At this time one year ago, Lake Lanier was draining fast, full pool a long-ago memory. Conditions have reversed for the North Georgia reservoir as full pool adjusted Sunday for winter — dropping to 1,070 feet above sea level from 1,071 feet — and the area otherwise prepares for winter weather. The lake stood Sunday at 1,071.38 feet, increasing over the past week by nearly a foot, the result of rainy weather.
