Trout Lake

About Trout Lake

The primary purpose of Trout Lake is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Chase Mutual, Inc. (private). It impounds the Appenzell Creek.

The dam stands 24 feet tall and stretches 390 feet across, creates a reservoir covering 96 acres, has a maximum storage capacity of 1,117 acre-feet, and collects water from a drainage area of 3 square miles. Completed in 1900, 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 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 01/11/2021.
