Hinckley Lake Dam Rehabilitation
Construction at the spillway is underway. Please be mindful of posted signs at construction entrances with intersections of the All Purpose Trail and keep an eye out for entering and exiting construction traffic. The contractor has installed their erosion control features and established construction haul routes. The contractor is currently working to establish their control of water plan. For the safety of our visitors, access to the lake will be strictly prohibited during the lowering process as well as the construction project duration.

This project includes the rehabilitation of Hinckley Dam in the Park District's Hinckley Reservation. The dam, which was completed in 1927, has provided recreation and helped mitigate flooding for nearly a century and created the 87-acre manmade Hinckley Lake. Over the next several years, the rehabilitation project will improve the recreational opportunities Hinckley Lake, raise the height of the existing earthen dam embankment that stretches across the northern portion of the lake and rehabilitate the 150-foot-wide concrete spillway to meet modern standards and provide improved protection in the event of severe flooding.
Over the last century, the Rocky River has deposited a significant amount of silt in Hinckley Lake, which varies in depths from 2-16 feet. Concurrently with the dam rehabilitation, Cleveland Metroparks will remove excess silt deposits in specific areas of the lake to allow for proper depths for recreation.The lake will remain open throughout the spring and summer of 2023 including for watercraft rentals at the Hinckley Lake Boathouse & Store, swimming at the Hinckley Spillway and the return of the Ledges-to-Lake Adventure Race on September 16.
Following summer activities, on Sept. 18, 2023, the dam rehabilitation will begin with the temporary draining of Hinckley 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. Hinckley Reservation will remain open throughout the project but access to Hinckley Lake will be prohibited once the project commences. Staging for the project will occur at several locations throughout the park including Buzzard Roost. The dam rehabilitation is expected to cost approximately $9-10 million.
