Summary

3, located on Stream Crossing Road in Baltimore, Maryland, is a private earth dam built in 1995 for flood risk reduction on the Jones Falls-TR-Moores Branch river system. The dam stands at a height of 33.6 feet and has a storage capacity of 58 acre-feet, with a normal storage level of 15.68 acre-feet. Despite its low hazard potential, the dam is currently assessed as being in poor condition as of May 2017.

The dam has a surface area of 1.8 acres and serves a drainage area of 0.23 square miles, with a maximum discharge capacity of 163 cubic feet per second. It features an uncontrolled spillway with a width of 4 feet. The structure is under the jurisdiction of the Maryland Dam Safety regulatory agency and undergoes regular inspections every five years. With its moderate risk assessment of 3, there may be a need for improved risk management measures to ensure the safety and functionality of the dam.

Enthusiasts interested in water resources and climate change will find Greenspring East Swm Pond No. 3 to be an intriguing case study of a privately owned dam designed for flood risk reduction. The data reveals the importance of maintaining infrastructure like dams to mitigate hazards, protect communities, and ensure sustainable water management in the face of a changing climate. The dam's location within the Baltimore District highlights the interconnectedness of water resources and the need for comprehensive regulatory oversight to address potential risks and vulnerabilities.

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.
