About Fisher Peak Det. Fpc-1

The primary purpose of Fisher Peak Det. Fpc-1 is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by City of Trinidad Dpw (local government). It impounds the Purgatoire River-tr near Trinidad.

The dam stands 85 feet tall and stretches 540 feet across, creates a reservoir covering 12 acres, has a maximum storage capacity of 338 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1961, 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 10/24/2022.

At 85 feet, this dam is taller than 97% of all dams in the United States.
