TOWN OF HUMBOLDT (WLUK) -- About 100,000 gallons of manure has spilled into a stream in eastern Brown County, the state Department of Natural Resources says.

The spill happened at the James Kroll farm on Finger Road (Hwy. V) in the Town of Humboldt. The DNR says the spill happened sometime on Monday when an employee left a valve open. The farm originally reported the spill as about 1,000 gallons and began cleanup on Tuesday. However, when the DNR got on scene, it discovered that the spill was much larger and needed more berms, sumps and pumping to be cleaned up. The spill has since been contained.

Crews determined that the manure flowed into a stream for about 3.5 miles to the Luxemburg Road crossing, where the stream is known as School Creek. School Creek is a tributary of the Kewaunee River.

DNR experts are investigating the extent of impacts to water quality. Right now, the DNR warns that water in the stream may not be safe for people or pets. Because of the area's geology, the DNR says groundwater could also be affected. Private well owners should monitor their water and report any changes in color or odor to the DNR or county health department.

The Kroll farm is not a concentrated animal feeding operation, or CAFO, and does not operate under a DNR permit.
