Summary

Standing at a height of 11 feet and stretching 180 feet in length, this masonry dam holds a storage capacity of 120 acre-feet, with a surface area of 30 acres and a drainage area of 1.75 square miles. The dam, situated on the Mt Hope River Tributary, not only provides recreational opportunities but also plays a vital role in flood control and water resource management in the area.

Despite its historical significance and recreational value, Mclaughlin Pond Dam is currently assessed to be in poor condition, with a significant hazard potential. The last inspection in 2015 highlighted the need for improvements to ensure the safety and integrity of the structure. As a state-regulated dam under the jurisdiction of the Department of Energy and Environmental Protection (DEEP), ongoing maintenance, inspection, and enforcement measures are in place to address the dam's condition and mitigate potential risks associated with its operation.

Given the dam's critical role in water management and recreation, efforts are being made to address its condition and enhance its safety measures. With a designated inspection frequency of 5 years, stakeholders are working towards implementing necessary repairs and improvements to meet regulatory guidelines and ensure the long-term sustainability of Mclaughlin Pond Dam. As a focal point for water resource and climate enthusiasts, the dam serves as a reminder of the importance of maintaining infrastructure to safeguard both natural and recreational resources for future generations.

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.
