Now that Lake Lanier is hovering around full pool, Hall County is moving forward on a major culvert repair project in West Hall. Officials have said they needed the lake to drop to at least 1,071 feet above sea level before they can proceed on the work on Big Creek at McEver Road, near Buford city limits and Lake Lanier. The lake now is in its designated period of winter full pool, or 1,070 feet.
