Mind you, the Navionics HotMaps Premium West card has more inland details for the rivers and lakes. (See my JPG attachments to this post, I've made sample images.) The Navionics 2XG is primarily coastal content and is mostly Canada with just a good dash of USA content by the borders. But that 2XG card does indeed have the Columbia River and Willamette in reasonable detail for navigational purposes.
Depending on your needs you might want the Navionics 1XG USA for all the coastal content (very good for USA west coast) AND the HotMaps West for the inland rivers and lakes. It's hard to find one card that has everything you want in one super-card.
