Construction of the dam started in 1926 and was built with the purpose to block water from the Rocky River to hold back enough to fill a 100-acre lake.
Starting September 18, 2023, Hinckley Lake will close for dam rehabilitation. It will begin with the temporary draining of the lake. The project requires that the lake remain drained until the dam rehabilitation is completed which is expected by Summer 2026 based on current schedule and funding. The dam will turn 100 years old in 2027. Find out more information on the Hinckley Dam Rehabilitation project.
