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. The U.S. Army Corps of Engineers released the study Friday. It's among reports the agency is producing as it develops recommendations for preventing Asian carp and other invasive species from crossing between the two watersheds.
Experts say the easiest way for Asian carp to attack the lakes is through a navigational canal near Chicago that helps connect the Mississippi River with Lake Michigan.
But the study analyzed 18 ditches, marshes and other spots along the aquatic boundary that could form links, especially during flooding. None posed a high risk as Asian carp passageways. Three posed a medium risk.
