Summary Drought conditions have spread througout the entire ACF with drought in the central part of the basin categorized as extreme to exceptional Similarly, streamflows are below average streamflows throughout the entire basin, though inflows to West Point are normal because of releases from Lake Lanier Ground water levels in S Georgia remain at historic low levels Basin inflows are about 1600 cfsbelow outflows, so reservoir levels have continued to decline, with Lake Lanier approaching the threshold for conservation zone 4
Summary The 5-day outlook is for less than 1 inch of precipitation in the northern half of the basin and no rain in the southern half ENSO conditions remain neutral, so a total of 3 to 6 inches of rainfall are expected for the basin in each month of December and January Streamflow forecasts at 1 and 3 months all suggest that drought conditions will persist or worsen
