Summary

Built in 1991 by the USDA NRCS, this earth dam stands at 53 feet tall and spans 1683 feet in length, with a storage capacity of 2545 acre-feet. The dam serves the primary purpose of flood risk reduction for the TR-Iron Ore Creek, with a drainage area of 2.32 square miles.

Maintained by the Texas Commission on Environmental Quality (TCEQ), this dam has undergone regular inspections, with its most recent condition assessment in January 2018 deemed satisfactory. The spillway of the dam is uncontrolled and has a width of 130 feet, with a maximum discharge capacity of 2 cubic feet per second. While the hazard potential is listed as not available, the risk assessment categorizes the dam as moderate (3), indicating a moderate level of risk associated with its operation and maintenance.

As a crucial component of the local government's flood protection infrastructure, Choctaw Creek WS SCS Site 38r Dam plays a significant role in safeguarding the surrounding area from potential flooding events. With its solid design and satisfactory condition, the dam stands as a testament to effective water resource management and climate resilience efforts in the region.

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.
