The beautiful autumn we've been having is definitely causing trouble for the salmon in the smaller tributaries...
...in reviewing the tributary to the larger creek, no salmon are able to move upstream beyond the first riffles, effectively restricting the coho in shallow pools.
This physically restricts the normal breeding patterns of coho: mates restricted, spawning site selection limited, spawning and redd progression restricted.
This is a very large pair, the larger coho is ~3' long.

Today in ~> the Creek ... Coho Waiting for Rain
reblogged from QuestX
The water levels have definitely dropped since Sunday.
The water in the main creek is no longer high enough to allow for fish passage over barriers and the water levels in the smaller creek have dropped enough that the fish are effectively trapped in short reaches, are restricted to moving downstream, or are at/ near the confluence of the tributary and main stem of the creek.
^Video of Coho moving downstream today, waiting for more rain.
