Powwow Pond Dam dam
Powwow Pond Dam
Powwow Pond Dam, also known as Trickling Falls Dam, is a state-owned structure located in East Kingston, New Hampshire. Completed in 1940, this recreational dam along the Powwow River stands at 12 feet high and spans 250 feet in length. With a storage capacity of 3,761 acre-feet and a surface area of 353 acres, it serves as a popular destination for outdoor enthusiasts seeking water-based activities.
Managed by the New Hampshire Department of Environmental Services Dam Bureau, Powwow Pond Dam is classified as an earth dam with a significant hazard potential and fair condition assessment. Despite its age, the dam has undergone inspections every 4 years, with the last assessment conducted in September 2019. While the risk assessment for this structure is moderate, there are currently no emergency action plans in place, highlighting the need for continued monitoring and maintenance to ensure the safety of surrounding communities in the event of a dam failure.
As a vital component of the local ecosystem and recreational landscape, Powwow Pond Dam plays a crucial role in water resource management in Rockingham County, New Hampshire. Its presence not only provides opportunities for outdoor recreation but also underscores the importance of sustainable dam infrastructure practices to mitigate potential risks and safeguard the surrounding environment from the impacts of climate change.

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 Powwow Pond Dam
Where does the data for Powwow 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.
