MASON CITY, Iowa – The Department of Natural Resources says the flow of Mason City sewage into the Winnebago River has stopped.
City officials reported the discharge ended at 8 pm Monday. After the collapse of a sewer line on Friday, the city pumped untreated wastewater into a storm sewer than emptied into the river near the Norris Youth Softball Complex on 2nd Street NE.
The DNR says children and pets should still be kept away from riverbanks near the discharge for another 24 hours.
A review of this situation and what the DNR calls “appropriate enforcement action” is being planned.
