Current overflow sites are listed by waterway and location.
Due to heavy or prolonged wet weather activity, a portion(s) of the City of Toledo's combined sanitary and storm sewer collection system and existing underground storage facilities can reach capacity. A Combined Sewer Overflow (CSO) can occur in one or more locations within Swan Creek, Ottawa River and/or the Maumee River where the City is permitted to discharge during wet weather. The general public is advised to avoid these waterways for up to 48 hours after a combined sewer overflow event. For more information please contact: #419-727-2600.
Multiple CSO locations may be relieved simultaneously or at different times during wet weather events. The City of Toledo does not provide details of CSO activities until fully investigated after the conclusion of the wet weather event.
Details regarding wet weather overflows will be available here within seven (7) days of the conclusion of the event.
