An area known as the “Styrofoam graveyard” in a Lake Lanier cove off Clarks Bridge Road is about to get cleaned up. Several groups, including Keep Hall Beautiful, Gainesville-Hall ’96 and Lake Lanier Association, are set to remove tons of Styrofoam debris next week from the area, which is near the Lake Lanier Olympic Park. And they’ve got the lingering drought to thank for that — at least partially.
