Summary
Standing at a height of 36 feet and a length of 1600 feet, this dam plays a crucial role in managing the water levels of Elm Creek. With a storage capacity of 2854 acre-feet, it helps in controlling the flow of water and reducing the risk of flooding in the area.
Despite its low hazard potential, SCS-Little Wewoka Creek Site-11 is regulated by the Oklahoma Water Resources Board and undergoes regular inspections, with a frequency of every 5 years. The dam features a controlled spillway and a valve outlet gate, ensuring efficient water release in case of excess flow. The risk assessment for this structure indicates a very high risk level, emphasizing the importance of proper management and maintenance to ensure its continued effectiveness in flood risk reduction.
Water resource and climate enthusiasts will appreciate the engineering and design details of SCS-Little Wewoka Creek Site-11, as well as its significant role in protecting the surrounding area from potential floods. This state-regulated dam, located in the Tulsa District, serves as a vital infrastructure for water management in the region and highlights the importance of maintaining and monitoring such structures to ensure the safety and well-being of the community.

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.
