Summary
With a height of 25 feet and a storage capacity of 40 acre-feet, this dam sits on the TR-SMITH BRANCH river/stream and covers a surface area of 3 acres. Despite its small size, the dam has a high hazard potential, making it crucial for proper maintenance and management.
Owned and operated by a private entity, Lehar Lake Dam does not fall under state jurisdiction or regulation, posing potential risks to the surrounding community in the event of a failure. With no recent inspection or condition assessment, the dam's current condition is unknown and it is not rated for its structural integrity. Although it may provide recreational opportunities, the lack of oversight and maintenance raises concerns about its safety and long-term viability as a water resource in the area.
For water resource and climate enthusiasts, Lehar Lake Dam serves as a reminder of the importance of proper dam management and maintenance to ensure public safety and environmental protection. With its high hazard potential and lack of regulatory oversight, it underscores the need for increased monitoring and assessment of smaller dams to prevent potential disasters and preserve water resources for future generations.

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.
