Summary
Constructed in 1960 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction along the TR-Wewoka Creek. With a structural height of 29 feet and a length of 1600 feet, the dam has a maximum storage capacity of 1346 acre-feet and a normal storage capacity of 313 acre-feet.
This dam has a controlled spillway type with a width of 2 feet and an outlet gate consisting of one valve. Despite being classified as having a low hazard potential, the risk assessment for this dam is very high. However, the condition assessment is currently marked as "Not Rated" as the last inspection date was in 1980. Overall, the SCS-Big Wewoka Creek Site-32 plays a crucial role in managing flood risks in the area and is under the jurisdiction of the Oklahoma Water Resources Board.
For water resource and climate enthusiasts, the SCS-Big Wewoka Creek Site-32 presents an intriguing case study in dam management and flood risk reduction. The dam's design and construction by the USDA NRCS highlight the importance of strategic infrastructure in mitigating natural disasters. With its location in Hughes County, Oklahoma, this earth dam serves as a critical structure along the TR-Wewoka Creek, providing valuable storage capacity and flood control measures. As efforts continue to monitor and assess the condition of the dam, its role in protecting the surrounding area from potential flooding events remains paramount.

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.
