Stratford Bog Pond Dam dam
Stratford Bog Pond Dam
Stratford Bog Pond Dam, located in Coos County, New Hampshire, is a state-owned structure primarily used for recreational purposes. Built in 1934, this earth dam stands at a height of 15.5 feet with a length of 240 feet, creating a storage capacity of 392 acre-feet. Situated on Bog Brook, this dam also serves to control the flow of water, with a maximum discharge capacity of 1308 cubic feet per second.
Despite its important role in water management and recreation, the dam is classified as having a high hazard potential and is currently in poor condition. The last assessment in 2016 indicated a need for maintenance and improvements, highlighting the importance of regular inspections and risk management measures. With a moderate risk rating, it is crucial for the responsible state agency, NHDES DAM BUREAU, to prioritize the safety and maintenance of this vital infrastructure to ensure the protection of surrounding communities and the environment.
For water resource and climate enthusiasts, the Stratford Bog Pond Dam represents an intriguing case study of the challenges and responsibilities associated with managing aging infrastructure in the face of evolving environmental conditions. As climate change impacts become more pronounced, the need for resilient and well-maintained dams like this one will only grow. By staying informed and advocating for sustainable practices, enthusiasts can play a role in protecting our water resources and adapting to a changing climate.

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 Stratford Bog Pond Dam
Where does the data for Stratford Bog 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 High 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.
