Editor's note: This story was originally published in December 2018. Mooresville resident Lauren Sullivan has a boat she takes out on Lake Norman from time to time. She and her husband will cruise across the water, sometimes towing a wakeboard from behind. Like most people, she knew the lake was man-made, and that got her wondering: what might have been swallowed up by all the water, and what happened to the people who once called the area home?
