Great Lakes invasion threat
Asian carp gets all the press, but there are 40 other species swimming in the Chicago River that could spring an unwanted invasion into the Great Lakes. So says a new report by the U.S. Army Corps of Engineers, as relayed by the Milwaukee Journal-Sentinel’s Dan Egan. At issue is whether the Army Corps should build an electric barrier to separate the Chicago River from Lake Michigan. Many environmentalists say the barrier should be built now, but the Army Corp is still in studying/evaluation mode.
