Summary
Completed in 1960, this dam stands at a height of 22 feet and has a length of 2290 feet, with a storage capacity of 1260 acre-feet and a normal storage of 353 acre-feet. It is situated on TR-Little Peavine Creek and is under the jurisdiction of the Oklahoma Water Resources Board.
Despite being classified as having a low hazard potential, the risk assessment for SCS-Peavine Creek Site-09 is rated as very high, indicating the importance of effective risk management measures. The dam features a controlled spillway with a width of 2 feet and is equipped with one valve outlet gate. Although last inspected in 1980, with an inspection frequency of 5 years, the condition assessment of this structure is currently listed as not rated, emphasizing the need for updated assessments to ensure its safety and functionality in the face of changing climate conditions.
With climate change impacting water resources and increasing the frequency and intensity of extreme weather events, the SCS-Peavine Creek Site-09 serves as a critical infrastructure for mitigating flood risks in the region. As water resource and climate enthusiasts, it is essential to monitor and assess the condition of such structures to ensure their resilience in the face of evolving environmental challenges and to protect communities and ecosystems downstream from potential hazards.

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.
