Morphy Lake Dam

About Morphy Lake Dam

The primary purpose of Morphy Lake Dam is irrigation. The dam stores and diverts water for agricultural irrigation, supporting farming operations in the surrounding area. The dam is owned by Acequia De La Isla & Acequia De La San Jose (local government). It impounds the Rio Morphy-tr near Ledoux.

The dam stands 27 feet tall and stretches 436 feet across, creates a reservoir covering 28 acres, has a storage capacity of 507 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 1940, the structure is well-established, with more than 75 years of service.

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 poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. An emergency action plan is in place for this dam. The most recent inspection on record was 06/15/2018. That was 7 years ago, which is on the longer end for a high-hazard structure.
