Abstract: A creel census was conducted in 1979 and 1982 on the upper St. Mary River in southeastern BC to examine angler effort and catch distribution within one watershed, and to analyze the size and age structure of cutthroat trout prior to and following a 2.5 year angling closure. In July and August 1979, prior to the closure, total effort for the two months was estimated at 5000 angler hours resulting in a harvest of 4000 fish (0.71 fish/hr). Catch composition was 96% cutthroat trout, 2% Dolly Varden and 2% mountain whitefish. Following the re-opening of the fishery on August 31, 1982, in September and October, total effort for the two months was estimated at 2170 angler hours to harvest 1710 fish (0.79 fish/hr). Catch composition was 79% cutthroat, 13% Dolly Varden and 8% whitefish. Catch success rates and the proportion of the catch released before and after the closure were similar. However, the spatial distribution of anglers and catch within the watershed and the size and age composition of cutthroat trout in
