Your best bet would be to invest in a guide. I know it's not always cheap, but the experience is well worth it. Your chances of hooking fish, are better than even finding fish by yourself. I am sure there are exceptions to this, but I am talking about the majority of people.

I am sure the Lewis will pick up as the days go on. I don't think they got much of a springer run this year, but should get a good summer run. I know the river level is up early, and they drop it down as the months go on. So you can expect sled traffic down low. I've never fished the Lewis, but will someday. I think Stlhd1 might know how to fish the Lewis, he might even be able to squeeze you in.

Anyways good luck, and save some for the rest of us.
