Check out the Dragover section on the Ouachita. You can hike your own shuttle. The river makes a huge bend that gives you about 5 miles of river to float, but it's only a 10 minute hike from put-in to take-out. Anything below Hwy 270 is floatable pretty much year around, though you might need to get out and let your kayak float through a spot or 2 if we don't get much rain in the next month. Please release any smallmouth you catch down there -- plenty of spotted bass, catfish, etc. if you're wanting to fry some up.
