A fish kill has been reported along that stretch of the river, and the cause is unknown.

“There’s speculation that the runoff from the derailment in Rockford area of the ethanol got into the Kishwaukee River which flows into the Rock River,” Sgt. Carl Lewis of the Illinois Department of Natural Resources explained to WQAD-TV. “We won’t know until we get the water samples back and determine what is in the water.”

The IDNR is working with the Environmental Protection Agency and the Illinois Emergency Management Agency to investigate the matter.

The Department of Natural Resources advises against eating fish from that section of the river until the cause has been determined.
