Summary

With a primary purpose of recreation, this dam stands at a height of 30 feet and has a storage capacity of 128 acre-feet. The dam's hazard potential is rated as low, and its condition assessment is currently listed as "Not Rated." Despite its modest size, Lohmar Lake Dam provides a valuable recreational resource for the local community, offering opportunities for fishing, boating, and wildlife observation.

Managed by private owners, Lohmar Lake Dam is not regulated by the state and does not fall under the jurisdiction of any state regulatory agency. Although it has not been inspected or assessed for condition in recent years, the dam continues to serve as a popular destination for outdoor enthusiasts in the Boone County area. While the dam's emergency action plan status and risk assessment details are currently unavailable, its low hazard potential suggests that it poses minimal risk to surrounding areas in the event of a breach. For water resource and climate enthusiasts, Lohmar Lake Dam represents a prime example of how private ownership can contribute to the preservation and enjoyment of natural resources.

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.
