Summary
Built in 1958 by the USDA NRCS, this earth dam stands at a height of 29 feet and has a length of 1270 feet, providing flood risk reduction for the area. With a storage capacity of 392 acre-feet, the dam's spillway type is Controlled, with a maximum discharge of 1100 cubic feet per second.
The condition assessment of SCS-Little Wewoka Creek Site-04 is rated as fair, with a significant hazard potential and a very high risk assessment score of 1. The dam's emergency action plan status and risk management measures are currently unknown, highlighting the need for updated information and potential improvements to ensure the safety and efficiency of the structure. With a designated inspection frequency of 3, it is essential to monitor and maintain the dam regularly to uphold its functionality and protect the surrounding communities from potential risks and hazards.
Overall, SCS-Little Wewoka Creek Site-04 serves as a crucial infrastructure for flood risk reduction in Seminole County, Oklahoma. As a state-regulated dam under the jurisdiction of OWRB, it plays a vital role in managing water resources and protecting the local area from potential flooding events. However, the dam's fair condition assessment and significant hazard potential warrant further attention and potential enhancements to ensure the continued safety and effectiveness of this essential water management structure.

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.
