The Army Corps of Engineers is proposing a plan to stop silver and bighead carp moving from the Mississippi River basin into the Great Lakes.

Cheryl Nenn with Milwaukee Riverkeeper calls the proposal a starting point, not a solution, because multiple aquatic invasive species are threatening both the Great Lakes and the Mississippi River basin.

The U.S. Army Corps of Engineers is responsible for breakwaters around the country, including the Great Lakes.  

The structures calm the waters within them to allow ships and smaller vessels to navigate safely, but take quite a beating, given shifting lake levels and seasonal storms.   

The usual "fix" is to install big boulders, 6 to 10-feet in size, to reinforce failing stretches of breakwater.
