Summary

Designed by USDA NRCS and completed in 1976, this Earth-type dam stands at a height of 22 feet and serves the primary purpose of flood risk reduction. With a storage capacity of 80 acre-feet, the dam has a low hazard potential and a very high risk assessment rating.

Owned by the state of Oklahoma and regulated by the OWRB, SCS-Kadashan Bottom Site-3 features a controlled spillway and a single valve outlet gate. Despite not having a condition assessment rating, the dam has not been inspected since 1980 and is due for inspection every 5 years. In the event of an emergency, the dam does not have an Emergency Action Plan (EAP) prepared, raising concerns about its readiness to handle potential risks.

For water resource and climate enthusiasts, SCS-Kadashan Bottom Site-3 offers a case study in the management and maintenance of dams for flood risk reduction. The dam's location along the TR-ARKANSAS RIVER and its low hazard potential highlight the importance of regular inspections and emergency preparedness measures to ensure the safety and security of surrounding communities. As the dam continues to age, stakeholders may need to consider updates to its risk management measures to address the very high risk assessment rating and mitigate potential hazards.

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.
