Barnettm, most people anchor or beach their boat on the Snohomish. A few people troll some sections, but I've almost never seen anyone boondog or pull plugs.

It may or may not be obvious, but the river hazards change a lot based on flow. Right now, it is almost 9000 cfs or about 4 ft on the gage height. That extra 2 ft from a flow of 3000 cfs is a huge difference. Needless to say, if the flow is down aroud 1000 it is basically 0 on the gage or 4 ft less deep! If you stay on step, it is not impossible, but harder to hang up at the higher flows. You still have to know when you can come off step.

Finally, you might want to consider hiring a guide to give you some pointers when you want to learn a new river. I'm sure Three Rivers can hook you up in that respect, and may be worth the piece of mind.
