With a structural height of 34 feet and a length of 1816 feet, this dam provides a critical storage capacity of 2462 acre-feet, serving as a crucial element in the region's water resource management system. The dam's spillway, with a width of 103 feet, ensures controlled water release during peak flow periods, safeguarding downstream areas from potential inundation.
Managed by local government authorities and regulated by the Texas Commission on Environmental Quality (TCEQ), the dam has a fair condition assessment as of April 2021, indicating its operational reliability. Despite being uncontrolled, the dam's spillway design and outlet gates, including a slide gate and two uncontrolled outlets, facilitate efficient water discharge mechanisms. The dam's moderate risk assessment level suggests the need for ongoing monitoring and risk management measures to ensure continued safety and functionality, in line with its flood risk reduction purpose. For water resource and climate enthusiasts, Mountain Creek WS SCS Site 9 Dam stands as a testament to effective engineering for sustainable water management in the region.
