Summary
Completed in 1963, this Earth-type dam stands at a height of 32 feet with a hydraulic height of 28 feet and a length of 1030 feet. It has a storage capacity of 731 acre-feet and serves as a crucial flood risk reduction infrastructure in the region.
With a controlled spillway type and a low hazard potential, this dam is equipped with a single valve outlet gate and has not been inspected since 1980 due to its good condition assessment. Despite its very high risk assessment rating, the structure has not been modified in recent years and does not currently have an emergency action plan in place. Owned by the state and regulated by the Oklahoma Water Resources Board, SCS-Cherokee Sandy Site-02 plays a vital role in managing water resources and climate-related challenges in the area.
In the event of any emergencies, Tom Cole (R) represents the area in Congress, providing a point of contact for any necessary actions. As water resource and climate enthusiasts, understanding the significance of structures like SCS-Cherokee Sandy Site-02 is crucial for promoting sustainable water management practices and ensuring the safety and well-being of communities 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.
