I used to float Barren river every year, we put in at the 101 bridge and took out either 4 to 7 miles downstream at the old iron bridge. Yes muskys are in that river, we had a couple blow up on top waters and one followed the bait all the way back to the boat,he looked like jaws coming up at that little bait, ultra lite and 6 lb test is not a musky rig. To answer slowjams ?. the river has lots of bass, we caught several up to 5 lbs, smallies in spots, and spoted bass,bluegill,hybrids,cats, carp,white bass. It has been a while since I have floated it but is is a ggod river to fish. Also the area below the dam is a good muskey spot this time of year, the feeder creek down below the camp ground is a good spot. Good luck
