Ensuring the safety and integrity of dams across Texas is a critical responsibility of the Texas Commission on Environmental Quality (TCEQ), which utilizes the TCEQ-20361 Dam Inspection Form as a comprehensive tool for this purpose. This detailed form serves as a standard for inspectors to evaluate various structural aspects and safety features of dams, including the conditions of embankments, spillways (both service and emergency), outlet structures, and potential hazard conditions downstream, to name a few. Items such as the dam's crest level, ground moisture conditions, and the general health of the embankment are meticulously checked to ensure the dam's ability to perform its functions safely. Furthermore, the form assesses security issues, operational procedures, communication systems, emergency action plans, and the presence and state of early warning and backup power systems. Ranking repair items by priority highlights the importance of addressing the most critical maintenance needs promptly to mitigate risks. The completion of this form not only facilitates a systematic inspection process but also plays a pivotal role in safeguarding the environment and populations living in proximity to these significant water retention structures.
