Dana Pond Dam dam
Dana Pond Dam
Dana Pond Dam, located in Dalton, New Hampshire, is a privately owned structure designed by USDA NRCS with a primary purpose of recreation. Built in 1975, this earth dam stands at a height of 20 feet and spans 500 feet in length, providing a storage capacity of 77 acre-feet. The dam regulates TR JOHNS BROOK and has a drainage area of 0.77 square miles.
Despite being classified as having a significant hazard potential, Dana Pond Dam is in satisfactory condition according to a 2012 assessment. Regular inspections are conducted, with the last inspection taking place in June 2019. The dam is state-regulated by NHDES DAM BUREAU, ensuring that it meets all safety and regulatory standards. With a moderate risk assessment rating, the dam poses a manageable level of risk to the surrounding area.
Water resource and climate enthusiasts interested in Dana Pond Dam will find it to be a valuable recreational asset in Coos County, New Hampshire. The dam offers opportunities for outdoor activities in a picturesque setting while also serving a crucial function in regulating water flow. With its manageable risk level and regular inspections, Dana Pond Dam is a well-maintained structure that contributes to the overall 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 Dana Pond Dam
Where does the data for Dana 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.
