ISABELLA COUNTY, Mich. (WPBN/WGTU)– Flooding in Isabella County temporarily caused untreated sewage to overflow into the Chippewa River.

The Central Michigan District Health Department says as of Saturday morning, the wastewater treatment plant has been able to treat all incoming sewage before it is released into the Chippewa River.

Central Michigan Health Department and City of Mount Pleasant officials continue to urge citizens to avoid any contact with the Chippewa River until further notice. Activities to avoid include swimming, boating, fishing, kayaking and any activities which include physical contact with the Chippewa River and the flooded areas around the Chippewa River.

Testing will be conducted next week on the Chippewa River after flood waters recede to make sure that the presence of E-coli is at safe levels for partial and full body contact.
