Mgreeti,

Thanks for the feedback! I have also searched the web and all what I found was about warm water fishing in the inland lakes. It seems that there is a good pike and walleye fishing up there. However, I was more interested in fishing for brook trouts in the inland creeks. I only found that the NP website mention something like... "in some creeks there are also brook trouts" I was wondering in which creeks are trout and if it is worthy to carry the rod with me. It'll be several days of backpacking.... and I don't want to carry any extra weight.
Regarding to the water purifier, yes, we are prepare for that. Thanks, again for the tips
