Missouri River, start to finish

Has anyone ever canoed the Missouri, starting in Yellowstone, and ending at the Gulf of Mexico. Assumption would be that there would be whitewater in Yellowstone through Montana. Please help. Is there an on-line journal or a book available to help me?

There is a guy currently doing it in a kayak for parkinsons. I forget the site but he’s got a SPOT locator and is doing it now. Search google kayak parkinsons and you should find it.
