Milwaukee Riverkeeper, along with countless other environmental groups have been demanding that immediate action be taken against the invasive Asian Carp, which can grow to over 100 pounds and wreak havoc on our Great Lakes' ecosystem.

Milwaukee Riverkeeper is demanding immediate closure of navigational locks that separate Chicago rivers from Lake Michigan.

Wisconsin has signed on with other Great Lakes States to force Chicago to do just that. The court case, filed against the Army Corps of Engineers and the Metropolitan Water Reclamation District of Greater Chicago, will force the locks closed except in emergency situations.
