Summary
Built in 1950, this earth dam spans 250 feet in length and reaches a height of 10 feet, with a storage capacity of 174 acre-feet. Despite its modest size, Moose Falls Dam plays a significant role in the local ecosystem, serving as a key element in managing water resources and maintaining the surrounding habitat.
Managed by the New Hampshire Department of Environmental Services Dam Bureau, Moose Falls Dam is subject to state regulation, permitting, inspection, and enforcement, ensuring its structural integrity and compliance with safety standards. However, recent assessments have raised concerns about the dam's condition, with a poor rating indicating the need for maintenance and potential upgrades to mitigate its significant hazard potential. With a moderate risk assessment in place, stakeholders must prioritize risk management measures to safeguard the dam and the community it serves.
As water resource and climate enthusiasts monitor Moose Falls Dam's status, its role in environmental conservation and water management remains vital. The dam's location within the Coos County landscape underscores its importance in balancing water supply, flood control, and habitat preservation along the Connecticut River. By addressing maintenance needs and implementing risk mitigation strategies, Moose Falls Dam can continue to fulfill its mandate while adapting to evolving climate challenges and ensuring long-term resilience for the region.

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.
