Summary
Built in 1971 by the USDA NRCS, this earth dam stands at 17 feet high and spans 775 feet in length. With a storage capacity of 336 acre-feet, it serves as a recreational area and habitat for local wildlife.
Although John Oneall has a low hazard potential, it is categorized as having a moderate risk level. Despite not having a current condition assessment, the dam is not rated and does not have an Emergency Action Plan in place. While it does not fall under state jurisdiction or regulation, it is important for water resource and climate enthusiasts to monitor its risk management measures closely.
With Mike Rogers (R) as the Congressional Representative overseeing this area, John Oneall presents a unique opportunity for enthusiasts to observe the intersection of water resource management and environmental conservation efforts. As a privately owned structure, it serves as a valuable habitat for wildlife in the region and highlights the importance of sustainable practices in maintaining healthy ecosystems.

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.
