A dredge scoop from the muddy ditch bottom by Joel Wooster on 1/27/2006 tells the tale - three species [Corbicula fluminea (Müller, 1774) Asian Clam (A), Pomacea maculata Perry, 1810 (B), and Melanoides tuberculata (Müller, 1774) Red-rim Melania (C)] - all of them exotic invasive species. Conspicuous by their absence are the native Viviparus georgianus (I. Lea, 1834) Banded Mysterysnail that were found by the hundreds during October of 2005.
