Yes, you're absolutely correct. The Army Corps of Engineers is currently studying how to keep Asian carp out of the Great Lakes. They have identified seven options for doing so. There's a range that includes things like non-structural measures all the way up to complete separation between the Great Lakes. There are two ways of doing that. One, as I said, would cost $15.5 billion and the other would cost $18.4 billion and would take about 25 years to complete. Currently they're doing consultation and looking at which option is the best to move forward with.
So you're right, and it's my understanding as well, that the shipping industry is not happy with the option of complete barrier separation, but a lot of groups do believe that's the only thing that will work in order to permanently address this problem.
