Never seen an alligator in the Catawba River, but the local media has reported alligator sightings. I don't know of any congregation of alligators. Actually I have only seen two news reports in the last few years.
Check out Catawba Riverkeepers website. Tega Cay has had quite a few accidents with raw sewage dumps in the river, not residents fault but outside company that city has contract with. At one time there was a warning from DHEC we had high mercury levels in large mouth bass. But I don't eat fish and if I did wouldn't eat fish from the river.
