Summary
Constructed in 1965 by the USDA NRCS, this dam stands at a height of 32 feet and stretches 990 feet in length. It has a maximum storage capacity of 435 acre-feet and a normal storage of 100 acre-feet, serving as a critical structure along TR-Finn Creek. The dam features a controlled spillway and a single valve outlet gate.
Despite being in fair condition as of the last inspection in 2011, SCS-Finn Creek Site-004 has a significant hazard potential and is classified as having a very high risk level. It is under the jurisdiction of the Oklahoma Water Resources Board (OWRB) and undergoes regular state inspections and enforcement. The dam's risk management measures and emergency action plan status are currently unspecified, highlighting the need for continued monitoring and maintenance to ensure the safety and integrity of this vital flood control structure in the region.
With a congressman as the designated representative for the area and a history of federal funding by the Natural Resources Conservation Service, SCS-Finn Creek Site-004 plays a crucial role in protecting the surrounding community from potential flooding events. As water resource and climate enthusiasts, staying informed about the condition and risk assessment of dams like this one is essential for understanding their impact on local ecosystems and communities, as well as advocating for necessary improvements and safety measures to mitigate potential hazards.

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.
