Perkins Pond Dam dam
Perkins Pond Dam
Perkins Pond Dam, located in Troy, New Hampshire, serves as a vital structure for local recreation purposes. Built in 1935, this earth dam stands at a height of 7 feet and spans 150 feet in length, holding a storage capacity of 181 acre-feet. The dam overlooks the Perkins Pond, making it a scenic spot for outdoor enthusiasts to enjoy water activities in the area.
Managed by the NHDES DAM BUREAU, Perkins Pond Dam is regulated and inspected by the state, ensuring its safety and compliance with standards. With a low hazard potential and fair condition assessment as of 2011, the dam continues to play a crucial role in maintaining the flood control and water supply for the region. Although the spillway is uncontrolled, the dam's design and construction reflect a moderate risk level, highlighting the importance of ongoing risk management measures.
Despite its age, Perkins Pond Dam remains a key structure in Cheshire County, New Hampshire, offering a peaceful retreat for locals and visitors alike. With its moderate risk assessment and state-regulated status, the dam stands as a testament to effective water resource management and climate resilience practices in the region. As climate enthusiasts and water resource advocates, monitoring and supporting the upkeep of structures like Perkins Pond Dam are essential to promoting sustainable water management and safeguarding our natural resources for future generations.
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 Perkins Pond Dam
Where does the data for Perkins 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 Low 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.
