Summary

Completed in 1968, this earth dam stands at a height of 41 feet and spans 450 feet in length, with a maximum storage capacity of 657 acre-feet. The dam, situated on TR-Coon Creek, is regulated by the Oklahoma Water Resources Board and is subject to state permitting, inspection, and enforcement to ensure its safety and functionality.

Despite its low hazard potential, SCS-Caney Coon Creek Site-3 has a very high risk rating, indicating the importance of ongoing risk management measures. The dam features a controlled spillway and a valve outlet gate, with a maximum discharge capacity of 1250 cubic feet per second. While the dam's condition assessment is currently not rated, regular inspections are conducted every five years to monitor its performance and safety. With its strategic location and role in flood risk reduction, SCS-Caney Coon Creek Site-3 serves as a critical infrastructure asset in protecting the surrounding area from potential flooding events.

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.
