Summary

With a height of 37 feet and a length of 591 feet, this earth dam serves to protect the surrounding area from potential flooding events. The dam has a maximum storage capacity of 708 acre-feet, with a normal storage level of 340 acre-feet, covering a surface area of 40 acres.

Managed by the local government and regulated by the Department of Conservation and Recreation, Potomac Creek Dam #2 has a high hazard potential but is currently assessed as satisfactory in condition. The dam was last inspected in October 2019 and meets state regulatory standards for inspection, permitting, and enforcement. While primarily serving the purpose of flood risk reduction, the dam also provides recreational opportunities for the community.

Despite its critical role in protecting the area from flooding, Potomac Creek Dam #2 does not have a designated emergency action plan (EAP) and lacks updated inundation maps and risk assessment measures. With the potential for high hazard situations, it is essential for the stakeholders to prioritize the development of an EAP and ensure that risk management measures are in place to address any potential emergencies effectively.

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.
