About Soldiers Meadow Dam

The primary purpose of Soldiers Meadow 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 Webb Creek near Sweetwater.

The dam stands 69 feet tall and stretches 535 feet across, creates a reservoir covering 150 acres, has a maximum storage capacity of 3,195 acre-feet, and collects water from a drainage area of 6 square miles. Completed in 1922, the structure is over a century 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.
