Hinckley Lake Dam Rehabilitation
Project Updates
(October 2024) Construction is ongoing at the spillway. Please be mindful of posted signs at construction entrances with intersections of the APT and keep an eye out for entering and exiting construction traffic. Concrete work at the spillway is ongoing with a few final pours for the spillway crest in the coming weeks. Grading activities along the West portion of the earthen dam are ongoing. Tree clearing for the 2025 dredging work will take place in the coming weeks. Tree clearing will result in temporary closures of West Drive and the APT. Please follow posted signs for closures during working hours.
As the continued reminder, for the safety of our visitors, access to the lake is strictly prohibited for the duration of the project.

About
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 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 remains open throughout the project but access to Hinckley Lake will is prohibited until the project is complete. Staging for the project is occurring at several locations throughout the park including Buzzard Roost. The dam rehabilitation is expected to cost approximately $9-10 million.
