Ok in Rhodey most of our lakes with the exception of South County are man made, they have dams, old river channels, rock formations, and so on. But in most of the lakes you can find groups of baitfish, whether it be groups of 20-40 sunny's roaming the shallows or groups of dozens of yellow or white perch in the coontail.
This even goes for our natural lakes, even though most are really choked up with grass, if you can find the edge of the grass you will see groups of baitfish roaming around. There are not exactly "schooling" or in "balls" but they are in large groups shall we say. As for natural lakes that dont have much grass or dont have lots of baitfish. I will just try to find rocks and fish them hard with a jig or tube. Its really simple but it gets the job done.
