Fraser system sounds like the most likely candidate....

Fall fishing for large Harrison river Kings is good from mid September to mid October. These fish head up the Fraser river before entering the Harrison near Chilliwack, BC and are very good biters and wicked fighters. These are the 'White' Kings and although their reputation for eating is not the same as a red King, their scrapping ability is superior. Harrison river Chinooks are larger and average 30 lbs with many fish over 50 and 60 lbs taken!
