If you take the bay that is on the eastside of steamboat, and come over to the falls(about where the entrance is to Steamboat park) , which is right in the corner almost, you can take your boat UNDER the hi-way via a passage or bridge and actually have your boat in that mud pool you see in the picture. I wouldn't necessarily do it when its muddy as you can't see the rocks below, but it is deep enough, and actually a great place to pick up some bluegill and even some perch and crappie in there.
