The U.S. Court of Appeals in Chicago has upheld a lower court ruling dismissing a lawsuit filed by five states seeking the placement of barriers to keep Asian carp from invading the Great Lakes.
An estimated 180,000 cubic yards of contaminated sediment is scheduled to be removed from the Indiana Harbor and Canal starting in April.
Placing dam-like structures in Chicago waterways would be an almost foolproof method of preventing Asian carp from reaching Lake Michigan, while a less pricey electric barrier system also has solid prospects for shielding the Great Lakes from the invasive fish.
IDOT hopes to have some final issues resolved with the U.S. Fish and Wildlife Service, state and federal environmental protection agencies and the U.S. Army Corps of Engineers by the end of this month.
The U.S. Army Corps of Engineers’ plan would involve building levees, restoring some lands to their natural states as marshes or prairies, as well as flood-proofing some homes.
In a new report, the U.S. Army Corps of Engineers said, if Chicago doesn’t get some significant rain or snow soon, there could be serious water flow issues in the Chicago River.
Some Great Lakes States are putting pressure on the federal government to wall off the Chicago Sanitary and Ship Canal to stop the spread of Asian carp.
