ALLEGAN COUNTY (WKZO) -- Illinois officials have announced they plan to poison the water in another two mile stretch of the embattled Chicago Shipping Canal in two weeks to determine if there are any Asian Carp in that stretch of the waterway.

They will be closing that stretch of the canal for five days, as part of a 80-million dollar federal program designed to stop the northern migration of the invasive species.

But even that brief closure is drawing fire from business and shipping interests who don’t want any disruption in commerce. They will be using rotenone, which kills fish but doesn’t harm humans.

The Michigan DNRE will be closing a one mile stretch of the Kalamazoo River so they can dredge a poison out of the body of water. It’s the next phase of the dredging operations to remove PCB’s from the river sediment and the river banks. The closure, from 16th Street to the City of Plainwell takes effect immediately. They hope to complete the work in December.
