Advice on trip to St.. Regis area

Hello everyone, me and some buddies are looking at doing a canoeing/camping trip in early September. we are looking at staying 3 nights. Our plan as of now is to bust butt the first day get as far as we can,thinking "fish pond". then set up base camp then fish/explore from there for the remainder of the time. None of us are fly fisherman spinning tackle only. Any advice or info on the area would be greatly appreciated. Does anyone know what the portages are like in that area, from what I have seen on maps it looks like there is a small stream that connects most of the lakes through the area. Also how secluded is this area, should we expect to see other groups? And also what are the main fish species in the area? Thanks you
