As has already been pointed out, there are walleye in the columbia. But for the pike family the nearest I believe is probably Lake Merwin in Washington for tiger muskie. I believe there are a few other lakes Washington stocks/stocked with tiger muskie I just can't recall what ones.
Oh, cool to see there are people that have been to MN or know someone that has lived here. I like MN, its where I was born and probably where Im gonna die. I would still like to go west of here to do some trout fishing though Ive always wanted to fish near the mountains somewhere. aaaaaaaahhhh, its just relaxing thinking about it.
Northern Pike, Walleye...trade you some Pike Minnows and Tui Chubs.
I drool like Homer Simpson every time I watch one of those fishing shows from your neck of the woods, I'm a Rain-not snow kinda guy.
Your Winters are way to long and cold, we get chilly and wet.
