Federal officials are hosting two meetings in Michigan this week to discuss options for preventing Asian carp from reaching Lake Michigan through waterways in the Chicago area.
The U.S. Army Corps of Engineers released a report this month with eight alternative plans for stopping migration of the voracious carp and other invasive species between the Great Lakes and Mississippi River watersheds.
The most expensive proposals would place structures, such as dams in Chicago rivers and canals, to seal off aquatic links between the two systems. They're estimated to cost $15-18 billion and would take 25 years to complete.
Public meetings to explain and gather feedback on the report will be held Tuesday in Ann Arbor and Thursday in Traverse City. They're among seven meetings being held across the region
