About Cedarville Dam

The primary purpose of Cedarville Dam 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 Fort Wayne - Utilities Engineering (public utility). It impounds the St. Joseph River.

The dam stands 27 feet tall and stretches 1,900 feet across, creates a reservoir covering 460 acres, has a maximum storage capacity of 7,830 acre-feet, and collects water from a drainage area of 763 square miles. Completed in 1953, 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. Its condition is rated fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. An emergency action plan is in place for this dam. The most recent inspection on record was 10/23/2018. That was 7 years ago, which is on the longer end for a high-hazard structure.

The Indiana dam safety program can provide more specific information about emergency planning for this structure.
