Summary
Built in 1963 by the Ralph L. Woolpert Co. from Dayton, Ohio, this earth dam stands at 44.5 feet high and stretches 850 feet in length. It overlooks Caesar Creek, offering a serene setting for outdoor enthusiasts to enjoy water activities and scenic views.
Maintained by the Ohio Department of Natural Resources, the dam has a maximum storage capacity of 4,109 acre-feet and a normal storage of 1,402 acre-feet, covering a surface area of 145 acres. Despite its high hazard potential, the dam's condition is assessed as fair, with inspections conducted every 5 years. The surrounding area boasts a drainage area of 10.9 square miles, ensuring a steady flow of water for recreational purposes while also posing potential risks that are managed through emergency action plans.
Visitors can appreciate the dam's historical significance, its role in water resource management, and its contribution to the local ecosystem. With its picturesque setting and crucial role in flood control and water storage, Lake Shawnee Dam serves as a vital asset for both the community and the environment, embodying the harmony between water resources and climate preservation.

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.
