I found on the lake I fished, that during the summer heat, Smallies would come shallow to feed, but keeping deep water close by. When the water is warm the lake I fished Smallies would keep deep water close to where they would feed shallow. Deep water meaning first available weed line. 12-15 feet of water. I also observed that unlike largies, who go under logs and docks and boats to get outta the sun, Smallies tend to seek a little deeper water for shade/cool. Now I know this isn’t true everywhere. But was very much in play on the last lake I fished.
