Results indicate that 1985 was a good year for steelhead fry recruitment. Of 11 major areas sampled, 7 were ranked the highest ever sampled (or tied); 4 ranked in the middle. Of the most important areas (e.g., Bulkley and Morice mainstem and major tributaries, such as Upper Bulkley, Lamprey, Owen, Canyon, and Telkwa, 6 and 7 ranked No. 1.

The fact that fry populations were higher throughout the system sug
