Diamond Pond dam
Diamond Pond
Diamond Pond, located in Danville, New Hampshire, is a private recreational water resource regulated by the NHDES Dam Bureau. This concrete dam, completed in 1979, stands at a height of 12 feet and has a storage capacity of 52.72 acre-feet, with a normal storage level of 24 feet. The pond covers a surface area of 13.18 acres and is fed by Colby Brook, offering a serene and picturesque setting for water and climate enthusiasts to enjoy.
The dam at Diamond Pond serves primarily for recreational purposes, with a spillway type listed as 'Uncontrolled' and a moderate hazard potential. Despite being ungraded in terms of condition assessment, the dam is inspected every 10 years, with the last inspection conducted in December 2017. The risk assessment for Diamond Pond is classified as moderate, highlighting the importance of ongoing monitoring and management measures to ensure the safety and sustainability of this valuable water resource.
With its tranquil setting, recreational opportunities, and important role in the local ecosystem, Diamond Pond is a significant water resource in Rockingham County, New Hampshire. As climate change continues to impact water availability and quality, the management and maintenance of this dam will be crucial in preserving the pond's ecological integrity and ensuring its continued enjoyment by visitors and residents alike.

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 Diamond Pond
Where does the data for Diamond Pond 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 Undetermined 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.
