About Kjerstad No.1

The primary purpose of Kjerstad No.1 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 Nathan Kjerstad (private). It impounds the Bad River-tr.

The dam stands 22 feet tall and stretches 525 feet across, creates a reservoir covering 18 acres, has a maximum storage capacity of 263 acre-feet, and collects water from a drainage area of 5 square miles. Completed in 1960, the structure is well into its service life at over 50 years 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 fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. An emergency action plan is in place for this dam. The most recent inspection on record was 12/19/2023.
