Summary
Owned by the local government and regulated by the Department of Conservation and Recreation, this earth dam stands at a towering 93 feet in height and spans a length of 780 feet. With a storage capacity of 1680 acre-feet and a normal storage level of 63 feet, the dam plays a crucial role in managing water flow and protecting the surrounding area from potential flooding.
Despite its high hazard potential, Lower North River # 83 is currently in fair condition as of the last assessment conducted in June 2018. The dam's emergency action plan (EAP) status and risk management measures are not specified in the available data, but regular inspections are carried out to ensure its continued safety and effectiveness. Situated on Hone Quarry Run, this structure serves as a vital component of the region's water resource infrastructure, highlighting the importance of proper maintenance and monitoring to mitigate potential risks and safeguard the community against flood events.
As a significant feature in the Baltimore District, Lower North River # 83 is a testament to the ongoing efforts to manage water resources and address climate-related challenges in the area. With its role in flood risk reduction and water flow control, this dam underscores the interconnectedness of water management and climate resilience, emphasizing the need for proactive measures to ensure the safety and sustainability of water resources 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.
