Summary
Completed in 1981, this dam stands at a height of 30 feet and has a storage capacity of 853 acre-feet. With a low hazard potential and a very high risk assessment rating, this structure plays a crucial role in managing water resources in the area, specifically along the TR-Cottonwood Creek.
Owned by the state and regulated by the Oklahoma Water Resources Board (OWRB), SCS-Upper Bayou Site-05 is equipped with a controlled spillway and a single valve outlet gate. Despite being built with stone core and soil foundation, the dam is currently not rated for its condition. With a drainage area of 1.7 square miles and a maximum discharge capacity of 250 cubic feet per second, this dam serves as a vital infrastructure for mitigating flood risks and ensuring water resource sustainability in the region.
The surrounding community in Oswalt, Oklahoma benefits from the flood protection offered by SCS-Upper Bayou Site-05, with the dam covering a surface area of 19 acres. While the dam has not undergone recent inspections or condition assessments, its emergency action plan status and risk management measures remain unspecified. For water resource and climate enthusiasts, this site serves as a fascinating case study in dam infrastructure and flood risk reduction strategies, highlighting the importance of proactive maintenance and monitoring for sustainable water management practices.

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.
