Summary

Completed in 1970, this dam stands at a height of 35 feet and has a hydraulic height of 32 feet. With a storage capacity of 321 acre-feet and a spillway width of 1 foot, this dam on the TR-Washita River plays a crucial role in managing water flow and reducing flood risks in the area.

Despite being rated as having a low hazard potential, the risk assessment for SCS-Soldier Creek Site-L12 indicates a very high risk level. The dam is equipped with a valve outlet gate and has not been inspected since 1980, with a scheduled inspection frequency of 5 years. While the condition assessment is not rated, the dam is considered to be in a state of unknown condition. Emergency action plans and risk management measures for the dam are not specified, highlighting the need for continued monitoring and maintenance to ensure the safety and effectiveness of this vital water resource infrastructure.

As water resource and climate enthusiasts, it is crucial to recognize the importance of structures like SCS-Soldier Creek Site-L12 in managing water resources and mitigating flood risks in our communities. By staying informed about the condition and maintenance of such dams, we can contribute to the sustainable management of our water systems and ensure the safety of our environment and infrastructure for future generations.

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.
