Yes, we have to respect these rivers. I generally wear my inflatable PFD when I fish the Salmon River (flows into Lake Ontario). It is not unusual for a fisherman to drown there during the Fall-Winter salmon season. There have been times that I have locked my elbow with my young nephew to traverse some areas of the Salmon River. Now that I am 70 plus, I have discovered that I'm not as quick on my feet as I would like to be.
