Kjerstad Dam No. 2

About Kjerstad Dam No. 2

The primary purpose of Kjerstad Dam No. 2 is fire protection, stock, or small fish pond. The dam maintains a small impoundment used for fire suppression, livestock watering, or as a fish pond. The dam is owned by Leonard Kjerstad (private). It impounds the Bad River-tr.

The dam stands 14 feet tall and stretches 335 feet across, creates a reservoir covering 6 acres, has a maximum storage capacity of 57 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1941, 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 12/19/2023.
