In the Ozarks we have many, many streams that are excellent for floating with either a canoe or kayak. An excellent reference for finding floatable streams in Missouri is the Paddler’s Guide to Missouri, produced by the Missouri Dept of Conservation. It is now out of print but I’ve been told they’re producing an updated version. In the meantime you can find most of the same information in an online version of the Paddler’s Guide to Missouri. Similarly detailed information on Arkansas Rivers can be found at the Southwest Paddler’s website.
