About Perry City Dam - Lower
The primary purpose of Perry City Dam - Lower is water supply. The dam stores water for municipal, industrial, or agricultural use, helping ensure a reliable supply for the surrounding area. The dam is owned by City Of Perry (local government). It impounds the Mace Branch Lick Creek near Perry.
The dam stands 26 feet tall, creates a reservoir covering 16 acres, has a maximum storage capacity of 223 acre-feet, and collects water from a drainage area of 1,583 square miles. Completed in 1964, 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 09/30/1978. That was 47 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
