Summary
Completed in 1961, this earthen dam stands 25 feet tall and spans 1750 feet along the TR-Little Wewoka Creek. With a storage capacity of 445 acre-feet and a normal storage level of 65 acre-feet, this structure serves as a vital asset in mitigating potential flooding in the area.
Managed by the OWRB and inspected every five years, this dam boasts a low hazard potential and has not been rated for its current condition. Despite its age, the risk assessment of SCS-Little Wewoka Creek Site-01 indicates a very high risk level, emphasizing the importance of ongoing monitoring and maintenance to ensure its structural integrity. With one valve outlet gate and a controlled spillway, this dam plays a crucial role in protecting the surrounding community from the impacts of extreme weather events and changing climate patterns.
As water resource and climate enthusiasts, the significance of SCS-Little Wewoka Creek Site-01 cannot be understated. Serving as a key component in the state's flood risk reduction strategy, this dam stands as a testament to the collaborative efforts of government agencies and designers in safeguarding communities against the potential dangers of flooding. With its strategic location and design features, this dam remains a critical infrastructure asset in managing water resources and adapting to the challenges posed by a changing climate.

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.
