Summary
Constructed in 1979 by KALMAN & ASSOCIATES, this state-regulated dam stands at a height of 38 feet and has a hydraulic height of 33 feet, providing a maximum storage capacity of 6,994 acre-feet. With a normal storage capacity of 3,000 acre-feet and a surface area of 370 acres, this dam serves as a crucial infrastructure in managing water resources in the region.
The dam is situated on the Oil Branch Creek and is under the jurisdiction of the Oklahoma Water Resources Board. With a significant hazard potential and a fair condition assessment, the dam poses a very high risk, making regular inspections and maintenance crucial. The controlled spillway and valve outlet gate ensure efficient water discharge and flow control during emergencies, highlighting the dam's importance in flood risk management. Despite its age, SCS-Upper Bayou Site-10m continues to play a vital role in water resource management and climate resilience efforts in the area.
Managed by the Natural Resources Conservation Service, this dam not only serves as a critical flood risk reduction infrastructure but also contributes to the overall water management strategies in the region. As climate change impacts continue to pose challenges to water resources, the maintenance and upkeep of SCS-Upper Bayou Site-10m are essential to ensure its continued effectiveness in mitigating flood risks and safeguarding the surrounding communities.

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.
