Prompton State Park (adjacent to the Prompton Dam owned and operated by the U.S. Army Corps of Engineers Philadelphia District) includes 26 miles of hiking trails and an 18-hole Frisbee golf course. Prompton Dam has prevented more than $27 million in damages since its construction in 1960. It was built in response to severe floods on the Lackawaxen River in 1936, 1942 and 1955.
