According to a new report the best way to make sure the Asian Carp stays out of Lake Michigan: put up huge dams along waterways that empty into the lake. A number of different options were analyzed including installing electric barriers, shining bright lights in areas where the Carp are most.likely to swim and even set up sound systems that would make a lot of noise in hopes of keeping the fish away. However when all were considered, dam installation was determined to be the one that would be the most effective. The study was done in part by the U.S. Forest Service.

Shippers are concerned if attempts are made to actually close shipping locks it would have a devastating financial impact on their business. For example the Chicago Shipping and Sanitary Canal carries millions of tons of cargo every year.
