Summary
Built in 1888, this earth dam stands at a height of 15 feet and has a hydraulic height of 13 feet. With a storage capacity of 310 acre-feet and a surface area of 29 acres, the dam plays a crucial role in providing recreation opportunities and supporting the local ecosystem.
Despite its historical significance and importance for the community, Carpenter Pond Dam is facing challenges in terms of its condition assessment and hazard potential. The dam has been rated as having a poor condition and a significant hazard potential, highlighting the need for regular inspections and maintenance to ensure its safety and effectiveness. Additionally, the risk assessment for the dam is moderate, indicating the importance of implementing risk management measures to mitigate potential threats.
Managed by the Department of Conservation and Recreation, Carpenter Pond Dam is subject to state regulations and inspections to ensure compliance with safety standards. As a key component of the local water resource infrastructure, it is essential for water resource and climate enthusiasts to stay informed about the dam's status and the efforts being made to address its maintenance and safety concerns.

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.
