Summary

Nestled along the Northeast Branch of the river, this dam stands at a height of 22 feet and has a hydraulic height of 20 feet, providing storage of up to 1550 acre-feet of water. The dam spans 450 feet in length and covers a surface area of 67 acres, making it a significant resource for both irrigation and recreational activities.

Despite its vital role in water management and leisure, the Prince George Country Club Dam has a high hazard potential and is currently assessed to be in poor condition. The dam is under state jurisdiction and regulation by the Maryland Dam Safety agency, with regular inspections and enforcement measures in place. In the event of an emergency, the dam lacks an Emergency Action Plan (EAP) preparedness, raising concerns about its ability to meet guidelines and effectively manage risks. With its uncontrolled spillway type and moderate risk assessment, there is a pressing need for improved risk management measures to ensure the safety and longevity of this essential water resource infrastructure.

For water resource and climate enthusiasts, the Prince George Country Club Dam serves as a focal point for understanding the intersection of recreational activities, water storage, and dam safety. As the dam faces challenges in maintenance and emergency preparedness, there is an opportunity for stakeholders to collaborate on implementing sustainable solutions that address the high hazard potential and poor condition assessment. By leveraging expertise from state regulatory agencies and engaging in proactive risk management measures, the community can safeguard the dam's integrity and enhance its resilience to environmental changes, ultimately preserving this valuable water resource 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.
