TRAVERSE CITY, Mich. (AP) – Activists and ordinary citizens in northern Michigan say a federal plan for keeping Asian carp out of the Great Lakes would take too long to carry out. The U.S. Army Corps of Engineers is hosting public meetings on a report it issued this month with eight alternatives for preventing the carp and other invasive species from moving between Lake Michigan and the Mississippi River watershed in the Chicago area. They range from doing nothing new to spending more than $18 billion over 25 years erecting barriers that would seal off the two watersheds from each other. During a meeting Thursday in Traverse City, a stream of speakers supported physical separation but insisted it should be done faster than 25 years. They said the corps should show more urgency.
