Summary
Built in 1977, this Earth-type structure stands at a height of 25 feet and spans 542 feet in length. With a storage capacity of 50 acre-feet and a maximum discharge rate of 1841 cubic feet per second, Yarbrough Fred serves as a low hazard dam with a very high risk assessment rating.
Although not currently rated for condition assessment, Yarbrough Fred is regulated, inspected, and enforced by the Oklahoma Water Resources Board (OWRB). Despite its low hazard potential, the dam is equipped with a controlled spillway and a single valve outlet gate. The dam's emergency action plan status, risk management measures, and inundation maps remain undisclosed, highlighting a need for further evaluation and preparedness in the event of a potential emergency.
For water resource and climate enthusiasts, Yarbrough Fred presents an intriguing case study in dam infrastructure management. Its location, design, and operational history provide valuable insights into the challenges and considerations involved in maintaining and regulating dams in rural areas. As efforts to address climate change and ensure water resource sustainability continue to evolve, understanding the intricacies of structures like Yarbrough Fred is crucial for informed decision-making and risk mitigation strategies.

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.
