Summary
Completed in 1963, this dam stands at a height of 27 feet and has a storage capacity of 132 acre-feet, serving as a crucial structure for managing water resources in McClain County. With a controlled spillway and a low hazard potential, this dam ensures the safety and protection of the surrounding area from potential flooding events.
Managed by the Oklahoma Water Resources Board (OWRB), SCS-Bear-Hybarger Site-7 undergoes regular inspections every five years, with the last inspection dating back to 1980. Despite being deemed in "not-rated" condition, the dam's risk assessment is categorized as very high, highlighting the need for continued monitoring and maintenance to uphold its structural integrity. With a single valve outlet gate and a stone core foundation, this dam plays a vital role in flood risk reduction efforts within the Tulsa District, showcasing the collaborative efforts of state and federal agencies in safeguarding communities and natural resources from the impacts of climate variability.
As a key component of the local water infrastructure, SCS-Bear-Hybarger Site-7 exemplifies the importance of effective dam management and regulatory oversight in mitigating flood risks and ensuring the resilience of water resources in Oklahoma. With its historical significance dating back to over five decades, this earth dam serves as a testament to the enduring commitment of stakeholders in protecting communities, ecosystems, and livelihoods from the unpredictable challenges posed by climate change. As climate enthusiasts and water resource advocates, understanding and appreciating the role of structures like SCS-Bear-Hybarger Site-7 is essential in fostering sustainable water management practices for a more resilient future.

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.
