Summary
Completed in 1979, this dam stands at a height of 33 feet with a hydraulic height of 30 feet, providing a maximum storage capacity of 714 acre-feet and a normal storage of 145 acre-feet. With a controlled spillway and a low hazard potential, this dam serves as a critical infrastructure for managing water resources in Rogers County.
Managed by the OWRB and regulated by the state of Oklahoma, SCS-Pryor Creek Site-24 boasts a very high risk assessment rating of 1, indicating the importance of its role in mitigating flood risks in the region. Despite its age, the dam remains in good condition with a comprehensive inspection frequency of 5 years. Equipped with a single valve outlet gate, this dam plays a vital role in protecting the surrounding community from potential flooding events, demonstrating the importance of sustainable water resource management in the face of climate change challenges.
As a part of the larger flood risk reduction strategy in the area, SCS-Pryor Creek Site-24 represents a collaborative effort between state and federal agencies, highlighting the importance of effective dam design and maintenance in ensuring the safety and resilience of communities in the face of changing climate patterns. With a strong foundation and stone core, this dam stands as a testament to the ongoing commitment to water resource management and climate adaptation in Oklahoma.

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.
