$4.9 million contract for geosynthetic liner system installation nears completion

The U.S. Army Corps of Engineers’ Philadelphia, Pa. district and its contractor, Mohawk Valley Materials of Marcy, N.Y., will soon begin construction on improvements at the General Edgar Jadwin Dam in Wayne County, Pa. The contractor mobilized to the site in 2022 and work is ongoing currently and estimated for completion in spring of 2023. 

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.

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.
