Habitat

Habitat favorable to salmonids may be at odds with aesthetics.

Salmon habitat change
Recent change is evident in this upstream view within a major Sockeye and Coho salmon spawning reach in Power Creek near Cordova, Alaska. Former streambead on the partially snow-covered left side is about 1 meter higher than the water level. The stream has migrated to the right enveloping large spruce and hemlock trees. The remains of one tree that was deposited on the elevated former stream during a rain event is visible in the background.
