Summary of Hydrologic Conditions in Georgia 2002

During January 2002, all of the index stations showed significant decreases in monthly mean streamflow from the previous month. Most of the State received near normal rainfall for the month, which helped to sustain monthly streamflow across most of the State. In January, monthly streamflow in the northern part of the State increased from the previous monthly flows (about 15-60 percent of normal), and ranged from about 35-75 percent of normal. Monthly streamflow in central Georgia showed slight increases from the previous monthly flows (about 25-30 percent of normal), and ranged from about 25-50 percent of normal. Monthly streamflow in the southern part of the State remained about the same as the previous monthly flows (about 2-50 percent of normal), and ranged from about 2-45 percent of normal.

For the month of January, 4 of the 15-index streamflow stations recorded a new monthly minimum flow:

During February 2002, all of the index stations showed significant decreases in monthly mean streamflow from the previous month. Most of the State received below normal rainfall for the month, which caused an overall decrease in monthly streamflow across most of the State.

During May 2002, most of the index stations showed a decrease in monthly mean streamflow from the previous month. Rainfall amounts across the State varied widely, with some areas of the State receiving near normal rainfall for the month, and other areas receiving little or no rainfall. This highly variable rainfall amounts, caused an overall decrease in monthly streamflow across most of the State. In May, monthly streamflow in the northern part of the State increased from the previous monthly flows (about 40-65 percent of normal), and ranged from about 50-65 percent of normal.

During November 2002, all of the index stations showed significant increases in monthly mean streamflow from the previous month. Rainfall amounts across the State varied widely, with some areas of the State receiving near or above normal rainfall for the month. These variable rainfall amounts were enough to cause an overall increase in monthly streamflow across the State. In November, monthly streamflow in the northern part of the State increased from the previous monthly flows (about 70-170 percent of normal), and ranged from about 130-150 percent of normal. Monthly streamflow in central Georgia showed increases from the previous monthly flows (about 70-120 percent of normal), and ranged from about 90-150 percent of normal. Monthly streamflow in the southern part of the State also increased from the previous monthly flows (about 25-200 percent of normal), and ranged from about 130->200 percent of normal.

For the month of November, none of the 15-index streamflow stations recorded new minimum monthly flows or minimum daily flow of record.

During December 2002, monthly mean streamflow for all of the index stations remained about the same as the previous month. Rainfall amounts across the State varied widely, with some areas of the State receiving near or above normal rainfall for the month. This variable but consistent rainfall amounts were enough to maintain or cause an overall increase in monthly streamflow across the State. In December, monthly streamflow in the northern part of the State increased somewhat from the previous monthly flows (about 130-150 percent of normal), and ranged from about 120-170 percent of normal. Monthly streamflow in central Georgia showed no significant increases from the previous monthly flows (about 90-150 percent of normal), and ranged from about 75-170 percent of normal. Monthly streamflow in the southern part of the State also showed no significant increases from the previous monthly flows (about 130-200 percent of normal), and ranged from about 80-170 percent of normal.

For the month of December, none of the 15-index streamflow stations recorded new minimum monthly flows or minimum daily flow of record. < /p>
