Observations
Species Date Observed Activity
coho salmon 10/09/2024 Rearing Present

Comments: Coho smolt captured in two minnow traps in Canyon Lake, within lake and near outlet. Lake residents had constructed a dam at outlet, but water was visibly flowing underneath dam. Dam does not appear to be a passage barrier for adult salmon due to the presence of coho smolt within the lake but could be a barrier to juvenile fish. Two traps were set in the lake body, approximately 10 m apart. One trap (61.894510, -151.614834) captured 12 coho, and the other (61.894532, -151.614982) captured 7 coho and 1 three-spine stickleback. In total, 19 juvenile coho were captured.
