Description: As part of a continuing stock assessment program in Southeast Alaska, the Division of Sport Fish obtained indices of escapement for chinook salmon Oncorhynchus tshawytscha in designated streams and transboundary rivers. The estimated total escapement in 1998 was 65,353 large (age .3 and older) chinook, a 64% decrease from the escapement of 179,968 fish estimated in 1997. The 1998 estimate was 152% of the 19751980 base period average of 42,437 chinook salmon, 103% of the 19811985 average of 62,591 and 72% of the 19861990 average of 89,249. The estimated total was the lowest since 1984. Eight out of eleven escapement indices declined from 1997; however, indices exceeded goals in the Alsek, Situk, Chilkat, Unuk, and King Salmon rivers and Andrew Creek, and were near goal in the Stikine River. Escapement to Chickamin River increased from 1997 but remained below goal.
