About Deam Lake Dam
Deam Lake Dam is a dam in Clark, Indiana. The dam is owned by Department Of Natural Resources (state). It impounds the Big Run Tr Muddy Fork.
The dam stands 59 feet tall and stretches 1,200 feet across, creates a reservoir covering 183 acres, has a maximum storage capacity of 9,971 acre-feet, and collects water from a drainage area of 3 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. 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 11/02/2017. That was 8 years ago, which is on the longer end for a high-hazard structure.
