Robbi - I have a nimble 11' G. Loomis rod with a Shimano TR reel clamped on that you can use. It is almost like a fly rod - long and lean and limber. I think it is rated for 40# line, but when you get a big fish you may as well be using two 5 1/2' poles, because it bends just about double. It is great fun for salmon, but it didn't take long to quit using it for the sturgeon. It does catch fish, though! I refer to it as my Doom & GLoomis. No matter what - rethinking the adventure is not an option.
Raven Dave, whom I hope you met at the SBS, fishes his fly rods in the river all the time, using bait and his downrigger for salmon trolling, and casting bait for sturgeon. He has a blast, and the others on board are used to waiting for him when he hooks up. Shoot, he has one reel that's worth more than the last two dogs we had, and they weren't cheap.
Tim - I would guess you could find a spot there at Cathlamet. And after that, you could just motor on down to Warrenton for a couple months of sturgeon. Life on the river is good.
Larry - Man, you are one good Camp Director!
This is going to be cool!
