Scs-Finn Creek Site-005 Reservoir Report
Last Updated: December 13, 2025
SCS-Finn Creek Site-005, located in McClain County, Oklahoma, was designed by the USDA NRCS and completed in 1964 with a primary purpose of flood risk reduction along the TR-Finn Creek.

Summary
This earth dam stands at a height of 28 feet and stretches 1550 feet in length, providing a storage capacity of 604 acre-feet with a normal storage of 103 acre-feet. The controlled spillway type and valve outlet gate contribute to its low hazard potential.
Despite being last inspected in 1980, the dam at SCS-Finn Creek Site-005 has a very high risk rating due to its age and lack of recent assessments. However, with state regulation, permitting, inspection, and enforcement in place, the dam continues to serve its flood risk reduction function effectively. The dam's association with the Oklahoma Water Resources Board (OWRB) ensures that it meets state guidelines and remains a crucial infrastructure for protecting the surrounding area from potential inundation events.

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.
