G'Day Wayne,I live in Petawawa and have fished the Ottawa from Rapids de Joachim, pronounced de swisha all the way down to the damn below Campbells bay. These waters are not known for ski's in any great numbers. But there are some. The area you are talking about below the rapids down river from Pembroke to the rapids above Chapeau Qc I have never fished. That is the nastiest section of the river for navigating. Theres to many suprises waiting, for me to take my bassboat in there. But I can tell you that the walleye fishing as well as sm and lm, and northerns is really good. The fishing pressure below the rapids from Pembroke all the way down past Campbells Bay Qc is very light, mostly worm dunkers and bass fisherman. I have a buddy who fishes the area you are talking about in his beat up tinny, I will give him a call and see if there is skis in that area for you. Hey Leechman lets hook up next season and do some largie fishing down the Lapasse way. Thats my favorite area for them hawgs.
