Altiers Lake Dam

About Altiers Lake Dam

The primary purpose of Altiers Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Cherry Miesse (private). It impounds the Sunday Creek near Rendville.

The dam stands 19 feet tall and stretches 285 feet across, creates a reservoir covering 5 acres, has a maximum storage capacity of 70 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 1949, 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. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 04/13/2022.
