If you can get the
boat to Tulsa, or Muskogee Oklahoma, you can take the McClellan–Kerr Arkansas River
Navigation System to the
Mississippi. The McClellan–Kerr Arkansas River
Navigation System is well maintained, and there is even a guide for boaters. I took it from Muskogee to Little Rock in a
Hunter 26, and the channel was well marked and 8+ feet deep at all times. I would do it all the way to the Gulf if I had the time.
