Summary
Standing at a height of 25.1 feet and spanning 430 feet in length, the dam holds a storage capacity of 48 acre-feet with a normal storage of 34 acre-feet. The dam overlooks Lahmers Lake and is a popular spot for outdoor enthusiasts seeking water-based activities.
Despite its low hazard potential, Lahmers Lake Dam currently has a poor condition assessment, last inspected in July 2020. The dam is under state regulation by the Department of Natural Resources, with permitting, inspection, and enforcement conducted by the agency. While the dam poses minimal risk, its deteriorating condition highlights the importance of regular maintenance and monitoring to ensure the safety of the surrounding community and environment.
As a tributary to Broad Run, Lahmers Lake Dam plays a vital role in water resource management within the area. With its recreational significance and potential impact on the local ecosystem, the ongoing maintenance and assessment of the dam are crucial in preserving its functionality and safety for both residents and wildlife.

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.
