Summary

This dam stands at a height of 42 feet with a hydraulic height of 38 feet, serving a primary purpose of flood risk reduction. With a storage capacity of 529 acre-feet and a maximum discharge of 2200 cubic feet per second, this dam plays a crucial role in managing water flow and reducing the risk of flooding in the area.

Despite its age, the condition of SCS-Upper Washita Creek Site-054 has not been rated, and it is classified as having low hazard potential. However, a risk assessment has identified a very high risk level, emphasizing the importance of regular inspections and maintenance to ensure the dam's structural integrity and effectiveness in flood risk reduction. With a controlled spillway and a single valve outlet gate, this dam is a key component in the overall water resource management infrastructure in the region.

In the event of an emergency, it is essential for the responsible authorities to have an Emergency Action Plan (EAP) prepared and updated to meet guidelines and ensure the safety of surrounding communities. Regular inspections, risk assessments, and maintenance measures are crucial to managing the very high risk level associated with SCS-Upper Washita Creek Site-054 and maintaining its functionality in flood risk reduction efforts. This dam serves as a vital piece of infrastructure in protecting against potential flooding and safeguarding water resources 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.
