Summary
Completed in 1985, this Earth dam stands at a height of 46.9 feet and serves the primary purpose of flood risk reduction along the Weems Creek. With a storage capacity of 140 acre-feet and a normal storage level of 25.7 acre-feet, this significant structure plays a crucial role in mitigating potential flooding in the area.
Although the condition of the dam is currently rated as "Not Rated," it undergoes inspections every three years to ensure its structural integrity and effectiveness in flood control. The hazard potential is classified as significant, highlighting the importance of regular monitoring and maintenance. In 2002, the dam was modified for seismic considerations, further enhancing its resilience to potential risks. Despite not being owned or funded by federal agencies, this state-regulated structure plays a vital role in the local water resource management and climate resilience efforts in Maryland.
For water resource and climate enthusiasts, Jennifer Road Swm Route 50 and Route 2 is a noteworthy example of a state-managed flood risk reduction infrastructure in Maryland. Its location along the Weems Creek, its significant hazard potential, and its role in mitigating potential flooding make it a key component of the region's water management system. As efforts continue to assess and improve the structure's condition and resilience, it serves as a symbol of the ongoing commitment to safeguarding communities against the impacts of climate change and extreme weather events.

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.
