Summary
Managed by the USDA NRCS, this earth dam stands at a height of 40 feet and was completed in 1960 for the primary purpose of flood risk reduction along the TR-Turkey Creek. With a storage capacity of 340 acre-feet, this dam plays a crucial role in protecting the surrounding area from potential flooding events.
The dam's spillway is controlled and has a width of 1 foot, serving as a vital component in managing water levels during periods of high discharge. Despite being classified as having a high hazard potential, the dam is currently in fair condition and undergoes inspections at a frequency of 1 year. In the event of an emergency, the dam is equipped with a single valve outlet gate for controlled water release. The risk assessment for SCS-Turkey Creek Site-08 indicates a very high level of risk (1) in terms of potential impact and severity.
Overall, SCS-Turkey Creek Site-08 showcases the collaboration between state and federal agencies in ensuring the safety and efficacy of water resource management infrastructure. With its strategic location and design features, this dam serves as a critical asset in mitigating flood risks and protecting the surrounding communities in Washita County, Oklahoma.

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.
