Summary
The dam stands at a height of 32 feet with a hydraulic height of 27.1 feet, providing a storage capacity of 158 acre-feet. The dam's primary purpose and specific construction year are not listed, but it serves as an essential structure for water resource management in the region.
With a surface area of 8.65 acres and a normal storage capacity of 93 acre-feet, Johnny Owen Lake Dam plays a crucial role in regulating water flow and storage in the area. Despite being uncontrolled, the spillway type and outlet gates are designed to manage water levels efficiently. The dam's hazard potential is undetermined, with a moderate risk assessment rating of 3, indicating the need for ongoing monitoring and potential risk management measures.
While the dam's condition assessment is listed as "Not Rated," regular inspections are conducted every five years to ensure its structural integrity and operational effectiveness. With its strategic location in Barnesville and contribution to water resource management in the area, Johnny Owen Lake Dam stands as a vital infrastructure for climate and water resource enthusiasts to monitor and appreciate.

Dam Data Reference
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.
