The Alexander County lake has major problems with siltation . During the Great Flood of 1993 the river tried to shift back to the Horseshoe Lake meander , but returned to its modern channel after the flood subsided . Much of the lake resembles a swamp or bayou . This is one of the northernmost parts of the natural ranges of the Bald cypress and Tupelo trees , which are found on the shoreline of the lake . Another tree found here is the swamp cottonwood . There is a good growth of the flowering American lotus
