The Humber in Newfoundland can be crowded in many areas, especially around Big Falls. Light coloured bombers with orange hackle are very popular. The SPAWNER magazine each year has fly patterns for the Humber and other rivers. The website that Alan gave you has fly patterns indexed to back issues that you can order.
Paul Marriner's book "Modern Atlantic Salmon Flies" has many patterns by Rob Solo, one of the best authorities on the Humber River in Newfoundland.
