About Navarro Mills Dam
The primary purpose of Navarro Mills 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 Usace - Fort Worth District (federal). It impounds the Richland Creek near Richland.
The dam stands 87 feet tall and stretches 7,570 feet across, creates a reservoir covering 5,070 acres, has a maximum storage capacity of 323,879 acre-feet, and collects water from a drainage area of 320 square miles. Completed in 1963, 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. An emergency action plan is in place for this dam. The most recent inspection on record was 05/25/2022.
