Summary

Built in 1985 by Greenhorne & O'Mara, this dam serves primarily for recreation purposes, offering a serene surface area of 4.25 acres and a normal storage capacity of 30 acre-feet. With a dam height of 14 feet and a length of 450 feet, Tall Oaks Crossing provides a tranquil setting for outdoor enthusiasts to enjoy.

Managed by the Maryland Dam Safety regulatory agency, Tall Oaks Crossing has a significant hazard potential and is subject to regular inspections to ensure its structural integrity. Although its condition assessment is currently "Not Rated," the dam's risk assessment categorizes it as moderate, highlighting the need for ongoing risk management measures to mitigate any potential hazards. Despite its uncontrolled spillway type and limited drainage area of 0.18 square miles, the dam continues to be a popular destination for local residents seeking recreation and relaxation in a natural setting.

As part of the broader water resource infrastructure in Maryland, Tall Oaks Crossing plays a crucial role in providing recreational opportunities while also serving as a key component in the state's efforts to regulate and manage its water resources effectively. With its peaceful surroundings and moderate risk profile, this earth dam stands as a testament to the intersection of engineering, environmental stewardship, and public enjoyment in the realm of water resource management and climate resilience.

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.
