Yes. Just to make it unanimous, I don't think you have too many scientists who were cheering for the changes that we saw. Be that as it may, we need to echo those comments already made about fish habitat.
I have a little story. There's that little tributary that I showed you in my slide with respect to phosphorus. It turns out that it's one of the most important walleye runs and nursing habitats. It stops at what is a historical dam and it's obviously the end of the spawning run at that point. In terms of how much more extensive it was in previous years we can't say, but it shows the limitations when you start to encroach on habitat.
