Water Advisory in Place for Chippewa Lake

Children, pregnant or nursing women, individuals with certain medical conditions, and pets should avoid water contact at Chippewa Lake due to an algal bloom.

Test results from a water sample taken June 8 indicate toxin levels of 10.5 parts per billion, which is above the Ohio Department of Health threshold of 6 ppb recommended for posting a public health advisory.

The toxins are a result of algal blooms that occur in bodies of water due to a combination of factors including water temperature, rainfall, and nutrient runoff within the watershed. The Chippewa Lake algal bloom is the result of a microscopic organism called cyanobacteria. Its blooms can produce harmful toxins that may make people and pets sick when they come into contact with the water.

The park district will continue to monitor the lake. The advisory remains in effect until two consecutive tests taken at least a week apart show levels have fallen below the 6 ppb threshold. Should toxin levels exceed 20 ppb, the lake will be closed per Ohio Department of Health guidelines.

Notices have been posted at the beaches in the villages of Gloria Glens and Chippewa Lake and at the public boat launch ramp. The park district notified the mayor’s office in each village of the advisory, as well as the Medina County Health Department. Notices also have been posted on the park district’s Web site and social media pages.

Medina County Park District acquired the approximately 330-acre lake in 2007.
