Summary
Completed in 1958, this dam stands at 25 feet tall with a length of 1000 feet and has a storage capacity of 329 acre-feet. The dam is situated on TR-Little Wewoka Creek in Hughes County, Oklahoma, and is under the jurisdiction of the Oklahoma Water Resources Board.
Despite being classified as low hazard potential, the risk assessment for SCS-Little Wewoka Creek Site-10 indicates a very high risk level. The dam has not been inspected since January 1980, with an intended inspection frequency of 5 years. The structure features a controlled spillway with a width of 1 foot and an outlet gate system consisting of a single valve. The dam's condition assessment is marked as "Not Rated," and there is no available information on emergency action plan preparedness or risk management measures.
Water resource and climate enthusiasts interested in the SCS-Little Wewoka Creek Site-10 can explore its historical significance as a flood control infrastructure in Oklahoma. The dam's location within the Tulsa District and its association with the Natural Resources Conservation Service highlight the collaborative efforts in managing water resources and mitigating flood risks in the region. Further research and assessment may be needed to address the identified high-risk factors and ensure the safety and effectiveness of this vital 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.
