OK! It's done! Four of us are booked into Lac Roz for the second week in June. Lac Roz is about 100 km north of the Transtaiga road that runs E/W across the James Bay region, serving Hydro Quebec and the La Grande river system of generating stations. We will fly from Montreal to LG-4 airport in a PC-12 Pilatus, about 1000 km, and then take a float plane from there, about 150 km, to the lake. The camp has hot and cold running water, shower, propane stove and fridge. Food is provided for us, along with 21 ft Vercheres river boats and new 20 hp four strokes. The targets are lake and speckled trout, and there are pike as well. Just 80 more sleeps!
I think BigCreekDad has been up that way with MIrage Outfitters almost 10 years ago, and maybe Fishnsled? Has anyone else fished Roz?
Thanks again, joeytier, for your great advice. Perseverance paid off!
