(AP) The Iowa Department of Natural Resources has found that hog manure discharged over a farm field caused a Mitchell County fish kill earlier this week.
The DNR reported Friday that Anders Knudsen, of Saint Ansgar, pumped 25,000 gallons of waste from a hog nursery building to a nearby field. The manure then ran over the field and into Otter Creek, causing a fish kill along almost four miles of stream about a half mile south of the Minnesota state line.
The majority of the more than 150,000 fish killed on Monday were minnows, shiners, chubs, dace and other small species. The kill also claimed more than 200 sunfish and around 20 smallmouth bass. The DNR says it will seek $34,408.50 in restitution for the fish killed.
