A second consecutive year of juvenile steelhead life history data was collected on the Morice River system in August 1981. Sampling was conducted at 33 sites throughout the Morice system with emphasis on Owen and Lamprey Creek. Estimated standing crop (total biomass) of juvenile steelhead in Lamprey Creek was similar in 1980 and 1981, while estimated population number (0+, 1+ and 2+ age groups) was much higher in 1981. Owen Creek standing crop and estimated population were both much higher in 1981. Estimated survival from 1980 fry to 1981 yearlings was 68% in Lamprey Creek and 81% in Owen Creek. Data from other areas in the Morice system, including Houston Tommy Creek, Gosnell Creek, Shea Creek, Thautil River and the Morice River is also reported.
