Scs-Big Kiowa Creek Site-3 Reservoir Report
Last Updated: December 7, 2025
Located in Beckham County, Oklahoma, the SCS-Big Kiowa Creek Site-3 is a state-regulated earth dam constructed in 1953 by the USDA NRCS for the primary purpose of flood risk reduction along the TR-Big Kiowa Creek.

Summary
With a dam height of 34 feet and a length of 1250 feet, this structure provides a storage capacity of 907 acre-feet, with a normal storage level of 165 acre-feet and a maximum discharge of 770 cubic feet per second. The dam features a controlled spillway and one valve outlet gate for water management.
Despite its low hazard potential, the SCS-Big Kiowa Creek Site-3 is classified as having a very high risk due to its proximity to populated areas. While the dam's condition is currently not rated, it undergoes inspection every 5 years by the OWRB to ensure its safety and effectiveness in flood control. Although the emergency action plan (EAP) status and risk management measures are not specified, the dam's critical role in protecting downstream communities underscores the importance of ongoing monitoring and maintenance to mitigate potential risks associated with its operation.

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.
