Summary

This local government-owned dam, primarily designed for recreation, is an earth-type structure with a height of 7 feet and a length of 450 feet. With a storage capacity of 15 acre-feet and a significant hazard potential, Ledgewood Pond Dam plays a crucial role in managing water resources in the region.

Despite its importance, the dam's condition assessment reveals a poor rating, emphasizing the urgent need for maintenance and repair. The last inspection in March 2022 highlighted the significance of addressing the dam's structural integrity to ensure public safety and prevent potential hazards. With a history of modification and a history dating back to completion, Ledgewood Pond Dam remains a key feature in the local landscape, calling for proactive measures to enhance its operational efficiency and safety protocols.

As climate change intensifies and water resource management becomes increasingly critical, Ledgewood Pond Dam serves as a focal point for conservation efforts and infrastructure resilience. With state regulatory oversight and regular inspections in place, the dam's role in flood control and recreational activities underscores the need for ongoing monitoring and maintenance to uphold its functionality and safeguard the surrounding community.

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.
