I guess my reservation is that we did set loading targets, we met them, and the concentrations fell to where we thought they needed to fall, yet we still have the problems locally. I am uncertain in my own mind to what extent those problems are because of the changing food web in the Great Lakes and the different pathway the phosphorus is following, and to what extent it is because of diffuse pollution that we haven't dealt with yet.
Certainly for western Lake Erie, there's no doubt in anybody's mind that we have to control phosphorus to solve that problem, but for other parts of the Great Lakes, such as Lake Huron, I'm not so sure this would help the problem.
