Back in the mid 90's, my group paddled McIntyre creek, which flows from McIntyre into Robinson.  There is a 620 portage noted on the map, but back when we did it, we were able to paddle the whole thing.  By "paddle", I mean there was barely enough water to float the canoe, and we basically walked along side (we are wet foot canoists) and weaved our way through the tiny opening in the woods to get where we needed to go.  It was one of the neatest Quetico memories I have.  I've never been back since and am wondering if this is still possible today.  You can spare the caveat about water levels - obviously that is going to make a huge difference on this, but I'm wondering if we just got lucky that year or if McIntyre Creek is regularly paddleable, and if anyone has done it recently.
