The chinook salmon (Oncorhynchus tshawytscha) escapements to the Skeena River have declined from 1950 to 1973 (Figure 1). In 1973, restrictions on sport and commercial fisheries were implemented to aid in recovery of Skeena River chinook stocks. Investigations of major chinook spawning grounds were undertaken in 1975 to procure information useful in the design of a more intensive management program. The objectives of this report were to determine: 1) Numbers, distribution and timing of chinook spawners in the Bear-Sustut, Morice and Lower Babine rivers. 2) Suspended solids and water temperatures during spawning in the above three systems. 3) Rearing potential for young chinook in the three systems.
