Nickelson, T. E., J. D. Rodgers et. al.  1992.  Seasonal changes in
habitat use by juvenile coho salmon (Oncorhynchus kisutch ) in Oregon
coastal streams. Can. J. Fish. Aquat. Sci. 49:4 783-789.

Abstract- Habitat use by juvenile coho salmon (Oncorhynchus kisutch )
during spring, summer, and winter was examined in Oregon coastal streams.
Coho salmon fry were most abundant in backwater pools during spring.
During summer, juvenile coho salmon were more abundant in pools of all
types then they were in glides or riffles. During winter, juvenile coho
salmon were most abundant in alcoves and beaver ponds. Because of the
apparent strong preference for alcove and beaver pond habitat during
winter and rarity of that habitat in coastal streams, we concluded that
if spawning escapement is adequate, the production of wild coho salmon
smolts in most coho salmon spawning streams on the Oregon Coast is
probably limited by the availability of adequate winter habitat.
