Summary
Completed in 1968, this dam stands at a height of 42 feet with a length of 2840 feet, providing a maximum storage capacity of 2279 acre-feet. With a controlled spillway and one outlet valve, this dam has a low hazard potential but is considered to have a very high risk due to its age and lack of recent condition assessments.
Despite its age, SCS-Little Deep Fork Creek Site-21r remains in good condition and meets state regulatory standards for inspection, permitting, and enforcement. The dam's purpose of flood risk reduction ensures protection for the surrounding area, with a normal storage capacity of 230 acre-feet and a surface area of 48 acres. While the dam has not been modified in recent years and lacks an Emergency Action Plan, its design and construction by the Natural Resources Conservation Service demonstrate a commitment to water resource management and climate resilience in the region.
As a vital component of the water infrastructure in Creek County, Oklahoma, SCS-Little Deep Fork Creek Site-21r serves as a key asset for managing flood risk and protecting downstream areas from potential inundation. With its sturdy earth construction and controlled spillway, this dam plays a crucial role in regulating the flow of Catfish Creek and ensuring the safety of nearby communities. As climate change continues to impact water resources, the maintenance and monitoring of structures like SCS-Little Deep Fork Creek Site-21r are essential for sustainable water management practices and long-term resilience against 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.
