Mountain Pond Dam dam
Mountain Pond Dam
Mountain Pond Dam, located in New Ipswich, New Hampshire, is a privately owned structure regulated by the NHDES Dam Bureau. It serves primarily for fire protection and as a stock or small fish pond along the Millers River. The dam, with a height of 13 feet and a length of 175 feet, has a storage capacity of 154 acre-feet and a surface area of 20 acres. It has a low hazard potential and is currently in fair condition, as assessed in November 2017.
Despite its relatively small size, Mountain Pond Dam plays a crucial role in water resource management in the region, providing essential storage and mitigation against potential flooding events. The dam, constructed with earth and stone materials, features an uncontrolled spillway with a width of 8 feet. It is inspected every 6 years, with the last assessment conducted in November 2017, showcasing its commitment to safety and regulatory compliance. Additionally, the dam has a moderate risk rating of 3, highlighting the importance of ongoing risk management measures.
As a significant structure in the New England District, Mountain Pond Dam underscores the importance of private ownership in maintaining water resource infrastructure. Its association with fire protection and fisheries highlights the diverse roles dams play in supporting both human needs and environmental conservation efforts. With a focus on safety, efficiency, and regulatory compliance, Mountain Pond Dam stands as a testament to responsible water resource management in the face of changing climate conditions.

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 Mountain Pond Dam
Where does the data for Mountain 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.
