Word from that summit that there could be a shift in a long-standing dispute over invasive species in the Great Lakes region. Addressing a gathering of Great Lakes governors, Illinois' Pat Quinn said he's willing to consider placing barriers in Chicago-area waterways to keep Asian carp from reaching the Great Lakes. Quinn said separating the lakes from the Mississippi River watershed is the "ultimate solution". Michigan and four other states sued - Wisconsin, Minnesota, Ohio and Pennsyvania -- unsuccessfully, trying to force permanent barriers to keep the carp away from the lakes' multi-billion dollar fishing industries. Indiana has contended that such a re-engineering of Chicago rivers and canals would disrupt commerce and cause flooding, and Indiana Governor Mike Pence says his position, opposition to separation, has not changed.
