Summary
Built in 1959 by the USDA NRCS, this earth dam stands at a height of 28 feet and has a length of 350 feet. The dam has a storage capacity of 121 acre-feet and a maximum discharge of 1020 cfs, with a controlled spillway width of 1 foot. Despite being categorized as having a low hazard potential, the risk assessment for this dam is rated as very high (1), highlighting the importance of ongoing monitoring and maintenance.
Situated on TR-South Fork Cavalry Creek in Washita County, SCS-Cavalry Creek Site-07b is under the jurisdiction of the Oklahoma Water Resources Board (OWRB) for permitting, inspection, and enforcement. While the dam's condition assessment is currently not rated, regular inspections are conducted every five years to ensure its structural integrity and safety. The dam features one outlet gate for water release and has not undergone any modifications since its construction, emphasizing the need for continued risk management measures to mitigate potential hazards and safeguard the surrounding community and ecosystem.
With its critical role in flood risk reduction and water resource management, SCS-Cavalry Creek Site-07b serves as a vital infrastructure in the Tulsa District. The dam's presence not only protects the local area from potential flooding but also contributes to the overall resilience of the region against extreme weather events and climate variability. As water resource and climate enthusiasts, understanding the importance of maintaining and monitoring dams like SCS-Cavalry Creek Site-07b is crucial in ensuring the long-term sustainability and safety of our water infrastructure in the face of changing environmental conditions.

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.
