I would try to find a feeder creek or river with some deeper holes like 16-18 foot. This gives the fish a refuge as water levels increase or when salinity rises. In the wintertime they should be in these spots relating to structure. Other times of the year they may roam around the other shallower areas in search of food. Old oxbows or sleighs can be good especially early morning. Learning to cast and vertical jig structure would be a plus, but you should be able to tightline (spider rig). When fishing a freshwater species in tidal waters always consider the lower tide better than the higher. This is opposite of saltwater species, but high tide brings in more salt. Though, the fish will bite better when water is moving one way or the other with either type water or species you fish. I hope this helps.
