Summary
The dam, primarily designed for purposes other than flood control or irrigation, stands at a height of 18 feet and is classified as an earth dam. While the hazard potential associated with the dam is rated as low, the overall risk assessment is moderate.
Owned and regulated by a private entity in Kentucky, O'Bryan Dam falls under the jurisdiction of the Kentucky Division of Water, with state permitting, inspection, and enforcement in place. The dam features an uncontrolled spillway type, with a surface area of 9.6 acres and a drainage area of 0.07 square miles. Despite not having a current condition assessment rating, the dam undergoes inspections every five years, with the last inspection conducted in June 2012.
Although O'Bryan Dam does not pose a significant hazard, its role in water resource management and climate resilience in the region is crucial. With its strategic location and design, the dam serves as a key infrastructure asset for water storage and management, contributing to the overall resilience of the area against potential risks and emergencies.

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.
