What do you think is making the large car tire size beds, 8 or 10 touching each other. They just started showing up about 4 years ago in select areas, now they are every where.i haven't seen any fish on them. Same pattern as bluegill only 10 time larger. Usually smooth clean sand bottoms. No black, no shells,
I see bluegill beds, some crappie beds, some largemouth beds, but I don't have a clue on what these are
