Summary
Owned privately, this structure was completed in 1988 and stands at a height of 26 feet with a length of 700 feet. With a storage capacity of 20 acre-feet and a surface area of 1.1 acres, the pond plays a crucial role in managing water levels and providing recreational opportunities for the community.
Managed by the Maryland Dam Safety agency, Medford Quarry Wash Pond undergoes regular inspections to ensure its fair condition and significant hazard potential are addressed. The dam's spillway, an uncontrolled type with a width of 3 feet, helps regulate the maximum discharge of 34 cubic feet per second. Despite being modified structurally in 2009, the pond continues to meet the moderate risk assessment criteria, highlighting the importance of ongoing monitoring and maintenance to ensure its effectiveness in flood risk reduction and recreational use.
With a history of design by Frederick Ward Associates and intake by Stearns & Wheeler, Medford Quarry Wash Pond stands as a cornerstone in water management and climate resilience efforts in Carroll County, Maryland. As water resource and climate enthusiasts, understanding the critical role of structures like Medford Quarry Wash Pond in balancing flood control and recreational needs underscores the importance of sustainable water management practices for the benefit of both the environment and the community.

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.
