If you and your family are looking to take a dip in Lake Erie and cool off this holiday weekend, you may want to avoid these ten beaches.

The Ohio Department of Health has issued bacterial contamination alerts for Lakeshore Park and Geneva State Park in Ashtabula County.

A bacterial contamination warning is issued when the level of E. coli bacteria in the water has reached unsafe levels and could make you sick. Children, the elderly, and people with ailing health or weakened immune systems are advised not to swim.

E. coli are bacteria that occur in many places, such as the intestines of humans and animals.

Other Lake Erie beaches currently under bacterial contamination warnings include:

Bay Park Beach, Clifton Beach, Columbia Park Beach.

Darby Creek, Cranberry Creek, Pickerel Creek, Bay View West

Kelley’s Island State Park

The Department of Health sometimes issues a recreational health alert when algal toxins have been detected in levels that are hazardous to health. The Department of Health recommends avoiding all contact with the water, including swimming and wading. Pets should be kept away from the water.

There are currently no public health warnings in place for beaches on Lake Erie in Ohio.

Warnings remain posted until a follow-up water sample shows bacteria levels below the recreational limit.
