I believe that there is no ice: too much current. Everything will be scouted anyway.
Paul, the Rouge was the 2nd river I ran in my (short) paddling carreer (1st was the Jacques-Cartier). The Ottawa and Gatineau came later. I see no reason why you could not run it in you new boat! Great opportunity to try it, and believe me: in a Super Hero, the Rouge at 80 m3/s won't even flip you, it's definitely a playboat level!
