Summary

This 32-foot tall dam, with a hydraulic height of 29 feet, serves to control the flow of water and protect the surrounding area from potential flooding events. The dam has a normal storage capacity of 24 acre-feet and a maximum storage capacity of 401 acre-feet, making it an essential piece of infrastructure for managing water resources in the region.

With a low hazard potential and a very high risk assessment rating, SCS-Kadashan Bottom Site-5 is subject to regular state inspection, permitting, and enforcement by the Oklahoma Water Resources Board (OWRB). The dam features a controlled spillway with a width of 1 foot and an outlet gate for water release. Despite its age, the dam's condition assessment is currently listed as "Not Rated," indicating a need for further evaluation to ensure its continued functionality and safety in the face of potential climate impacts such as increased precipitation events and changing water dynamics in the region.

In the event of an emergency, the dam's emergency action plan (EAP) status and risk management measures are not currently specified, suggesting a potential area for improvement in the dam's overall resilience to climate-related hazards. As a key piece of infrastructure for flood risk reduction in the area, ongoing monitoring and maintenance of SCS-Kadashan Bottom Site-5 are crucial to ensuring its effectiveness in protecting the local community and environment from the impacts of extreme weather events and changing hydrological conditions.

Dam Data Reference

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.
