About Mohawk Dam
The primary purpose of Mohawk Dam is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by Usace - Huntington District (federal). It impounds the Walhonding River near Warsaw.
The dam stands 111 feet tall and stretches 2,330 feet across, has a maximum storage capacity of 285,000 acre-feet, and collects water from a drainage area of 1,504 square miles. Completed in 1937, the structure is well-established, with more than 75 years of service.
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. An emergency action plan is in place for this dam. The most recent inspection on record was 09/04/2020.
At 111 feet, this dam is taller than 98% of all dams in the United States.
