Summary
With a primary purpose of flood risk reduction, this dam on the TR-Finn Creek stands at a height of 26 feet and has a storage capacity of 210 acre-feet. The dam, with a fair condition assessment, is equipped with a controlled spillway and a single valve outlet gate.
Despite its fair condition, SCS-Finn Creek Site-033 poses a high hazard potential due to its location and design. The dam, with a hydraulic height matching its structural height of 26 feet, has a very high risk assessment rating of 1. It is inspected by the state regulatory agency, OWRB, with regularity to ensure its safety and functionality. The dam's risk management measures and emergency preparedness plans are crucial aspects to monitor for the safety of the surrounding community.
To water resource and climate enthusiasts, SCS-Finn Creek Site-033 serves as a significant structure in the Tulsa District, contributing to flood risk reduction along TR-Finn Creek. With its stone core and soil foundation, the dam's design by the Natural Resources Conservation Service reflects a commitment to sustainable water management practices. As efforts continue to maintain the dam's integrity and safety, its role in protecting the local area from potential inundation and its high hazard potential underscore the importance of ongoing monitoring and risk management measures.

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.
