Summary
Completed in 1967, this dam stands at 35 feet in height and stretches 820 feet in length, with a storage capacity of 155 acre-feet. The dam's spillway type is controlled, with a width of 1 foot, and it is equipped with a valve outlet gate for water release.
Despite being assessed as in fair condition during the last inspection in 2011, the SCS-Finn Creek Site-018 poses a high hazard potential due to its location and purpose. With a risk assessment rating of very high (1), the dam requires regular inspections and enforcement by Oklahoma's OWRB to ensure its structural integrity and the safety of downstream communities. The dam's emergency action plan status, inundation maps, and risk management measures are currently not updated, highlighting the importance of continued monitoring and maintenance to mitigate potential risks.
As a critical infrastructure for flood risk reduction in the region, the SCS-Finn Creek Site-018 serves as a reminder of the vital role that earth dams play in water resource management and climate adaptation efforts. With its historical significance and ongoing regulatory oversight, this dam stands as a testament to the collaborative efforts between federal and state agencies to safeguard communities and ecosystems from the impacts of extreme weather events and changing climate patterns.

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.
