Summary
With a height of 34 feet and a length of 272 feet, this structure has a storage capacity of 2,945 acre-feet and a spillway width of 2 feet. The dam, built on a soil foundation, serves as a critical infrastructure in managing water resources in the Hughes County area.
Despite being rated as having a low hazard potential, the dam at SCS-Little Wewoka Creek Site-08 is considered to be in very high risk due to its location and associated factors. The structure has not been inspected since 1980, and its condition assessment is currently not rated. Emergency action plans and risk management measures for the dam are also not documented, highlighting the need for updated safety protocols and regular inspections to ensure the continued protection of surrounding communities and water resources.
As a key component in flood risk reduction efforts in the area, SCS-Little Wewoka Creek Site-08 plays a vital role in water resource management in Hughes County. With its design and construction overseen by the Natural Resources Conservation Service, this earth dam provides essential protection against potential flooding events along the TR-Little Wewoka Creek. Moving forward, it is crucial for regulatory agencies and stakeholders to prioritize regular inspections, risk assessments, and emergency preparedness to maintain the integrity and safety of this important infrastructure.

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.
