Public Health Advisory Issued for Chippewa Lake

Earlier this month, the Ohio Environmental Protection Agency notified the park district that satellite imagery indicates the presence of an algal bloom in Chippewa Lake. Algal blooms occur 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. A water sample collected on May 3 showed toxin levels of 4.06 parts per billion. Test results received on May18 from samples taken on May 15 indicate toxin levels of 12.6 ppb.

Per Ohio’s Harmful Algal Bloom Response Strategy for Recreational Waters, a Recreational Public Health Advisory is issued when toxin levels reach 6 ppb. It warns children, pregnant or nursing women, individuals with certain medical conditions, and pets to avoid contact with the water. When toxin levels reach 20 ppb, an Elevated Recreational Public Health Advisory is issued, warning all persons and pets to avoid all contact with the water. The warnings remain in effect until two consecutive tests taken at least one week apart show levels have dropped below those thresholds. The park district will continue to monitor toxin levels as needed.

If toxin levels exceed 20 ppb, Chippewa Lake will remain open to boaters on an idle-speed, no-wake basis only. The warning for all persons to avoid all contact with the water -- including activities such as swimming, jet-skiing and water-skiing -- will remain in place.

Medina County Park District is partnering with Aqua Doc Lake and Pond Management, as well as with the Save the Lake Coalition and other area agencies, to collect data and research ways to address the algal bloom problem.

Movie to be filmed at Chippewa Lake

The public boat ramp at Chippewa Lake will be closed from 9 a.m. May 23 through 8 a.m. May 24 for filming of the movie “The Last Summer.” Additional filming will take place in and around the Chippewa Lake area through May 25. The schedule could change based on the weather. All boaters and residents are asked to keep their distance from crews as they are working to avoid interference with filming. The movie is scheduled for a 2019 release by California-based Gulfstream Pictures.
