About Klostergaard
The primary purpose of Klostergaard 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 Leland Klostergaard (private). It impounds the Tr-vermillion River.
The dam stands 28 feet tall and stretches 250 feet across, creates a reservoir covering 8 acres, has a maximum storage capacity of 100 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 1967, the structure is well into its service life at over 50 years old.
This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in loss of life. The most recent inspection on record was 11/12/1979. That was over 46 years ago.
