A new study released in April finds Asian carp may in fact be reaching the Great Lakes. The Asian carp is an invasive species with an appetite large enough to potentially decimate the food chain ecosystem of the Great Lakes. There have been many efforts to contain the spread of the fish in the Chicago Area Waterway System to connects to Lake Michigan. The study now raises new questions about the effectiveness of that system.
A federal study of 18 potential aquatic links between the Great Lakes and Mississippi River watersheds says none of them are likely pathways to the lakes for Asian carp.
Two members of Congress say an electric barrier system near Chicago meant to prevent Asian carp from reaching the Great Lakes had a 13-minute power outage.
