Summary
This dam stands at a height of 23 feet with a hydraulic height of 19 feet and a length of 1090 feet, providing a normal storage capacity of 547 acre-feet. Despite being classified as low hazard potential, it has a very high risk assessment rating of 1, indicating the importance of ongoing monitoring and maintenance to ensure its effectiveness in flood control.
Located in the Fort Worth District and under the jurisdiction of the Oklahoma Water Resources Board, SCS-Upper Bayou Site-17 features a controlled spillway and a single valve outlet gate for water management. While the dam's condition is currently not rated, with the last inspection dating back to 1980, its risk management measures and emergency action plan status are not specified. With a capacity to handle a maximum discharge of 1230 cubic feet per second, this dam plays a critical role in protecting the surrounding area from flooding events, highlighting the vital role of infrastructure in water resource management and climate resilience efforts.

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.
