Don't the planes normally do the drop off over by the LLC Ranger Station?  I wouldn't assume they'll drop him off near Bell Island/Twin Falls... and my guess is that is why DentonDoc asked the question.  If it IS at the Ranger Station, then John has a substantial paddle on big old LLC to reach Bell Island. If it's me looking at that stretch, I'm seriously considering arranging a tow across the lake with either Zup's or Ed Ottertail (if you're brave & if he is even still in business... which is mostly problematic, year-to-year, based upon the condition of his boat). Anyway, LLC is big and can be pretty nasty when that breeze gets blowing.  John needs to ask where they are setting him down.

Jim J, I'm not sure I'd be terribly concerned about Deux Rivieres that early in the year (2nd week of June), although I'll allow that it CAN be the case if the snow melt isn't all that much.  Later in the year, however, Deux Rivieres is definitely more problematic, of course.  Jim J's advice to "have a Plan B" is sound.  Always best to check with park officials (or recent trip reports here on QJ) just before paddling into that area.  However, I'd almost be more concerned about the front end of the trip with the flow of the Maligne coming AT me.  In a big snow melt year, it can be somewhat challenging near some of the portages.  Again, check w/park officials or w/QJ trip reports.

7 nights/8 days for a couple guys in decent shape in their 20's?  I foresee see much of an issue, other than the two already mentioned... which, most of the time, won't be issues.  You probably even have a couple "layover days" to spare.  Of course, John would need to arrange pick up at a pre-appointed time in Stanton but that is likely included with whatever package deal he got from the fly-in service.  John, on the oddball chance that you were planning to do a DIY & leave a car in Stanton, just be advised that - unless you have Canadian license plates - you can't do it.

Sounds like a nice route for that time of year.  Don't cut yourself too short on your last day of paddling, however.  If I'm you, I'm camping on the north side of Pickerel on the last night.  Have been caught having to cross that body of water on the last day &, believe me, it ain't any fun when the wind gets to howling out of the west/northwest!

John, use the QJ PCD resource to plot out probable campsites en route.  If you have interest in fishing for specific species, let us know what they are & some of the veterans here can IM you with some suggestions re: fishing holes.  As you might expect, that information can be tough to come by via public posts.

Just a few thoughts from the peanut gallery.
