Hi All
1st let me say that my experience fishing some locally and on some OP rivers is that low-clear water and Coho are not a good mix. They tend to be more aggressive when they are 1st moving into the river and then once they are in there for a while, they go closed mouthed. Once the rains come and we get some color and the fish start moving, those same fish are more apt to bite. I've also witnessed on numerous occasions guys getting Solduc Coho early in the morning, releasing nice fish because they didn't want to quit and then once the sun is up, it just Turns-Off and they are kicking themselves for not keeping the fish they had caught.
One other theory to throw out there is where did thses hatchery fish come from. What river/race. I had a conversation with a Hatchery Manager a few years ago about why it seems like the Wind River fish that friends were getting were more aggressive then Solduc Hatchery Springers. He went into a 5 minute explanation that the Wind River fish came from X river and they were more aggressive and that the Solduc fish came from Y river (I can't remember the names) and they were known for not being an aggressive fish. Not sure how accurate this is but that is how it was explained to me.
WIth rains comming this week it is going to be interesting to see how everyone does on all these fish in the system. I bet the once the rivers color a little the posts are going to change
