hawley. These efforts demonstrate the commitment of the US Army Corps of Engineers to safeguarding water resources and protecting against the impacts of climate-related events.
