Uh, no. The water is really, really low. You'll walk more than you float.

And if the river was running? That's white water kayaking, and not for anyone without experience.

I would never even consider for a second taking an inflatable on any white water anything - that sounds like suicidal thinking. You want something that survives contact with sharp points on rocks. The Sur would be a wild ride and you would have a heck of a time portaging around the hundreds of fallen trees making strainers in the river.
