Summary
Completed in 1966, this dam stands at a height of 39 feet and has a length of 625 feet, providing a maximum storage capacity of 193 acre-feet. With a controlled spillway and a low hazard potential, this dam plays a crucial role in managing water resources in the region.
Despite being built over five decades ago, SCS-Finn Creek Site-027 continues to be inspected regularly by the Oklahoma regulatory agency OWRB to ensure its structural integrity and functionality. With only one outlet gate and a valve system in place, this dam is equipped to manage a maximum discharge of 700 cubic feet per second during flood events. The risk assessment for this dam indicates a very high risk level, highlighting the importance of ongoing monitoring and maintenance to mitigate potential hazards and safeguard the surrounding community.
In the realm of water resource and climate management, SCS-Finn Creek Site-027 serves as a critical infrastructure for flood control and water storage in the area. As climate change continues to impact weather patterns and increase the frequency of extreme weather events, the role of such dams becomes even more significant in ensuring the resilience of communities and ecosystems against potential flooding and water-related risks.

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.
