General Edgar Jadwin Dam & Reservoir

General Edgar Jadwin Dam and Reservoir. . , The General Edgar Jadwin Dam project is part of an integrated reservoir flood risk management system with the Prompton Lake project. Both are managed by the U.S. Army Corps of Engineers' Philadelphia District., Jadwin Dam is located on Dyberry Creek, approximately 3 miles north from its confluence with the Lackawaxen River and from the Borough of Honesdale, Wayne County, Pennsylvania., Jadwin is a dry dam that maintains no pool during normal operation. The total capacity of the reservoir is reserved for flood control, which has always been the sole authorized purpose for this project. Its prime function is to temporarily hold back waters that exceed the flow capacity of its outlet works, and then release them gradually so as not to cause bank overflow., The dam can provide 24,500 acre-feet of storage to the spillway crest - which is equivalent to 7.1 inches of runoff from the drainage area above the dam - 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 Dyberry Creek started in June 1957, and the dam was dedicated in June 1959., As of September 2020, Jadwin Dam has prevented an estimated $36.6 million in flood damages since its construction. Together with Prompton Dam, which began operating the same year (1960), they represent a combined $65.7 million in cumulative damages prevented within the Lackawaxen River Sub-basin and the Delaware River Basin., LIEUTENANT GENERAL EDGAR JADWIN , CHIEF OF ENGINEERS (1926-1929). , Edgar B.
