The U.S. Army Corps of Engineers (USACE) will present at the Wayne County Commissioners working session on March 10, to kick off a process to revise the 1959 General Edgar Jadwin Dam Master Plan (originally titled Dyberry Reservoir). The working session will begin at 10:30 a.m. at the Commissioners Meeting Room located on the 3rd floor of the Court House Annex building in Honesdale, Pennsylvania.

Master Plan Overview

The master plan is defined as the strategic land use management document that guides the comprehensive management and development of all recreational, natural, and cultural resources throughout the life of the water resource development project. It defines "how" USACE will manage the resources for public use and conservation.

The current Jadwin Dam Master Plan, last approved in 1959, needs revision to address changes in regional land use, population, outdoor recreation trends, and the USACE management policy.

Key topics to be discussed in the revised master plan include updated land use classifications, new natural and recreational resource management objectives, recreation facility needs, and special issues such as invasive species management and threatened and endangered species habitat. Current land classification at Jadwin Dam can be found on the map above.

The master plan revision will not address the technical and operational aspects related to the flood risk management mission of the project.

Initial Comment Period

An initial 30-day comment period will begin March 10 and end April 9; however, there will be future comment periods associated with the draft document in June 2026. The public can send comments, suggestions, and concerns during this time. Comments must be submitted in writing at the Commissioners meeting or digitally via the comment form on the master plan revision webpage: https://www.nap.usace.army.mil/Missions/Civil-Works/Prompton-Jadwin-Dam/Jadwin-Dam-Master-Plan/.

About Jadwin Dam

Jadwin Dam was constructed by the USACE in 1959. The dam is a 1,255-foot-long and 109-foot-high zoned earth and rockfill embankment. The project was authorized for construction by the Flood Control Act of 1946 (PL 79-526) and modified by the Flood Control Act of 1954 (PL 83-780).

Jadwin is a dry dam with no normal long-term storage allocated and has no authorized purposes other than flood control. Jadwin can provide 24,189 acre-feet of storage to the spillway crest and a total of 35,321 acre-feet of storage at maximum spillway design flood pool. The dam is located on the Dyberry Creek, a tributary of the Lackawaxen River, approximately two miles upstream of the Borough of Honesdale, Pennsylvania.  Jadwin Dam and Prompton Dam and Reservoir are part of an integrated reservoir flood control system. The two reservoirs work in conjunction to provide flood control protection in varying degrees, to the boroughs of Prompton, Honesdale and Hawley, and to smaller communities along the Lackawaxen River. Since its completion in 1959, the dam has prevented more than $50 million in flood damage through fiscal year 2024.
