Summary
Completed in 1967, this earth dam stands at a height of 36 feet and spans a length of 1420 feet, with a storage capacity of 450 acre-feet. The dam is situated on the TR-Gaddis Creek and is under the jurisdiction of the Oklahoma Water Resources Board.
Despite being classified as having a high hazard potential, the dam is currently in fair condition and has a controlled spillway with a width of 1 foot. With a maximum discharge capacity of 2084 cubic feet per second, SCS-Finn Creek Site-036 serves as a critical infrastructure for mitigating flooding risks in the area. However, the dam's risk assessment is rated as very high, indicating a need for ongoing monitoring and potential risk management measures to ensure the safety of downstream communities.
As an essential component of the flood control system in the region, SCS-Finn Creek Site-036 plays a crucial role in protecting nearby residents and infrastructure from potential flood events. With its strategic location and design features, this dam serves as a key asset in the overall water resource management and climate resilience efforts in McClain County, Oklahoma.

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.
