Recent heavy rains have resulted in sewage discharges into the Saginaw River in both Saginaw and Bay City.
The discharge in Bay City is being reported as a partially treated combination overflow of sanitary sewage and rainwater. Saginaw city officials say their overflow into the river came from a retention basin following an estimated nearly two inches of rain falling over a 30 hour period.
More rain or a combination of rain and snow showers is expected to fall until early Tuesday. Total sewage discharge volumes are expected to be released once the precipitation ends.
