Prompton Dam

Welcome to Prompton & General Edgar Jadwin Dams

Prompton Dam
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.
Bald Eagle at Prompton State Park
Bald eagles require habitat with large water and forest resources to provide them with fish for food and trees for building their nests. Exclusive to North America, bald eagles can be found at all of the Northern Area Dam & Reservoir Projects.
Fall Foliage Along West Branch Lackawaxen
The West Branch Lackawaxen River forms the headwaters and main channel of the Prompton Lake reservoir. Lackawaxen is a Lenape word meaning “swift waters”. The Lenape people are the original inhabitants of Delaware, New Jersey, Eastern Pennsylvania, and Southern New York.

Summer Bunny
The Eastern Cottontail Rabbit is the most popular game animal in Pennsylvania and can be found throughout suburban and rural landscapes. The U.S. Army Corps of Engineers projects conduct environmental stewardship initiatives that help provide habitat resources for these furry residents and a variety of other species.
Jadwin Dam Safety Modification Project
The U.S. Army Corps of Engineers and its contractor constructed a Dam Safety Modification project at Jadwin Dam in Wayne County, PA. Work involved the installation of a geosynthetic liner system on part of the upstream slope and crest of the dam.
Waterfall at Prompton State Park
Waterfalls occur where water flows over a vertical drop or a series of steep drops along the course of a stream or river. These features can be found while hiking the 26 miles of hiking trails developed by Pennsylvania DCNR’s Prompton State Park.
General Edgar Jadwin Dam
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 & Hurricane Ivan 2004
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.
