About Vega Dam
The primary purpose of Vega Dam is irrigation. The dam stores and diverts water for agricultural irrigation, supporting farming operations in the surrounding area. The dam is owned by Bureau Of Reclamation (federal). It impounds the Plateau Creek near Collbran.
The dam stands 162 feet tall and stretches 2,100 feet across, creates a reservoir covering 1,109 acres, has a maximum storage capacity of 38,102 acre-feet, and collects water from a drainage area of 24 square miles. Completed in 1959, 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.
