Summary
Built in 1963 by the USDA NRCS, this Earth dam stands at a height of 46 feet and stretches 1,840 feet in length. Serving primarily for flood risk reduction, it has a maximum storage capacity of 519 acre-feet and a normal storage capacity of 91 acre-feet. The dam is regulated by the Oklahoma Water Resources Board and undergoes regular state inspections and enforcement to ensure its structural integrity.
Despite being categorized as a low hazard potential structure, the risk assessment for SCS-Bear-Hybarger Site-1y indicates a very high risk level (1). However, the condition assessment is listed as "Not Rated," and the last inspection date recorded was back in 1980. The dam features a controlled spillway and one outlet valve, with no associated locks. While there are no current risk management measures or emergency action plans in place, the dam's location in a high-risk area underscores the importance of regular assessments and preparedness for potential emergencies.
Overall, the SCS-Bear-Hybarger Site-1y dam presents an intriguing case study for water resource and climate enthusiasts. With its historical significance dating back to the 1960s and its crucial role in flood risk reduction in McClain County, Oklahoma, the dam's current risk assessment and lack of recent condition evaluations raise questions about its long-term safety and maintenance. As climate change continues to impact water resources and infrastructure, ensuring the resilience and effectiveness of structures like SCS-Bear-Hybarger Site-1y becomes increasingly vital for the community and surrounding environment.

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.
