Haven't been to Bonneville lately, but that sounds like a good pic....Did try the St Helens area on Saturday, and Kelly Point the previous Tuesday.
I've been very dissappointed with the Colubmia bite, both before and after the nets went in. We limited in 4 hours the earlier day, but not on the Columbia; up the Willamette about a mile. Saturday, we fished from Trojan to the bottom of the slew. Didn't see or get anything more than a few shakers.
I'm not really sure why, but what little bite we've seen has been a really soft bite; fish pecking and nibbling, not really actively feeding. I wonder if the water temp is what's up..
