Summary

This dam, designed by URS, was completed in 1960 and serves the primary purpose of flood risk reduction along the tributary to Sand Creek. With a height of 48 feet and a hydraulic height of 44 feet, this dam has a storage capacity of 950 acre-feet and a surface area of 49 acres.

Managed by the Natural Resources Conservation Service, SCS-Turkey Creek Site-09 has a controlled spillway with a width of 2 feet and a valve outlet gate. The dam has been inspected for its fair condition, high hazard potential, and very high risk assessment rating. While the last inspection was conducted in September 2011, the dam is regulated and permitted by the Oklahoma Water Resources Board, with state jurisdiction and enforcement in place.

Located in Washita County, Oklahoma, SCS-Turkey Creek Site-09 provides vital flood protection for the surrounding area and is monitored for any necessary maintenance or risk management measures. The dam's strategic position and design make it a crucial asset in safeguarding against potential flooding events, highlighting the importance of water resource management and climate resilience in the region.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
