Water Use in Georgia, 2005
Total offstream water use from groundwater and surface-water sources was about 5,471 million gallons per day (Mgal/d) in 2005. Estimated groundwater withdrawals, which include water obtained from springs, were 1,180 Mgal/d in 2005, mostly for irrigation (41 percent) and industrial and mining uses (24 percent). Withdrawals for irrigation totaled 752 Mgal/d with 65 percent supplied by groundwater sources. In the southern Coastal Plain physiographic province of the State, many counties had more withdrawals from groundwater sources. In general, surface-water resources provide the largest percentage of water withdrawal for counties in the northern half of the State, whereas ground water provides the greatest percentage for counties in the southern half of the State. There are exceptions. For several northern Georgia counties, more than 50 percent of the total county withdrawal is obtained from groundwater, with groundwater withdrawals exceeding 60 percent in the relatively low water-usage counties of Catoosa, Madison, and Murray.
