Summary

Built in 1969 by the USDA NRCS, this earth dam stands at a height of 50 feet with a length of 3560 feet, providing a maximum storage capacity of 3983 acre-feet.

With a drainage area of 8.03 square miles, the dam has a spillway width of 200 feet and can discharge up to 7620 cubic feet per second. The primary purpose of the dam is flood risk reduction, serving as a critical infrastructure for the local government in mitigating potential disasters. Despite being last inspected in 1975, the dam's hazard potential is currently listed as "Not Available" and its condition assessment is "Not Rated."

While Rush Creek WS SCS Site 12 Dam may not have been examined recently, its moderate risk level and robust design speak to its importance in safeguarding the surrounding area from potential flooding events. The dam's association with the Texas Commission on Environmental Quality (TCEQ) ensures ongoing state regulation, inspection, and enforcement to uphold its structural integrity and functionality for years to come. Water resource and climate enthusiasts will find this dam a compelling example of effective flood risk management in action.

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.
