Summary

Liberty, Ohio, is a privately-owned earth dam built in 2010 for recreational purposes. The dam stands at a height of 30.5 feet and provides a maximum storage capacity of 240 acre-feet, with a normal storage level of 210 acre-feet. The dam creates a surface area of 22.2 acres and serves as a popular spot for outdoor activities such as boating, fishing, and picnicking.

Despite its recreational benefits, Lake Damascus Dam poses a high hazard potential and has been rated as being in poor condition. The dam is regulated by the Department of Natural Resources in Ohio, with regular inspections conducted to ensure its safety. The last inspection was carried out in October 2020, with a scheduled inspection frequency of every 5 years to assess any necessary maintenance or repairs.

Lake Damascus Dam is situated on an unnamed tributary to Dry Creek and falls under the jurisdiction of the Louisville District. With a congressman representative of Bob Gibbs (R), the dam plays a crucial role in water resource management in the area. While it offers a picturesque setting for outdoor enthusiasts, efforts must be made to improve its condition and reduce the potential hazards associated with its operation.

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.
