About Coleman Dam

The primary purpose of Coleman Dam is irrigation. The dam stores and diverts water for agricultural irrigation, supporting farming operations in the surrounding area. The dam is owned by City Of Coleman (local government). It impounds the Jim Ned Creek near Coleman.

The dam stands 92 feet tall and stretches 4,700 feet across, creates a reservoir covering 1,886 acres, has a maximum storage capacity of 91,680 acre-feet, and collects water from a drainage area of 299 square miles. Completed in 1966, 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.
