I have an idea, seal off the canal and put in a ship transfer station on either side. Ships from Lake Michigan can dump loads on the lake side and barges can dump from the river side. Stuff can by transfered from the Mississippi to the Great Lakes without the carp getting through. This will create jobs and cost less money in the long run (goverment wants to spend millions to control the carp, why not stop them and spend a couple million once not every year.
