Summary

Completed in 1960, this earth dam stands at a height of 38 feet and spans a length of 1220 feet. With a maximum storage capacity of 400 acre-feet and a normal storage of 105 acre-feet, this structure plays a crucial role in managing water flow and reducing flood risks in the area.

Despite its low hazard potential, the dam at SCS-Turkey Creek Site-01 has been identified as having a very high risk level, emphasizing the importance of regular inspections and maintenance. With a controlled spillway type and one valve outlet gate, this dam is equipped to handle a maximum discharge of 2046 cubic feet per second. While it has not been rated for condition assessment, the dam remains a key asset in the region's water resource management and climate resilience efforts.

As one of the key flood risk reduction structures in the area, SCS-Turkey Creek Site-01 serves as a vital component of the state's water infrastructure, regulated by the OWRB and inspected for safety and functionality. With its strategic location and design by the NRCS, this dam showcases the collaborative efforts of various agencies in safeguarding communities against potential flooding events. Despite its age, this dam continues to play a critical role in water resource management and climate adaptation strategies in Oklahoma.

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.
