Summary

This private hydroelectric dam stands at a height of 15 feet, with a hydraulic height of 18 feet and a structural height of 18 feet. The pond covers an impressive surface area of 83 acres and has a maximum storage capacity of 625 acre-feet, making it a significant feature in the local landscape.

Not only does Locustville Pond serve a primary purpose of hydroelectric power generation, but it also provides opportunities for recreation in the area. With a normal storage capacity of 530 acre-feet and a maximum discharge of 1497 cubic feet per second, the pond plays a crucial role in regulating water flow in Brushy Brook. However, its high hazard potential underscores the importance of regular inspections and maintenance to ensure the safety and integrity of the structure.

Despite its high hazard potential, Locustville Pond's condition assessment remains "Not Rated," emphasizing the need for ongoing risk management measures and emergency preparedness. With its picturesque surroundings and dual functions of hydroelectric power generation and recreational use, the pond stands as a testament to the intersection of water resource management and climate resilience in the region. As climate enthusiasts and water resource advocates, the preservation and sustainable management of Locustville Pond serve as a reminder of the delicate balance between human development and environmental stewardship.

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.
