I have found quite a few small mouth mid river in the deep channel behind boulders on the current seam picking off bait as it floats by. It would seem that some sort of moving bait with fast sinking capabilities would be the most effective way but I can’t really figure out which one possibly a deep crank or a heavy spinnerbait?
Or if you’re in the camp that firmly believes in extreme water temps (outside of 55-70 degrees) mature fish (18”+) will not chase and must be finessed, a Ned or a tube? Seems like a slow means of covering water but if they won’t hit a crank or a flashy moving bait or even a glide than perhaps a necessary evil.
The river I fish averages 4-6’ deep, 50-75 yards across. I typically float in a kayak.
