Results of three consecutive years (1980 to 1982) of juvenile steelhead population monitoring in the Morice River system is presented in this report. Results are focused on late summer fish habitat descriptions, fish population estimates and annual survival rates within individual streams. Emphasis was placed on Owen and Lamprey Creeks, with lesser effort on other tributaries and mainstem areas. Estimated steelhead fry populations in Lamprey Creek ranged from 45,000 to 70,000. The 1+ population ranged from 17,000 to 30,000 while the 2+ population ranged from 1100 to 5400. Three year old parr were found only in 1982. Estimated survival rates range from 25 to 68% fry to 1+, and 6.6 to 18% 1+ to 2+. Total steelhead biomass was relatively constant, ranging from 214 to 239 kg. Estimates of Owen Creek steelhead population ranged from 38,000 to 100,000 fry, 19,000 to 31,000 yearlings, and 3000 to 6300 two-year olds. No 3+ parr were found. Survival rates ranged from 29.6 to 81% fry to 1+, and 9.6 to 33.7 % 1+ to 2+ p
