Beaupres Pond Dam dam
Beaupres Pond Dam
Beaupres Pond Dam, located in Pomfret, Connecticut, is a private-owned structure built in 1952 primarily for recreational purposes. The dam, standing at a height of 12 feet and stretching 385 feet in length, holds a maximum storage capacity of 66 acre-feet and covers an 8-acre surface area. The Lyon Brook river flows through this area, contributing to a drainage area of 0.4 square miles.
With a spillway width of 16 feet and a maximum discharge capacity of 130 cubic feet per second, Beaupres Pond Dam poses a high hazard potential, although its condition assessment as of April 2018 was deemed as satisfactory. The dam is state-regulated by the Department of Energy and Environmental Protection (DEEP) in Connecticut, with regular inspections conducted every two years. Despite its moderate risk assessment, the dam has not been modified in recent years, and emergency action plans have not been updated since 1988.
For water resource and climate enthusiasts, Beaupres Pond Dam presents an interesting case study in private dam ownership and management for recreational purposes. Its location in Windham County, Connecticut, adds to the charm of the area, while the structural design and hydraulic features of the dam offer insights into the intersection of water management, safety regulations, and environmental stewardship in the region. Understanding the dynamics of this dam can provide valuable lessons for sustainable water resource management and climate resilience efforts in similar settings.
Dam data reference
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 Beaupres Pond Dam
Where does the data for Beaupres Pond Dam 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 High 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.
