About Shenipsit Flood Control Site #6 Dam
The primary purpose of Shenipsit Flood Control Site #6 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 Connecticut Deep (state). It impounds the Edson Brook Trib near Stafford Springs.
The dam stands 29 feet tall and stretches 390 feet across, creates a reservoir covering 29 acres, has a maximum storage capacity of 520 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1961, 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. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 04/25/2023.
