Michigan has committed eight-million dollars to help keep Asian carp from using the Des Plaines River to swim into Lake Michigan.
The money will be used to help design a more effective barrier at the Brandon Road Lock and Dam, located 27 miles southwest of Chicago.
Recent tests have revealed increasing amounts of Asian carp DNA in waters downstream from Brandon Road. No live carp have yet been found.
A project to beef up the barrier at Brandon Dam is awaiting federal approval.
Asian carp can grow to as large as 100 pounds. When frightened, they can jump as high as 10 feet out of the water.
Officials fear that they could ruin the existing Great Lakes fishery if they can work their way into the lakes.
