In Georgia, total offstream water use from ground- and surface-water sources was estimated to be 6,490 million gallons per day (Mgal/d) in 2000. Thermoelectric power was the largest category of offstream water use in 2000, estimated to be 3,310 Mgal/d from surface water. Instream water use for hydroelectric power plants in the State of Georgia was estimated to be 31,900 Mgal/d. Withdrawals for irrigation mostly were from ground-water sources, and withdrawals for public supply mostly were from surface-water sources. Offstream water use for 2000 was about 21 percent larger than in 1950. Statewide, from 1950–2000, water-use trends show the relation between water withdrawals and changes in population and climate. During that 50-year period, the largest category of water withdrawals has been thermoelectric power. Public supply has increased steadily since 1950 along with the State’s population.
