Summary
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
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
