Asian carp have invaded the United States, with silver and bighead populations infesting Mississippi River basin waters as far north as the edge of the Lake Michigan basin in Illinois, and the Lake Erie basin in Indiana. An Asian carp invasion to the Great Lakes will clearly impact both U.S. and Canadian waters, but with established populations only in the U.S., efforts are focused on prevention primarily in the Chicago area.
