Yes. The U.S. Army Corps of Engineers is doing a risk assessment of all the physical connections between the Mississippi River and Great Lakes basin. It's a risk assessment that is a little different from what we undertook, because it is specifically looking at the risk of organisms moving through those connections between the basins. It's not looking necessarily at the impact, but simply at whether or not the organisms can move.
Based on their assessment, they will then prioritize actions to minimize that risk. In that assessment, the Chicago Area Waterway System came out as the highest risk. There was another waterway, Eagle Marsh, between the Maumee and Wabash rivers and the Lake Erie basin, where there is this huge wetland at the headwaters that connects the two. They have actually put up a fence to physically separate fish in the two basins to not allow the movement of adult carp.
I think they identified over 30 connections in all. After that one, the risks declined quite dramatically. There are not a lot of other risky connections, physical connections anyway.
The U.S. Army Corps of Engineers has been doing this intensive study of those connections.
