Summary
This private dam, standing at a height of 25 feet, has a storage capacity of 27 acre-feet and covers a surface area of 2 acres. While primarily used for recreational activities, it also contributes to the overall drainage area of 75 square miles, providing essential support to the local ecosystem.
Managed by a private owner, Harring Lake Dam poses a low hazard potential and has not been rated for its condition assessment. Despite lacking state regulation and inspection, this earth dam with a buttress core continues to play a crucial role in water resource management along the TR-Turkey Creek. Although the dam has not been modified in recent years, its historical significance and contribution to the surrounding community make it a noteworthy structure for water resource and climate enthusiasts to explore.
While Harring Lake Dam does not fall under the jurisdiction of state or federal agencies, it remains a valuable asset for the Frederickburg area, enhancing fire protection capabilities and supporting recreational activities. With its modest storage capacity and low hazard potential, the dam stands as a testament to sustainable water management practices, showcasing the importance of private initiatives in maintaining water resources. As enthusiasts delve into the details of this dam, they will uncover a rich history and a continued commitment to preserving the natural environment for future generations.

Dam Data Reference
Condition Assessment
SatisfactoryNo 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
HighDams 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.
