3.2.3 Coho Salmon
A summary of coho salmon stock status is presented in Table 10 and escapement data are included
in Appendix I. Of the 129 known coho stocks, 10.1% (n=13) are identified as unthreatened, 8.5%
(n=11) are identified as of some concern and 76 % (n=98) are identified as potentially threatened.
Eight of the top 11 coho producing streams (based on historical average escapement) are threatened
(Kingkown Inlet System, Lowe Inlet System, Quitonsta Creek, Eagle Creek, End Hill Creek,
Clifford Creek, Salmon Creek and Stannard Creek) and these streams all have current escapements
less than 16% of their historical means. On the other hand, both the Khutzeymateen and Ecstall
rivers are unthreatened and mean escapements in the 1990s were 265% and 401% of the historical
mean escapement. Even so, some of the notable coho stocks are in apparent decline and include:
• Clifford Creek, at 0% of its historical mean escapement
• Salmon Creek, at 0% of its historical mean escapement
• Georgie River, at 0% of its historical mean escapement
• Eagle Creek, at 1% of its historical mean escapement
• Kingkown Inlet System, at 3% of its historical mean escapement
• Stannard Creek, at 7% of its historical mean escapement
• End Hill Creek, at 9% of its historical mean escapement
