I did the Chilko, Chicotin and Fraser down to Lillooet in August 1984. My recollections after 32 years and lots more river miles may be different than I would see it now. The Chilko is the real deal. My friend did it in his 14 ft bucket boat and his wife did nothing but bail. He was very afraid the whole way. We followed the next day on a guided trip in an 18 ft self bailing SOTAR. Much of the Chilko had large waves kind of like the Grand Canyon, but the gradient was much, much steeper. Unlike the Colorado, the Chilko is not pool drop and the rapids are much longer. We rejoined my friend at Hanceville on the Chilcotion. I rowed a 12 ft bucket boat with my wife as a passenger. I don't recall the rapids in Farwell Canyon as being very difficult and I was a very neophyte boater at the time. The Fraser has lots of big volume flatwater and no rapids until Lillooet. We portage at least one of the rapids just upstream of Lillooet after talking to the First Nations people who were fishing there.How much whitewater is there relative to say the Grand Canyon of the Colorado?
