Summary

Constructed in 1988 by The Reimer Group, this 18.5-foot earth dam serves as a flood risk reduction measure along the Dorsey Run Trib. With a storage capacity of 11.6 acre-feet and a surface area of 0.9 acres, the pond plays a crucial role in managing stormwater and mitigating potential flooding in the area.

The dam's spillway, with a width of 66 feet, is designed for uncontrolled release during high water events, with a maximum discharge capacity of 884 cubic feet per second. Despite being classified as having a significant hazard potential, the pond's condition assessment is currently rated as fair. Regular inspections are conducted to ensure the dam's integrity and functionality, with the last assessment taking place in December 2021. With its strategic location and vital role in flood risk reduction, Gateway Village Pond stands as a resilient water resource in Howard County, Maryland, safeguarding the surrounding community from potential water-related hazards.

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.
