Coho salmon (Oncorhynchus kisutch) utilization of tributary lakes and streams in the Keogh River drainage, British Columbia / by N.T. Johnston, J.R. Irvine, and C.J. Perrin.: Fs97-4/1973E-PDF

"Salmonid utilization of tributary lakes and streams in the Misty Lake and Long Lake sub-drainages of the Keogh River, British Columbia was studied between November 1985 and April 1987. About 30-45 adult coho spawned below Misty Lake, but adult fish were not found above the lake. Juvenile rainbow trout migrated up Misty Outlet stream in November after the first freshet, but juvenile coho did not show directional movement in the fall. Neither adults nor juveniles moved upstream in Misty Inlet stream. Coho fry migrated upstream towards Misty Lake and Long Lake soon after emergence, and reared in the lakes and tributary streams throughout the summer and winter. Smolts migrated downstream in mid-May at a size of about 95-100 mm fork length. We believe that small tributaries and lakes are important rearing habitats for juvenile coho and overwintering habitats for rainbow trout"--Abstract, page iv.
