Summary
Built in 1961 by the USDA NRCS, this dam stands at a height of 30 feet and has a length of 670 feet, providing a storage capacity of 411 acre-feet. The dam is primarily made of stone with a soil foundation and features a controlled spillway with a width of 1 foot.
With a drainage area of 1.49 square miles, SCS-Little Wewoka Creek Site-06 has a maximum discharge capacity of 1615 cubic feet per second. Despite being classified as having a low hazard potential, the dam is considered to have a very high risk due to its condition not being rated and its last inspection dating back to 1980. The structure is equipped with a valve outlet gate and is subject to state permitting, inspection, and enforcement by the OWRB.
Water resource and climate enthusiasts will find SCS-Little Wewoka Creek Site-06 to be an interesting case study in flood risk management and dam safety. The structure's location in the Tulsa District of Oklahoma, its association with the Little Wewoka Creek, and its purpose of flood risk reduction highlight the importance of sustainable water resource management practices in mitigating natural disasters and protecting communities. The data provided on the dam's design, construction, and maintenance offer valuable insights into the intersection of water infrastructure, regulatory oversight, and emergency preparedness in the face of climate change impacts.

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.
