Summary
Built in 1967 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction along the YEAGER CREEK. With a height of 36 feet and a length of 3320 feet, this dam has a storage capacity of 1300 acre-feet, providing essential protection to the surrounding area.
Despite being classified as having a low hazard potential, the risk assessment for SCS-Big Wewoka Creek Site-41 indicates a very high risk level. The dam is equipped with a controlled spillway and a single valve outlet gate. The condition assessment for this structure has not been rated, and the last inspection date was in 1980. It is essential for water resource and climate enthusiasts to monitor the risk management measures and emergency action plans for this dam to ensure the safety of the community and surrounding areas in case of any potential hazards.
Overall, SCS-Big Wewoka Creek Site-41 is a vital infrastructure for flood risk reduction in Hughes, Oklahoma. As water resource and climate enthusiasts, it is crucial to stay informed about the condition and maintenance of this dam to mitigate any potential risks and ensure the safety of the community. The collaboration between state agencies, such as OWRB, and the USDA NRCS in the design and construction of this dam highlights the importance of effective water resource management and infrastructure development in the face of changing climate conditions.

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.
