Summary

Built in 1959 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction in the region. With a height of 45 feet and a hydraulic height of 41 feet, it holds a maximum storage capacity of 492 acre-feet and a normal storage of 130 acre-feet across a surface area of 17 acres. The dam's spillway type is controlled, with a width of 1 foot, and it has one valve outlet gate.

Despite being assessed as in fair condition during its last inspection in 2011, SCS-Fast Runner Creek Site-3 presents a significant hazard potential due to its location and characteristics. The dam's risk assessment indicates a very high risk level, which prompts the need for regular inspections and maintenance to ensure its continued ability to mitigate flood risks effectively. The dam is under the jurisdiction of the Oklahoma Water Resources Board (OWRB) and is subject to state permitting, inspection, and enforcement, highlighting the importance of regulatory oversight in safeguarding water resources and public safety in the area.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
