Summary
Built in 1967 by USDA NRCS, this dam stands at a height of 30 feet and spans a length of 1140 feet. It has a storage capacity of 426 acre-feet, with a normal storage volume of 47 acre-feet. The dam is situated on TR-Gaddis Creek, which is under the jurisdiction of the Oklahoma Water Resources Board.
Despite being classified as having a low hazard potential, SCS-Finn Creek Site-035 is deemed to have a very high risk, with a risk ranking of 1. The dam is equipped with a controlled spillway and a single valve outlet gate. While the condition of the dam is currently not rated, it undergoes inspections every 5 years, with the last recorded inspection dating back to January 1, 1980. Congressman Tom Cole represents the district where the dam is located, and the Tulsa District is responsible for its management.
Water resource and climate enthusiasts will find SCS-Finn Creek Site-035 to be an intriguing case study, showcasing the importance of maintaining and regulating dams for flood risk reduction. The information provided offers valuable insights into the design and construction of the dam, as well as its current state and risk assessment. With its strategic location in an area prone to flooding, this dam serves as a critical infrastructure for managing water resources and mitigating potential hazards.

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.
