Summary
Operated for irrigation purposes, this earth-type dam stands at a height of 25 feet with a length of 585 feet, providing a storage capacity of 195 acre-feet. Situated along the TR-Muddy Boggy Creek, the dam has a low hazard potential and a moderate risk assessment, making it a crucial asset for water resource management in the region.
Managed by the USDA NRCS, Bill Yarbrough serves the Kalahoma Ind Reservation area and is part of the Tulsa District. Despite being privately owned, the dam is not regulated or inspected by the state, highlighting the importance of private entities in maintaining water resources. With a spillway width of 50 feet and a maximum discharge of 428 cubic feet per second, Bill Yarbrough plays a significant role in controlling water flow and ensuring water availability for irrigation purposes.
While not currently rated for its condition, Bill Yarbrough remains a key infrastructure for water management in the region. With its moderate risk assessment and low hazard potential, the dam provides vital water storage and control capabilities along the TR-Muddy Boggy Creek. As a noteworthy example of private ownership in water resource management, Bill Yarbrough exemplifies the collaboration between private entities and government agencies in ensuring sustainable water use and climate resilience.

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.
