Lantana Regional Detention Dam

About Lantana Regional Detention Dam

Lantana Regional Detention Dam is a dam in Travis, Texas. The dam is owned by Lantana Place Llc;lantana Southwest Hoa Inc (private). It impounds the Tributary Williamson Creek.

The dam stands 28 feet tall and stretches 825 feet across, and has a maximum storage capacity of 189 acre-feet. Completed in 1996, the structure is 30 years old.

This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 11/01/2017. That was 8 years ago, which is on the longer end for a high-hazard structure.
