The Lower Holston is fishing very well in the early AM up until about 2pm. By then the sun is at peak and the bite slows considerably. Get out there by 7 or 8am and focus on the cut banks and weed beds. There's lots of grass right now because of the months of sun and little rain. The fish are densely packed in feeding lanes but will regularly take a medium bodied dark popper fished with a slow chug. It's a long float so just fish the high spots after 2pm and take a lunch break a little later so you can fish the prime water.
