Fish kill reported along Rock River

STERLING, Ill. (AP) -- Illinois investigators are trying to figure out what caused a fish kill on the Rock River in northwestern Illinois - between Grand Detour and Sterling.

Sgt. Carl Lewis of the Illinois Department of Natural Resources says they're trying to determine if the run off from a train derailment in the Rockford area got into the Kishaukee River, which flows into the Rock River. That train was carrying ethanol, and Friday's derailment caused an explosion that killed one person.

The Department of Natural Resources is working with the state Environmental Protection Agency and the Illinois Emergency Management Agency.

The state is advising the public not to eat fish from the Rock River in Ogle, Lee and Whiteside counties until the cause of the fish kill is determined.
