Description: As part of a continuing stock assessment program for chinook salmon Oncorhynchus tshawytscha in Southeast Alaska, the Division of Sport Fish obtained indices of their escapement in designated streams and transboundary rivers. The estimated total escapement in 1994 was 77,156 large (age .3+) chinook, a 27% decrease from the record high of 106,286 fish in 1993. The 1994 estimate was more than twice the 19751980 base period average of 32,701 chinook salmon, 163% of the 19811985 average of 47,187, and 121% of the 19861990 average of 63,606. Escapement indices exceeded management goals in the Stikine River (though down 44% from 1993), the Situk River (up 57% from 1993), and in Andrew Creek (down 46% from 1993). Indices were below goal in the Alsek River (though up 15% from 1993). The King Salmon River index count decreased from 280 fish in 1993 to 224 in 1994 (down 20%). Indices in three of the Behm Canal systems remained below management goals: Unuk: (down 38% from 1993 ), Chickamin (no change), and Blossom rivers (down 47%), while the Keta River (down 15%) was at goal.
