About Pointdexter Lake Dam
The primary purpose of Pointdexter Lake Dam is irrigation. The dam stores and diverts water for agricultural irrigation, supporting farming operations in the surrounding area. The dam is owned by Larry Pointdexter (private). It impounds the Tr-little Loutre Creek near Mineola.
The dam stands 30 feet tall, creates a reservoir covering 11 acres, has a maximum storage capacity of 177 acre-feet, and collects water from a drainage area of 28 square miles. Completed in 1975, the structure is well into its service life at over 50 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.
