Report Summary: Among the several Skeena River tributaries that harbour summer/ Fall runs of steelhead trout (Salmo gairdneri Richardson), the Zymoetz-Clore system ranks as one of the most important in terms of angler use. Located near the major urban centers of North-Coastal British Columbia (Terrace, Kitimat, and Prince Rupert), the Zymoetz-Clore sport fishery has sustained considerable angling pressure over the past two or three decades without displaying, until recently, any apparent sign of decline or collapse (Steelhead Harvest Analysis 1970-78). However, two major flood events in 1974 and 1978, plus concomitant construction and reconstruction of a natural gas pipeline adjacent to and in some places within the river channel, expanding logging activity, and continued commercial gillnetting at the mouth of the Skeena have contributed to a recent, marked decline in angler success. The Fish and Wildlife Branch, being aware of the importance of this fishery to residents of the Lower Skeena area, and concerned about steelhead population declines attributable to both habitat loss and over-exploitation, has placed a high priority on the assessment and enhancement of Zymoetz-Clore steelhead stocks. Habitat inventories have been compiled by Truelson and Varney (M.S. 1975) and Humphries and Morley (M.S. 1978). The latter also presented an outline of potential enhancementworks in the upper Zymoetz (McDonell Lake) area. Ptolemy (M.S.
1979) intensively and critically inventoried and assessed biological conditions (and production limiting factors) within the steelhead spawning area located immediately below McDonell Lake. Chudyk (M.S. 1979) reported on the diversion of Serb Creek, a major constraint to steelhead enhancement in the McDonell Lake area. This paper presents data collected during a creel census conducted in the years 1978 and 1979, and includes information on angler harvest and success, and life histories of Zymoetz-Clore steelhead. Funding was made available via the Salmonid Enhancement Program.
