About Upper Serenity Dam

The primary purpose of Upper Serenity Dam is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by Lake Windcrest Poa (private). It impounds the Tr-dry Creek near The Woodlands.

The dam stands 10 feet tall and stretches 850 feet across, creates a reservoir covering 12 acres, has a maximum storage capacity of 121 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 1998, the structure is 28 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. Its condition is rated fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. An emergency action plan is in place for this dam. The most recent inspection on record was 11/07/2022.
