This is why getting a very detailed and comprehensive risk assessment is so important. We understand that Canada is doing some work on this right now, which we are eagerly awaiting. Actually, they're cooperating with the U.S. Geological Survey and the U.S. Fish and Wildlife Service.
I think the sense is, intuitively, that the Chicago Area Waterway System presents by far the largest risk, and because we can't deal with all 19 at once, the idea is to accelerate the process of finding and implementing a solution there. The U.S. Army Corps of Engineers is proceeding with its Great Lakes and Mississippi River interbasin study, but that's going to play out over some long period of time.
There has been some interim action taken in a place called Eagle Marsh, where the Wabash River, which comes up off the Ohio River and comes very close to the Maumee River, which goes out into Lake Erie at Toledo.... There's actually been installed not a full physical barrier, but a very tight mesh fence a mile or two long through this marsh, and they've actually seen carp, not Asian carp, up against that fence. But there are Asian carp in the Wabash River, and yes, they are up the Ohio River. As I mentioned before, they're all the way up into Minnesota on the Mississippi River and the Minnesota River and in the Wisconsin River.
Again, none of those potential contact points present anywhere near the level of risk that the Chicago waterway system does. We think it's important that the work go ahead on those, but we've really got to fast-track the Chicago waterway system.
