I have caught them alot .there are some big ones in there if you look for them ..I usually hit one while fishing for something else then I switch over ..
I use a super ultra light setup for them .I have noticed I catch 5 - 1 over the other friends using stronger poles ..If they feel the rod they're gone .. fish like you would for walleye ..(shh I have caught a couple of them in lake wash too, as well as a sturgen and a lake trout ,sturgen almost killed me as I use a small boat. and have also had fish robbed by sea lions out in the lake ) I was planning another trip to kapowsin soon . with the sockeye thing lake washington is a no go for a few ...If you wanna hook up and go for perch let me know ..still trying to find a good crappie hole on lake washington too ..
