Transplant coming to waters near Portland

Hi all, my name is Omar.  I'm already a kayak fisherman and have a Malibu Stealth 12 right now.  It's been a great rig for the ocean fishing I've been doing.  I'm relocating to the Portland area this summer (Milwaukie) and I'm wondering if this yak will be good for the rivers there or if I should be looking to sell this and purchase a different kayak.  Any input will be greatly appreciated.  Due to proximity I'd expect the Willamette, Columbia, Tualatin and Clackamas rivers will be where I spend most of my water time.

If it matters I have mostly fished using bait caster/spinning setups but am working on my fly casting as well.  thanks.
