Summer at Winton Woods just hit a snag. Great Parks of Hamilton County pulled the plug on all water-based recreation at Winton Lake on Friday after routine testing turned up elevated E. coli levels and staff tracked the problem to an active sewage leak near Winton Woods Harbor. Paddleboarding, fishing, kayaking, and canoeing are all on hold while crews flush and repair a damaged pipe, although the rest of Winton Woods Park is still open for land-only visitors.
Park officials said they shut things down after consulting Hamilton County Public Health and the Metropolitan Sewer District of Greater Cincinnati, and they notified the Ohio EPA as a standard step in situations like this, according to FOX19. Signs around the lake now urge visitors to wash their hands and avoid swallowing lake water, and temporary handwashing stations have been set up near the shoreline, the statement said.
Expo Activities And Park Operations
The timing is rough for the Kids Outdoor Adventure Expo. Organizers shut down fishing and other water attractions for the event on Saturday, but they kept the ziplining, rock climbing wall, golf instruction, archery, and the scheduled 5K, 10K, and Kids Adventure Dash up and running, as reported by WLWT. Swimming in Winton Lake is already prohibited under Great Parks bylaws, and the rest of the park remains open for business.
Health Risks And Precautions
E. coli and other bacteria from sewage can trigger gastrointestinal illness and skin infections if contaminated water is swallowed or comes into contact with broken skin, according to CDC guidance. Hamilton County Public Health advises people to steer clear of contaminated water, wash their hands after visiting the park, and follow posted warnings. The department monitors sanitary sewer overflows and issues guidance after spills.
Not The First Time
Winton Lake has been through this before. The lake has seen previous closures in recent years when sewage or high bacteria levels were detected, and it reopened after testing and remediation in May 2025, in coverage that noted the lake welcomes back visitors post sewage spill. Coverage from WCPO and others shows that park staff, the Metropolitan Sewer District, and public health officials have coordinated responses to stop discharges and retest the water before reopening.
How Long Will The Closure Last?
For now, there is no set timeline for when boats and boards will be allowed back on the water. Great Parks says it is actively working to flush and repair the damaged pipe and will post updates and alerts on its website. For official notices, visitors are urged to check GreatParks.org for sample results and safety guidance, and to follow any additional instructions from Hamilton County Public Health.
