Summary
This dam, standing at a height of 35 feet and with a length of 2310 feet, serves the primary purpose of flood risk reduction along Hybarger Creek. The dam has a storage capacity of 638 acre-feet, with a normal storage capacity of 145 acre-feet and a surface area of 23 acres.
The dam is equipped with a controlled spillway and a single valve outlet gate. Despite being assessed as in fair condition, the dam has a significant hazard potential, with a very high risk assessment rating. The dam is inspected every three years, with the last inspection conducted in November 2011. The state regulatory agency responsible for oversight is the Oklahoma Water Resources Board (OWRB), ensuring that the dam meets safety standards and is in compliance with state regulations.
Overall, SCS-Bear-Hybarger Site-3a plays a crucial role in mitigating flood risks in McClain County, Oklahoma, and highlights the importance of proper dam maintenance and regulation in safeguarding water resources and communities from the impacts of extreme weather events and climate change. Its strategic location on Hybarger Creek, along with its design and structural features, demonstrate how effective infrastructure can help manage water resources and enhance resilience in the face of environmental challenges.

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.
