Summary

Completed in 1971, this earthen dam stands at 87 feet tall with a length of 1200 feet, providing a maximum storage capacity of 2482 acre-feet. With a spillway width of 1 foot and a controlled spillway type, this dam has a high hazard potential and is currently assessed to be in fair condition.

The dam is overseen by the Oklahoma Water Resources Board and falls under state jurisdiction for permitting, inspection, and enforcement. The primary purpose of SCS-Caston Mountain Creek Site-1 is flood risk reduction, serving the local community in VICTOR by mitigating potential flooding events. Despite its age, the dam continues to meet operational standards with a valve outlet gate and a maximum discharge capacity of 3760 cubic feet per second.

In the event of an emergency, the dam is equipped with an emergency action plan, although specific details on its preparedness and risk management measures are not disclosed. With a very high risk assessment rating and a history of state regulatory compliance, SCS-Caston Mountain Creek Site-1 remains a crucial infrastructure for water resource management and climate resilience in the region.

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.
