Purple Sage Ranch Lake Dam

About Purple Sage Ranch Lake Dam

The primary purpose of Purple Sage Ranch Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Champion Domain Llc (private). It impounds the Tr-medina River.

The dam stands 25 feet tall and stretches 1,430 feet across, creates a reservoir covering 34 acres, has a maximum storage capacity of 342 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 1947, 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. An emergency action plan is in place for this dam. The most recent inspection on record was 01/31/2019. That was 7 years ago, which is on the longer end for a high-hazard structure.
