About Kinnippi Lake Dam

The primary purpose of Kinnippi Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Hubbard&donald (private). It impounds the Tr To Dry Creek near Desoto.

The dam stands 27 feet tall, creates a reservoir covering 10 acres, has a maximum storage capacity of 144 acre-feet, and collects water from a drainage area of 100 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. The most recent inspection on record was 03/04/1981. That was 45 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
