Swimming and boating at Hartwell Lake near Anderson

Low water changes a lake fast for boaters. Some ramps get shorter or close, docks may be moved, and rocks and sandbars that are usually well under the surface come within reach of a prop.

If you swim, pick a spot with an easy way out, and remember that drop-offs move as the level changes.
