Welcome to Prompton & General Edgar Jadwin Dams

The Prompton Dam was constructed in 1960 to reduce flood risks primarily for the communities of Prompton, Pennsylvania, Hawley, Pennsylvania and Honesdale, Pennsylvania. The 1230-foot long and 147-foot high earthen dam was built in response to severe floods on the Lackawaxen River in 1936, 1942 and 1955.

The General Edgar Jadwin Dam was constructed by the U.S. Army Corps of Engineers in 1960 and has prevented more than $34 million in flood damages.

Jadwin Dam, located approximately three miles above the confluence of Dyberry Creek with Lackawaxen River, in Honesdale, Pa, experienced high water conditions following Hurricane Ivan in 2004.

The Prompton and General Edgar Jadwin Reservoirs are part of an integrated reservoir flood control system located in northeast Pennsylvania. The two reservoirs work in conjunction to provide flood control protection in varying degrees, to the Bouroughs of Prompton, Honesdale and Hawley, and to smaller communities along the Lackawaxen River. 

Prompton Dam is located on the West Branch Lackawaxen River, a tributary of the Lackawaxen River, approximately 4.7 miles upstream of Honesdale, PA and a half mile upstream of the Village of Prompton, PA. 

Completed in July 1960, the dam is a 1,230-foot long, 140-foot high earthfilled embankment with an unregulated outlet works. The 8-foot wide conduit restricts the outflow of water from the reservoir through the dam and therefore "controls" the water released downstream. 

The Jadwin Dam is a dry dam located on the Dyberry Creek, a tributary of the Lackawaxen River, approximately 2.9 miles upstream of Honesdale, PA.

 Completed in September 1959, the dam is a 1,255-foot long, 109-foot high earthfilled embankment. 

The reservoir at Prompton Dam, known as Prompton Lake, offers recreational opportunities such as boating, fishing, and wildlife viewing. Additionally, the project resources offer limited picnicking, hiking trails, and an 18 hole disc golf course.
