Summary

Standing at a height of 29 feet and spanning a length of 1675 feet, this earth dam plays a crucial role in managing water flow along the TR-BRUSHY CREEK. With a storage capacity of 396 acre-feet and a normal storage of 63 acre-feet, the dam also serves purposes such as fire protection, stock, small fish pond, and recreation.

Managed by the Texas Commission on Environmental Quality (TCEQ), Cedar Creek WS SCS Site 3 Dam is inspected every 5 years and was last assessed to be in fair condition in June 2018. The dam features an uncontrolled spillway with a width of 64 feet and outlet gates including a slide gate and two uncontrolled gates. Despite its moderate risk assessment level, the dam has no Emergency Action Plan (EAP) in place, signaling room for improvement in emergency preparedness and risk management measures.

While the dam's hazard potential and emergency response protocols may require enhancement, Cedar Creek WS SCS Site 3 Dam stands as a vital infrastructure for flood risk reduction in the region. With its strategic location and design elements, this dam continues to play a critical role in water resource management and climate resilience efforts in Rockwall, Texas.

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.
