Summary
This earth dam stands at a height of 113.8 feet and serves the primary purpose of flood risk reduction along the Dry River. With a storage capacity of 5,780 acre-feet and a drainage area of 18.7 square miles, this dam plays a crucial role in protecting the surrounding community from potential inundation during heavy rainfall events.
Managed by the Department of Conservation and Recreation, Lower North River # 82 has been deemed to have a high hazard potential but is currently in satisfactory condition as of the last inspection in November 2020. The dam's emergency action plan has been prepared and meets guidelines, ensuring that appropriate measures are in place in case of a disaster. With a history dating back to its completion date, this dam continues to be a key component in safeguarding the region against flooding and maintaining water resource sustainability in the area.
Located within the Baltimore District, Lower North River # 82 stands as a testament to the importance of proper dam infrastructure in mitigating flood risks and protecting vulnerable communities. As climate change continues to impact weather patterns, structures like this play a crucial role in adapting to the evolving challenges of water resource management. Through regular inspections, enforcement, and maintenance, this dam exemplifies the commitment to resilience and safety in the face of changing environmental conditions.

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.
