“The Ohio River is equally important,” Brown said.
During the call-in conference, Brown was asked about the wisdom of putting the U.S. Fish and Wildlife Service in charge of the effort — the agency approved importation of the fish in the 1970s as a way to clear deal with scum on southern ponds. Brown defended having the same agency head up the coordination effort, noting that “I think they are best equipped to do it and learn from their mistakes.”
Biologists have said that the carp pose an especially severe threat to Lake Erie because it is the most biologically diverse of the five Great Lakes. That is to say there’s plenty of grub for the carp to eat here.
While the species could come in the front door through the Chicago Shipping Canal and Great Lakes system, there is also a threat of access from the Ohio River. Long Lake in the Akron area, is near the Tuscarawas River, an Ohio River tributary. Flooding that area could create the link between the river and lake that would give carp access to Lake Erie, according to a 2010 U.S. Army Corps of Engineers study. Other likely gateways, according to the corps’ study, are Chicago and a flooded marsh in northern Indiana.
