Much of the press and media attention on the growing Asian carp threat has been focused on the Chicago canal and Lake Michigan. But that is not the only potential entryway for the invasive fish to enter the Great Lakes. 
 
“At the top of that list of secondary pathways is an area in northern Indiana called Eagle Marsh, which separates the Mississippi basin’s Wabash River from the Maumee River basin that feeds Lake Erie. The two watersheds have a history of merging in extreme rains, so to reduce the threat of carp making the jump into Lake Erie, the federal government has erected a fence between them.”
Read the complete article linked above for more information about other potential pathways that Asian carp might take.
