Summary
Completed in 1960, this earth dam stands at a height of 20 feet and has a storage capacity of 208 acre-feet. With a controlled spillway and valve outlet gate, the dam is designed to handle a maximum discharge of 1072 cubic feet per second.
Despite being rated as low hazard potential and not having a condition assessment, the risk assessment for SCS-Little Deep Fork Creek Site-11 reveals a very high risk level, indicating the need for careful monitoring and management. The dam is under the jurisdiction of the Oklahoma Water Resources Board and is inspected every five years. The surrounding area, Creek County in Oklahoma, is prone to flooding, making the flood risk reduction provided by this dam crucial for protecting the community and infrastructure.
In the event of an emergency, the dam does not have an Emergency Action Plan (EAP) in place, highlighting a potential area of improvement for risk management. With its strategic location on TR-E Spring Creek and affiliation with the Natural Resources Conservation Service, SCS-Little Deep Fork Creek Site-11 serves as a vital piece of infrastructure in safeguarding the local area from flood risks and ensuring water resource management in the region.

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.
