When all else fails, I tie in a popper. Find some deeper water - a cut with shallow, grassy flats on each side or potholes that have sand bottoms and grass growing all around them. Work the popper along the edges of the grass. The trick is to chug the popper hard and FAST. If you work it like in freshwater you won't get a strike. You have you really rip it. If you see a boil under it, don't stop, like you would in freshwater, but chug it even faster. The popper should almost be skipping out of the water. Try this very early and late in the day when the light is low and hang on to your rod.
