Summary
Built in 1959 by USDA NRCS, this structure serves the primary purpose of flood risk reduction along the TR-South Fork Cavalry Creek. With a height of 30 feet and a length of 625 feet, the dam has a storage capacity of 524 acre-feet, with a normal storage of 138 acre-feet and a surface area of 23 acres.
Despite being rated as having a low hazard potential, the risk assessment for SCS-Cavalry Creek Site-11 indicates a very high risk level. The dam is equipped with a controlled spillway and one valve outlet gate. The last inspection was conducted in 1980, with an inspection frequency of 5 years. The dam's condition is currently not rated, and there is no Emergency Action Plan (EAP) in place. Overall, this site presents an intriguing opportunity for water resource and climate enthusiasts to explore and study the intersection of dam infrastructure, risk management, and environmental conservation in Oklahoma.

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.
