Asian Carp Invading the Great Lakes

Asian carp jumping out of the Illinois River near Havana, IL

Invasive Asian Carp have been detected only six miles from Lake Michigan in the Chicago Sanitary and Ship Canal, past an electric barrier designed to keep them out of the Great Lakes. The Asian Carp Rapid Response Workgroup completed operations in late November 2009 involving intensive fishing and a major rotenone application to kill all fish in a six mile stretch of the Chicago Sanitary and Ship Canal in an effort locate and halt the spread of the carp invasion.

This was a drastic measure, taken because much is at stake if Asian carp are able to reach and populate Lake Michigan and the Great Lakes. But we can’t let this drastic event become an ongoing management measure. Nor can we allow this manmade gateway between the Great Lakes and the Mississippi River Basin to remain open and available as a conduit for further invasion to both basins. While the current threat is from invasive Asian carp to Lake Michigan, we shouldn’t lose sight of the threat posed to Illinois rivers and streams from this connection; this was the pathway for invasion of the zebra mussels into much of the eastern half of the United States. We must call on the State of Illinois and the Army Corps of Engineers to act immediately to close all connections between the Chicago Sanitary and Ship Canal, adjacent waterways including the Des Plaines River and the I&M Cnanal, and Lake Michigan. Take action here!
