Even if, in the most unfortunate circumstance, Asian carp do move into, for example, Lake Michigan at first, we have to ask ourselves which one is potentially next and even more expensive from a societal point of view.
Again, on the topic of prevention of Asian carp, we'd invite you, as your study progresses, to invite representatives of the Great Lakes cities initiative, the Great Lakes commission, who, to their credit, invested several million dollars in a very good engineering study that has clearly shown the feasibility of physical separation of those two basins.
Is it expensive? Yes. But they've shown that it can be accomplished, and accomplished in a way that would not only prevent aquatic invasive species but would provide benefits to other segments of the economy, not only benefits to recreational fishing and commercial fishing but benefits to how goods are transported through that Chicago shipping canal system—and flood water control, for that matter.
