Summary
This Earth dam, completed in 1960, spans 1150 feet in length and reaches a height of 20 feet, providing a maximum storage capacity of 395 acre-feet. The dam, situated on the TR-Wewoka Creek, plays a vital role in safeguarding the surrounding areas from potential flooding events.
With a high hazard potential and fair condition assessment, SCS-Big Wewoka Creek Site-07 requires regular inspections and maintenance to ensure its structural integrity and functionality. The dam features a controlled spillway and a valve outlet gate for water release. Despite its age, the dam continues to serve its primary purpose effectively, with a very high risk assessment rating indicating the need for continuous risk management measures.
Managed by the OWRB and falling under state jurisdiction, this dam serves as a testament to the importance of water resource infrastructure in mitigating flood risks and ensuring the safety of communities in the region. As climate change continues to impact precipitation patterns and water availability, the preservation and maintenance of structures like SCS-Big Wewoka Creek Site-07 are essential for sustainable water resource management in Oklahoma.

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.
