Summary
This 26-foot high dam with a length of 710 feet has a storage capacity of 228 acre-feet and a maximum discharge of 680 cfs. The dam is classified as low hazard potential with a very high risk assessment rating.
Located in Creek County, the dam is owned by the state and falls under the jurisdiction of the Oklahoma Water Resources Board (OWRB). Despite being in operation for over six decades, the dam's condition assessment is not rated, and the last inspection was conducted in 1980. The primary purpose of this structure is flood risk reduction, with a controlled spillway and a single valve outlet gate for managing water flow.
For water resource and climate enthusiasts, SCS-Little Deep Fork Creek Site-30 offers a fascinating case study in dam infrastructure management and risk assessment. The data highlights the importance of regular inspections and maintenance to ensure the safety and effectiveness of flood control structures. With its historical significance and ongoing regulatory oversight by the OWRB, this site serves as a valuable resource for understanding the intersection of water management, engineering, and environmental protection in Oklahoma's landscape.

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.
