About Koenig Dam
The primary purpose of Koenig Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by F Stanley Koenig (private). It impounds the Crow Creek near Matson.
The dam stands 32 feet tall, creates a reservoir covering 9 acres, has a maximum storage capacity of 154 acre-feet, and collects water from a drainage area of 142 square miles. Completed in 1910, 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. The most recent inspection on record was 09/03/1978. That was 47 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
At 32 feet, this dam is taller than 76% of dams nationwide.
