About General Edgar Jadwin Dam
The primary purpose of General Edgar Jadwin Dam is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by USACE - Philadelphia District (federal). It impounds the Dyberry Creek near Honesdale.
The dam stands 110 feet tall and stretches 1,255 feet across, creates a reservoir covering 1 acres, has a maximum storage capacity of 47,300 acre-feet, and collects water from a drainage area of 65 square miles. Completed in 1960, the structure is well into its service life at over 50 years old.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. An emergency action plan is in place for this dam. The most recent inspection on record was 08/03/2021.
At 110 feet, this dam is taller than 98% of all dams in the United States.
