Eddy Pray Reservoir dam
Eddy Pray Reservoir
Eddy Pray Reservoir, located in Windham County, Connecticut, is a private water resource with a primary purpose of recreation. Completed in 1900, this earth dam structure stands at a height of 10 feet and has a length of 1500 feet, providing a storage capacity of 109 acre-feet and covering a surface area of 34 acres. The reservoir is situated on Whetstone Brook and is under state jurisdiction and regulation by the Connecticut Department of Energy and Environmental Protection (DEEP).
With its significant hazard potential and condition not yet rated, Eddy Pray Reservoir is a notable feature in the region's water resource management. The dam has a spillway width of 1 foot and a maximum discharge capacity of 10 cubic feet per second, ensuring the safety of its surrounding areas in case of emergencies. Despite the last inspection dating back to 2010, the reservoir is subject to regular maintenance and oversight to ensure its structural integrity and operational efficiency for the benefit of recreational enthusiasts and climate-conscious individuals alike.
As a key component of the water infrastructure in Killingly, Connecticut, Eddy Pray Reservoir plays a crucial role in providing recreational opportunities while also contributing to the overall water management efforts in the region. With its rich history dating back over a century, this reservoir serves as a reminder of the importance of sustainable water resource development and climate resilience strategies in the face of changing environmental conditions.

Condition Assessment
- Satisfactory
- No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
- Fair
- No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
- Poor
- A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
- Unsatisfactory
- A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
- Not Rated
- The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Hazard Potential Classification
- High
- Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
- Significant
- Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
- Low
- Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
- Undetermined
- Dams for which a downstream hazard potential has not been designated or is not provided.

About Eddy Pray Reservoir
Where does the data for Eddy Pray Reservoir come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Significant hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card above for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.
