About Short Creek Southside #1

The primary purpose of Short Creek Southside #1 is irrigation. The dam stores and diverts water for agricultural irrigation, supporting farming operations in the surrounding area. The dam is owned by United Effort Plan Trust (private). It impounds the Offstream near Colorado City.

The dam stands 38 feet tall and stretches 1,195 feet across, creates a reservoir covering 9 acres, has a maximum storage capacity of 84 acre-feet, and collects water from a drainage area of 10 square miles. Completed in 1975, 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 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 05/02/2024.

At 38 feet, this dam is taller than 85% of dams nationwide.
