Summary
Completed in 1979, this earth dam stands at a height of 30 feet and has a hydraulic height of 27 feet, with a storage capacity of 266 acre-feet. The dam spans 850 feet in length and features a controlled spillway with a width of 1 foot.
Despite being classified as having a low hazard potential, the risk assessment for SCS-Pryor Creek Site-31 indicates a very high risk level. The dam has not been rated for its condition assessment and has not been inspected since January 1980, with an inspection frequency of 5 years. With emergency action plans and risk management measures not currently in place, there is a need for increased attention to the safety and maintenance of this crucial flood control structure along TR-Pryor Creek.
As water resource and climate enthusiasts, it is essential to monitor and advocate for the proper management and maintenance of dams like SCS-Pryor Creek Site-31 to ensure the safety of surrounding communities and the effective mitigation of flood risks. With the potential for high risk and the lack of recent inspections, it is crucial for state and federal agencies to prioritize the assessment and maintenance of this dam to protect both the environment and residents in the Mayes County area.

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.
