WAYNE COUNTY, PA —The U.S. Army Corps of Engineers’ Philadelphia District and its contractor, Mohawk Valley Materials of Marcy, NY, will soon begin construction on improvements at the General Edgar Jadwin Dam in Wayne County, Pennsylvania.
Jadwin Dam is located on Dyberry Creek north of the borough of Honesdale in Wayne County. It’s a dry dam with no permanent pool of water behind it. A multi-year risk assessment recommended making improvements to the upstream embankment of the dam to reduce risk. The $4.9 million contract will include the installation of a geosynthetic liner system on part of the upstream slope and crest of the dam.
The contractor plans to mobilize in July 2022. Materials will be trucked to the site via both the downstream road (Dam Road) and the upstream road off Miller Drive (Route 4006). Vehicle and pedestrian access will be limited in/around the project as well as along some reaches of the Dyberry Creek upstream and downstream of the dam (see map). These restrictions will be posted with signage.
About Jadwin Dam
Jadwin is a dry dam that maintains no pool during normal operation. The dam can provide 24,500 acre-feet of storage to the spillway crest and a total of 47,300 acre-feet of storage at maximum pool. The dam controls 64.5 square miles of the Dyberry Creek watershed in Wayne County. Construction began in May 1957, diversion of the Dyberry Creek started in June 1957 and the dam was dedicated in June 1959. Jadwin Dam has prevented approximately $40 million in flood damages since its construction.
