South Spring Creek Lake

About South Spring Creek Lake

The primary purpose of South Spring Creek Lake is irrigation. The dam stores and diverts water for agricultural irrigation, supporting farming operations in the surrounding area. The dam is owned by Silver Spur Ranches C/o Colton Miller (private). It impounds the South Spring Creek near Saratoga.

The dam stands 33 feet tall and stretches 537 feet across, creates a reservoir covering 34 acres, has a maximum storage capacity of 856 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1917, 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. 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 fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. An emergency action plan is in place for this dam. The most recent inspection on record was 08/02/2023.

At 33 feet, this dam is taller than 78% of dams nationwide.
