Summary
The primary purpose of this dam is flood risk reduction along the TR-Finn Creek. With a height of 28 feet and a length of 1250 feet, the dam has a storage capacity of 206 acre-feet and a normal storage level of 46 acre-feet.
Despite being rated as low hazard potential, the risk assessment for SCS-Finn Creek Site-023 indicates a very high risk level. The dam features a controlled spillway, valve outlet gates, and stone core foundation. The dam is under the jurisdiction of the Oklahoma Water Resources Board and is subject to state permitting, inspection, and enforcement. Although the last inspection was conducted in 1980, the dam is maintained in a condition assessed as "not rated."
For water resource and climate enthusiasts, SCS-Finn Creek Site-023 presents an intriguing case study of a state-regulated dam with a significant flood risk reduction purpose. The dam's location in a high-risk area underscores the importance of regular inspections and maintenance to ensure its continued efficacy in protecting the surrounding community from potential flooding events. Further research into the risk management measures and potential modifications for this dam could offer valuable insights for improving its resilience to changing climate conditions and increasing water resource challenges in the region.

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.
