Yes. For one option, the range is about $4.5 billion, and at the high end it is about $9.5 billion. So Mr. Donnelly, we're talking about a substantial cost to the United States should they decide to re-establish that natural disconnect between the Great Lakes and Mississippi basin.
Nobody is under any illusions that if you are to recreate a separation, which by the way is really the only way you can be sure these fish are not going to swim their way into the Great Lakes.... If they decide to move forward with that connection, we're not under any illusions; it's going to be a very costly endeavour to do so.
