I was on the lower river a couple weeks ago during a pulse, and it was quite confounding. Now keep in mind that this time of year fishing is generally more difficult on the Clinch (but my favorite time to be on that water). However, there was absolutely zero activity, and I threw everything I had in my box with no results. Was surrounded by carp (or buffalo) almost everywhere I went, which makes me wonder if the water temps were a little too warm.
I would focus my efforts on the upper river where the temps should be a little more reasonable.
