Summary
Constructed in 1969 by the USDA NRCS, this flood risk reduction structure stands at a height of 31 feet and spans 1600 feet in length. With a storage capacity of 822 acre-feet, it serves the primary purpose of flood risk reduction and is equipped with a controlled spillway and a single valve outlet gate.
Despite being rated as having a low hazard potential, this dam is considered to have a very high risk due to its age and lack of recent inspection data. The dam has not been assessed for its current condition, and there is limited information available on emergency action plans or risk management measures in place. However, the presence of state regulation and inspection indicates a level of oversight for ensuring the safety and functionality of the structure.
As water resource and climate enthusiasts, the SCS-Little Wewoka Creek Site-05 presents an intriguing case study for examining the management and maintenance of aging infrastructure in the face of increasing environmental challenges. The dam's location in a high-risk area underscores the importance of proactive risk assessment and emergency preparedness measures to protect downstream communities and ecosystems. Further research and monitoring of this site could provide valuable insights into the intersection of water resource management, climate resilience, and infrastructure sustainability.

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.
