Summary

This private dam, with a hazard potential deemed "Undetermined" and a condition assessment of "Not Rated," is a significant structure in the region. Despite not being regulated by the state, the dam serves a crucial purpose in water resource management and climate resilience efforts.

Managed by the Baltimore District of the US Army Corps of Engineers, Ft Ap Hill Dam's exact year of completion and primary purpose remain unknown. With a structural height matching its hydraulic height, this dam spans 325 feet in length and covers a surface area of 3 acres. Although its inspection frequency is currently set at 0, the dam's emergency action plan status, risk assessment, and management measures are also unspecified.

Water resource and climate enthusiasts intrigued by the intricacies of dam infrastructure will find Ft Ap Hill Dam a fascinating case study. Its impressive stature, location in Caroline County, and association with the US Army Corps of Engineers present a unique blend of mystery and importance in the realm of water management and environmental stewardship.

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.
