Summary

This earth dam stands at a height of 50 feet and stretches 342 feet in length, with a storage capacity of 79.6 acre-feet. Completed in 2001, it serves the primary purpose of recreation along TR Dunkard Creek.

Managed by the Pennsylvania Department of Environmental Protection, Leonard George is subject to state regulation, inspection, and enforcement to ensure its safety and compliance with environmental standards. With a low hazard potential and a satisfactory condition assessment, this dam poses minimal risk to surrounding areas. The last inspection in July 2019 found the structure to be in good standing, with a maintenance frequency of every 5 years.

For water resource and climate enthusiasts, Leonard George serves as a prime example of a privately owned recreational dam that contributes to the local landscape while adhering to state regulations. Its design and construction reflect a commitment to safety and environmental stewardship, making it a valuable asset for both recreation and conservation efforts in the region.

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.
