The city of Cherokee found and repaired the break in a 16-inch wastewater forcemain this afternoon.
The city reported untreated wastewater discharging to a tributary of the Little Sioux River Friday morning shortly after discovering the break at 10:30 a.m.
The DNR recommends residents keep children and pets away from the area near 630 River Road for another 24 to 48 hours.
The river should be safe for kayaking and other recreational activities as wastewater disperses and moves downstream.
The DNR is onsite and will continue to monitor the cleanup. For more information, contact Tom Roos or Ken Hessenius at 712-262-4177 or Tom.Roos@dnr.iowa.gov.
