Officials say broken main letting sewage into Little Sioux River

Untreated wastewater from a broken main is spilling into the Little Sioux River in northwest Iowa's Cherokee County.

The Iowa Natural Resources Department says the break was reported Monday morning by the town of Quimby. River flooding has kept repair crews from finding the break and fixing it.

The department says more than 15,000 gallons (56,780 liters) of untreated wastewater is flowing into the river each day.

Authorities project the river will remain above flood stage for several more days.
