About Homestake Project

The primary purpose of Homestake Project is water supply. The dam stores water for municipal, industrial, or agricultural use, helping ensure a reliable supply for the surrounding area. The dam is owned by Homestake Project (tom Hankins) (local government). It impounds the Middle Fork Homestake near Minturn.

The dam stands 265 feet tall and stretches 1,996 feet across, creates a reservoir covering 333 acres, has a maximum storage capacity of 45,500 acre-feet, and collects water from a drainage area of 7 square miles. Completed in 1967, 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. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 08/17/2022.

At 265 feet, this dam is taller than 99% of all dams in the United States.
