TABULAR DATA:
How do Water Planning Regions of Georgia compare in their anticipated water use?
Projected withdrawals from groundwater (GW) and surface water (SW) are shown for key years from 2011 to 2050 for each county of the region. Since it is not possible to anticipate whether a given year will have rainfall patterns of wet, dry, or normal years, withdrawal amounts are shown for each.
(Values are annualized pumping rate (MGD) for all major and specialty agricultural commodities.)
