Summary

This earth dam, designed by USDA NRCS and completed in 2000, stands at a height of 52.5 feet and spans a length of 2162 feet, providing storage of up to 2654 acre-feet in its reservoir. With a drainage area of 4.06 square miles and a maximum discharge capacity of 34000 cubic feet per second, this structure plays a crucial role in managing water flow and mitigating flood risks in the region.

The dam, regulated by the Texas Commission on Environmental Quality (TCEQ), features a spillway type of uncontrolled with a width of 173 feet. Despite being designated as "Fair" in its condition assessment as of April 2021, the site has an inspection frequency of 5 years to ensure its continued reliability. With a moderate risk assessment rating of 3, the dam's emergency action plan (EAP) status and risk management measures are currently not available, highlighting a potential area for improvement in the site's overall emergency preparedness and response capabilities.

With its strategic location and design features, Choctaw Creek WS NRCS Site 8a serves as a vital component in the water resource infrastructure of the area. As climate change impacts continue to pose challenges to water management, understanding and enhancing the resilience of structures like this earth dam will be crucial in ensuring the safety and sustainability of water resources for the communities it serves.

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.
