Summary

Standing at a height of 25.7 feet with a storage capacity of 28.4 acre-feet, this earth dam plays a crucial role in mitigating potential flooding in the area. Although not regulated by the state, the dam's primary purpose is to protect the surrounding community from the impacts of extreme weather events.

Managed by private owners, Compton Village Lake Dam has not been rated for its condition assessment, and its hazard potential remains undetermined. Despite lacking a formal inspection frequency and emergency action plan, the dam continues to serve its intended function effectively. With a structural height matching its hydraulic height, this dam stands as a testament to the importance of proactive flood risk reduction measures in the face of a changing climate.

As water resource and climate enthusiasts, the Compton Village Lake Dam presents an intriguing case study in private ownership and flood risk management. With its location in the Baltimore District and proximity to the Bull Run tributary, this structure underscores the need for sustainable infrastructure solutions that balance ecological considerations with community safety. As we navigate the challenges of a warming world, dams like these play a critical role in safeguarding our water resources and adapting to the impacts of climate change.

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.
