Summary
Completed in 1960, this earth dam stands at 23 feet tall and spans 1170 feet, providing a maximum storage capacity of 585 acre-feet. The dam's spillway is controlled, with a width of 1 foot and the ability to handle a maximum discharge of 2510 cubic feet per second.
The dam's hazard potential is classified as significant, with a fair condition assessment as of the last inspection in September 2011. Despite its age, the risk assessment for this structure is very high, emphasizing the importance of regular maintenance and monitoring to ensure its continued functionality. With a designated emergency action plan yet to be prepared, there is a need for proactive measures to mitigate risks associated with this critical infrastructure.
Located in Creek County, Oklahoma, this dam on TR-E SRPING CR is under the oversight of OWRB and has a state permit for operation and inspection. As an essential component of flood risk management in the area, SCS-Little Deep Fork Creek Site-15 serves as a vital water resource for the community. Climate and water resource enthusiasts would find this site intriguing for its historical significance and ongoing management challenges in the face of increasing climate variability and extreme weather events.

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.
