Y T Ranch

About Y T Ranch

The primary purpose of Y T Ranch is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Laramie Energy Llc (private). It impounds the Grove Creek near Collbran.

The dam stands 35 feet tall and stretches 900 feet across, creates a reservoir covering 12 acres, has a maximum storage capacity of 193 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1911, 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 unsatisfactory, indicating serious safety deficiencies exist that require immediate attention or remedial action. An emergency action plan is in place for this dam. The most recent inspection on record was 05/26/2022.

At 35 feet, this dam is taller than 82% of dams nationwide.
