About Colonial Acres Lake Dam
The primary purpose of Colonial Acres 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 Colonial Acres Inc (private). It impounds the Tyler Branch-cinque Hommes near Menfro.
The dam stands 29 feet tall, creates a reservoir covering 17 acres, has a maximum storage capacity of 264 acre-feet, and collects water from a drainage area of 352 square miles. Completed in 1965, 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. The most recent inspection on record was 09/27/1979. That was 46 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
