Stinson Lake Dam dam
Stinson Lake Dam
Stinson Lake Dam, located in Rumney, New Hampshire, is a state-owned structure with a primary purpose of recreation. Built in 1955, this earth-type dam stands at 7.75 feet tall and stretches 158 feet in length, creating a reservoir with a capacity of 1930 acre-feet. The dam is regulated by the NHDES Dam Bureau and undergoes regular state inspections, with a low hazard potential and a satisfactory condition assessment.
The dam, situated on Stinson Brook, serves as a vital resource for the local community, offering opportunities for recreational activities such as fishing, boating, and wildlife watching. With a surface area of 346 acres and a drainage area of 8 square miles, the dam contributes to the natural landscape and biodiversity of the region. Despite its moderate risk assessment, the dam's risk management measures ensure the safety and security of the surrounding area in case of emergencies.
Overall, Stinson Lake Dam is a key infrastructure that not only provides recreational benefits but also plays a crucial role in water resource management and climate resilience in Grafton County, New Hampshire. Its impressive history, design, and regulatory oversight make it a noteworthy site for water resource and climate enthusiasts to explore and appreciate.
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 Stinson Lake Dam
Where does the data for Stinson Lake 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.
