Summary

This earth dam, with a height of 28 feet and length of 1267 feet, serves to protect the surrounding area from potential flooding from the TR-SOAP CREEK. With a normal storage capacity of 90 acre-feet and a maximum storage of 727 acre-feet, this dam plays a vital role in managing water resources in the region.

Owned by the local government and regulated by the Texas Commission on Environmental Quality (TCEQ), the dam is designed to withstand high-risk situations, although its hazard potential and condition assessment are currently not available. The absence of a spillway and limited outlet gates indicate the dam's reliance on its structural integrity to manage water flow effectively. Despite its age, the Mountain Creek WS SCS Site 11 Dam continues to fulfill its primary purpose of flood risk reduction, highlighting the importance of proper infrastructure in safeguarding communities against climate-related risks.

For water resource and climate enthusiasts, the Mountain Creek WS SCS Site 11 Dam serves as a fascinating case study in the intersection of infrastructure, water management, and environmental protection. As the region's landscape and climate evolve, the ongoing maintenance and monitoring of this dam will be crucial in ensuring its continued effectiveness in mitigating flood risks and preserving the ecological balance of the area. With its historical significance and practical impact on local water resources, this dam stands as a testament to the importance of sustainable engineering solutions in confronting the challenges of a changing climate.

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.
