Summary
The dam stands at a height of 33 feet and spans 1020 feet, with a storage capacity of 115 acre-feet. Despite being rated as low hazard potential, the risk assessment for the site indicates a very high risk level, warranting attention and potential management measures.
The dam features a controlled spillway and a single valve outlet gate, with a hydraulic height matching the structural height at 33 feet. While the last inspection took place in 1980, with a scheduled frequency of 5 years, the condition assessment remains unrated. The site is under the jurisdiction of OWRB and falls within the Tulsa District of the USACE, emphasizing the importance of continued monitoring and potential updates to emergency action plans and risk management strategies.
Climate and water resource enthusiasts interested in the intersection of infrastructure and environmental stewardship will find SCS-Finn Creek Site-032 an intriguing case study. With its historical significance, ongoing regulatory oversight, and identified risk factors, this site serves as a focal point for discussions on dam safety, emergency preparedness, and sustainable water management practices in the region.

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.
