Middle Fork Reservoir Dam

About Middle Fork Reservoir Dam

The primary purpose of Middle Fork Reservoir 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 Indiana-american Water Co Inc (private). It impounds the Unnamed Tributary Middle Fork East Fork Whitewater River.

The dam stands 74 feet tall and stretches 3,257 feet across, creates a reservoir covering 174 acres, has a maximum storage capacity of 12,000 acre-feet, and collects water from a drainage area of 47 square miles. Completed in 1963, 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 09/04/2019.

At 74 feet, this dam is taller than 97% of all dams in the United States.
