Hattertown Pond Dam dam
Hattertown Pond Dam
Hattertown Pond Dam, located in Huntington, Connecticut, was completed in 1840 and serves primarily for recreational purposes. The earth dam stands at a height of 11 feet and has a length of 95 feet, creating a storage capacity of 90 acre-feet. Situated on the Lewis Brook, the dam covers an area of 18 acres and has a drainage area of 1.38 square miles. Despite being privately owned, the dam is regulated by the Connecticut Department of Energy and Environmental Protection (DEEP) and undergoes regular inspections to ensure its safety.
With a significant hazard potential, Hattertown Pond Dam has not been rated for its condition assessment. The Emergency Action Plan (EAP) for the dam was last revised in 1993, and there is no current information available on its compliance with guidelines or the preparation of inundation maps. The dam has a spillway width of 19 feet and a maximum discharge capacity of 121 cubic feet per second. While the dam does not have any associated locks, it remains a focal point for recreation in the area, offering opportunities for boating and fishing on the pond created by its construction.
As a historic structure with ties to the local community, Hattertown Pond Dam represents a balance between water resource management and recreational enjoyment. Its presence on the Lewis Brook not only provides a scenic backdrop for outdoor activities but also underscores the importance of maintaining and monitoring dam infrastructure for the safety of surrounding areas. The dam's significance lies not only in its functional purpose but also in its role as a landmark that contributes to the cultural and environmental landscape of Fairfield County, Connecticut.
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 Hattertown Pond Dam
Where does the data for Hattertown 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 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.
