Summary
The dam stands at a height of 24 feet and spans a length of 1325 feet, with a storage capacity of 822 acre-feet. With a controlled spillway and a low hazard potential, this dam plays a crucial role in managing the flow of the TR-Little Wewoka Creek and protecting the surrounding area from potential flooding.
Despite being last inspected in 1980, SCS-Little Wewoka Creek Site-07 has a very high risk assessment rating of 1, emphasizing the importance of regular monitoring and maintenance. The dam features a single valve outlet gate and has not been modified in recent years. While the condition assessment is currently not rated, the state agency OWRB is responsible for permitting, inspecting, and enforcing regulations related to the dam, ensuring its continued operation and safety within the community.
As an essential component of the flood control infrastructure in Hughes County, Oklahoma, SCS-Little Wewoka Creek Site-07 serves as a vital resource for water resource and climate enthusiasts. With its strategic location and design by the USDA NRCS, this earth dam exemplifies the collaborative efforts between state and federal agencies in managing water resources and reducing flood risks in the region. Despite its age, the dam's low hazard potential and capacity for storing water make it a valuable asset for both the local community and the broader ecosystem.

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.
