Updated map: Lake Winnebago in eastern Wisconsin at Oshkosh, Lake Michigan, Lake St. Clair at Warren, Lake Erie and Lake Ontario (all highlighted with red in above map) have had metric tons of fresh water fish die from lethal viral hemorrhagic septicemia in 2005 through 2006; first die-offs of 2007 have now been reported to USGS. Authorities are trying to keep the virus from spreading to the other Great Lakes and into the Mississippi River (red underlined lower left) that extends south to New Orleans.
