Update December 3rd 5:13 pm:
Marc Gaden of the Great Lakes Fishery Commission says "as far as I know, no one thinks there are any Asian Carp in Lake Erie." He says Lake Erie is colored red in the USGS map above because two Bighead carp were found in commercial fishman's nets several years ago. They colored the entire Lake red based on these two incidents.
