Acme Pond Dam dam
Acme Pond Dam
Acme Pond Dam, located in Windham, Connecticut, has been a primary source of recreation since its completion in 1846. This earth dam, with a height of 16 feet and a length of 600 feet, holds a storage capacity of 29 acre-feet and covers a surface area of 3 acres. The dam is situated on the Whetstone Brook and is regulated by the Connecticut Department of Energy and Environmental Protection (DEEP), ensuring regular inspections and enforcement of safety measures.
Despite being marked as having a high hazard potential, Acme Pond Dam has a satisfactory condition assessment as of June 2020. The dam features an uncontrolled spillway with a width of 17 feet and outlet gates controlled by valves. In case of emergency, the dam has an Emergency Action Plan (EAP) in place, last revised in July 2018. With a moderate risk assessment rating of 3, the dam's risk management measures and inundation maps prepared signify a proactive approach to mitigating potential hazards and ensuring public safety.
For water resource and climate enthusiasts, Acme Pond Dam serves as a historical and recreational landmark in Killingly, Connecticut. Its role in providing water storage, flood control, and recreational opportunities underscores the importance of proper dam maintenance and regulatory oversight in safeguarding both the environment and the community. With a rich history dating back over a century, Acme Pond Dam stands as a testament to the resilience and ingenuity of water resource management in the region.

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 Acme Pond Dam
Where does the data for Acme 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.
