Summary

Completed in 2001, this earth dam stands at a height of 39 feet and has a length of 1200 feet, providing a maximum storage capacity of 981 acre-feet. With a primary purpose of flood risk reduction, the dam serves the community by regulating water flow and protecting surrounding areas from potential inundation.

Managed by the Texas Commission on Environmental Quality (TCEQ), the Choctaw Creek WS NRCS Site 30r is subject to state regulation, permitting, inspection, and enforcement to ensure its structural integrity and operational efficiency. Despite being rated as "Not Available" in terms of hazard potential and "Not Rated" in condition assessment, the dam is considered to have a moderate risk level of 3, prompting the need for ongoing risk management measures. The presence of uncontrolled outlet gates and spillway width of 100 feet further enhance the dam's capacity to handle potential overflow events and protect downstream areas.

While the Choctaw Creek WS NRCS Site 30r currently does not have an Emergency Action Plan (EAP) in place, its strategic location and design elements contribute to effective flood risk mitigation and water resource management in the region. With a surface area of 24.7 acres and a drainage area of 2.11 square miles, this structure serves as a critical infrastructure for safeguarding communities against the impacts of extreme weather events and ensuring the sustainable use of water resources in Grayson County, Texas.

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.
