Abstract
The Georgia Water-Use Program, a joint project
between the U.S. Geological Survey (USGS), and the Georgia
Department of Natural Resources, Environmental Protection
Division, Georgia Geologic Survey, has collected, compiled,
and disseminated data about the principal water users in
Georgia since 1978. Water-use data from various Federal,
State and local agencies are compiled annually and placed in a
centralized data base known as the Georgia Water-Use Data
System (GWUDS). GWUDS contains water-use information
about public-supply, industrial, commercial, thermoelectric,
and hydroelectric uses from 1980-95. The USGS also
estimates water withdrawals for irrigation, domestic, and
livestock uses.
The water-use estimates for every fifth year are compiled
and published as part of the National Water-Use Information
Program. The Georgia Water-Use Program prepared
water-use estimates for 1995 for 13 categories of water users
by county and hydrologic unit for both surface- and
ground-water sources; water use by aquifer was estimated for
ground-water sources. During 1995, total off-stream
withdrawals were estimated to be 5,820 million gallons per
day (Mgal/d) in Georgia. (Category estimates do not toal
because of independent rounding.) Of this total, about 80
percent was from surface-water sources and 20 percent was
from ground-water sources.
Withdrawals for 17 thermoelectric power-generation
plants totaled 3,070 Mgal/d. These plants generated an
estimated 92,700 gigawatt hours of electricity. Thermoelectric
power-generation plants are the largest off-stream water users
and the withdrawals mostly were from surface-water sources.
Public suppliers withdrew 1,150 Mgal/d in 1995; industrial
and commercial users withdrew 680 Mgal/d and about 50
Mgal/d, respectively. About 720 Mgal/d were used to irrigate
an estimated 1.2 million acres Statewide. Domestic
withdrawals, which are assumed to be solely from
ground-water sources in Georgia, was estimated at about 100
Mgal/d. Withdrawals for livestock totaled about 30 Mgal/d.
Hydroelectric power generation, the only instream use
compiled by the Georgia Water-Use Program, totaled about
50,900 Mgal/d in 1995 for 38 hydroelectric plants in Georgia.
