The entire state of Tennessee only has one natural lake so I really never fish anything BUT current . Even the cow ponds have some flow here! Fish tend to face upstream and wait on food to come their way. I don’t like for them to see me, so I usually cast upriver if I’m wading shallow water. If im floating downstream in shallow water I like to cast downstream (most consider this sacrilegious) or directly across, trying to get the bait to a fish that hasn’t yet seen me. Deep current, like the TN river, the fish usually can’t see me, especially the ones on the bottom. When it’s raging fast they tuck up against the bank or behind rock shelves. When it’s slower they spread out and get a little tricky but still eat.
