I'm still a little confused, but since I have only a few minutes left, I'll let it go. It does strike me as a distinction without a difference.
Mr. Burden, you have a map attached to your presentation. What caught my attention was the two pink sections showing diverted drainage.
I understand what diverted drainage means in principle, but does that mean the drainage shown in these particular pink sections is diverted into the Great Lakes or away from the Great Lakes? What does that mean?
