The U.S. Army Corps of Engineers has released a report years in the making about options for keeping Asian carp from invading the Great Lakes.

The report given to Congress on Monday focuses on the Chicago Area Waterway System. The system is a network of rivers and canals that provides a direct link between Lake Michigan and the Mississippi River.

The report offers eight plans for preventing Asian carp and other species from migrating between the Great Lakes and the Mississippi basin.

Some options involve placing physical barriers in the waterways to separate the watersheds. The report estimates that physical separation could cost as much as $18.4 billion and take 25 years to complete.

Other potential steps include use of locks, electric barriers and water treatment to remove invasive species.

You can't stop these things IMO with any of the methods they are considering- they'll eventually make it to the lake. You can dig a pond and leave it alone- come back in five years and you'll have fish in it. Eggs get carried in by birds, or somebody dumps a bait bucket and- voila! They need to pour their research dollars into finding a method similar to how they got the lamprey problem in the lake taken care of- a poison- reactive only to that species. In this day of genetics they should be able to find something unique to this fish that they can then manufacture a killing agent from. It used to be that nearly every fish you pulled from the lake had lamprey marks- I hardly see them anymore. It was effective and lasting- and didn't do harm to anything else in the lake- that's the answer.
