Thanks Dave, I've read through those but I've found many places where rivers have both a center line and a stream back imported from government data. I guess the real question is do administrative boundaries extend to the bank or the center of a river. I'm gathering that the answer is "maybe" because each case could be different and I'd need to find the actual document containing the survey in order to know for sure.
Thanks so much to everyone responding to this thread. I have a much better understanding of these cases now!
