Summary
Standing at a height of 23 feet with a length of 630 feet, this dam has a storage capacity of 109 acre-feet and a normal storage of 43 acre-feet. With a controlled spillway and a low hazard potential, this dam serves the primary purpose of flood risk reduction for the local community.
Although the dam has not been inspected since January 1980, it is maintained by the state regulatory agency OWRB and is subject to state permitting, inspection, and enforcement. Despite not having a current condition assessment, the dam is considered to have a very high risk assessment rating of 1, highlighting the importance of regular inspections and maintenance to ensure the safety and effectiveness of the structure. The dam features a single valve outlet gate and is constructed with stone core and soil foundation, demonstrating a blend of traditional and modern engineering techniques to mitigate flood risks in the area.
Overall, SCS-Finn Creek Site-104 is a vital piece of infrastructure in McClain County, Oklahoma, providing essential flood risk reduction measures for the surrounding community. As water resource and climate enthusiasts, it is crucial to monitor and support the ongoing maintenance and inspection efforts of this dam to ensure its continued effectiveness in protecting against potential flooding events along Second Creek.

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.
