This is a water clover. It is actually an aquatic fern. Although there are native Marsilea in North America this is an introduced invasive from Europe. When it is well established it can cover large areas of shallow water. It is easily identified by its glabrous leaves. It is showing up in more places in the south. Fortunately, it seems to like man-made lakes instead of the natural environment. For more information: plants.usda.gov/java/profile?symbol=MAQU
