Liguori Lake Dam - Nonane 255

About Liguori Lake Dam - Nonane 255

The primary purpose of Liguori Lake Dam - Nonane 255 is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Redemptorist Fathers (private). It impounds the Tributary To Glaize Creek near Barnhart.

The dam stands 25 feet tall, creates a reservoir covering 3 acres, has a maximum storage capacity of 40 acre-feet, and collects water from a drainage area of 115 square miles. Completed in 1950, 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. The most recent inspection on record was 08/28/1978. That was 47 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
