Scs-Finn Creek Site-011 Reservoir Report
Last Updated: February 26, 2026
SCS-Finn Creek Site-011 is a state-regulated earth dam located in Maysville, Oklahoma, along Second Creek.
Summary
Constructed in 1966 by the USDA NRCS, this dam stands at a height of 41 feet and spans a length of 1620 feet, with a storage capacity of 1258 acre-feet. Its primary purpose is flood risk reduction, serving as a vital infrastructure to protect the surrounding area from potential water damage.
With a low hazard potential and a very high risk assessment rating, SCS-Finn Creek Site-011 is equipped with a controlled spillway and one outlet valve for efficient water management. While the dam's condition assessment is not rated, it undergoes inspections every 5 years to ensure its structural integrity and functionality. Despite its age, this dam continues to play a crucial role in safeguarding the community against potential flooding events, highlighting the importance of maintaining and monitoring water resource infrastructure in the face of changing climate conditions.

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.
