Summary

Constructed in 1930, this gravity dam stands at a height of 15 feet and spans 300 feet in length. With a storage capacity of 75 acre-feet and a surface area of 6 acres, the dam plays a crucial role in maintaining the ecological balance of the tributary of Seven Mile River.

Managed by the Department of Conservation and Recreation, Woodman Pond Dam is regulated and inspected by the state authorities to ensure its structural integrity and safety. Despite being classified as having a low hazard potential, the dam is rated as being in fair condition. With an inspection frequency of 10 years, the dam's risk assessment is moderate, highlighting the need for continued monitoring and maintenance to mitigate any potential risks.

Overall, Woodman Pond Dam stands as a testament to the importance of water resource management in promoting biodiversity and supporting recreational activities. As a designated fish and wildlife pond, this structure not only provides environmental benefits but also offers a serene setting for visitors to enjoy nature. Through ongoing oversight and risk management measures, Woodman Pond Dam continues to fulfill its role in safeguarding the surrounding ecosystem and enhancing the community's access to outdoor recreation opportunities.

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. 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

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, 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.
