Summary
Standing at a height of 39 feet and stretching 850 feet in length, this dam has a storage capacity of 116 acre-feet and a maximum discharge of 540 cubic feet per second. Despite being categorized as having low hazard potential, it is considered to have a very high risk level, emphasizing the importance of proper risk management measures.
Managed by the Oklahoma Water Resources Board (OWRB), this dam has a controlled spillway type and is equipped with a single valve outlet gate for water release. While the dam structure itself is in good condition, it has not been inspected since 1980, highlighting the need for updated assessments and maintenance. With a risk assessment rating of 1, it is crucial for emergency action plans to be prepared and regularly reviewed to mitigate potential risks and ensure the safety of surrounding communities in the event of a dam failure. Water resource and climate enthusiasts would find SCS-Bear-Hybarger Site-6 to be a noteworthy site for further study and monitoring in the realm of flood control and dam safety.

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.
