The escapement of adult steelhead Oncorhynchus mykiss to Sitkoh Creek in 1993 was counted at a weir located about 0.5 km upstream of the mouth of the creek. Five hundred and twenty fish were counted from April 10 to June 1; the mid-point of the immigration occurred on May 1, 1993. The 1993 escapement was 37% less than the mean weir counts of 1936, 1937, 1982, and 1990. All 520 steelhead were sexed, and 183 were randomly sampled for lengths and ages. Of the randomly subsampled fish, 64% were females which averaged 777 mm long (SE = 6.4 mm); males constituted 36% of the subsample and averaged 759 mm long (SE = 12.7 mm). The total escapement (520 steelhead) was composed of 63% female and 37% male. First-time spawners constituted 53% of the sampled escapement, repeat spawners constituted 45%, and 2% were unreadable. Fifty-eight percent of the nine complete age classes (i.e., freshwater age not regenerated) of repeat spawners were ages 3.2S1 (33%) and 4.2S1 (25%). Between May 11 and June 1, 1993 (when the weir was dismantled) a total of 332 steelhead kelts passed downstream through the Sitkoh Creek weir. An on-site creel survey estimated a total 342 angler-hours (SE = 82) to have been expended at Sitkoh Creek between April 19 and May 31; an estimated 84 steelhead (SE = 22) were caught and released (Sitkoh Creek was closed to harvest in 1993).
