Summary
Completed in 1940, this private-owned Earth dam stands at a height of 10 feet and spans 325 feet in length, holding a maximum storage capacity of 192 acre-feet. With a normal storage capacity of 110 acre-feet, the dam plays a crucial role in managing the water resources of the region.
Managed by the NHDES Dam Bureau, Mud Pond Dam is regulated, inspected, and enforced by the state of New Hampshire to ensure its structural integrity and safety. With a low hazard potential and fair condition assessment, the dam poses a moderate risk (level 3) and undergoes inspections every 6 years. Despite its uncontrolled spillway type and limited spillway width, the dam continues to provide reliable water storage and management for the Mud Pond Brook and surrounding areas.
Water resource and climate enthusiasts can appreciate Mud Pond Dam for its role in maintaining a sustainable water supply system in Coos County, New Hampshire. As a key infrastructure for water management, this dam stands as a testament to the careful balance between human resource needs and environmental stewardship in the region. Its historical significance and ongoing maintenance efforts highlight the importance of responsible dam ownership and regulation in ensuring the resilience of water resources in the face of changing climate conditions.

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.
