Facts About GeorgiaFacts About Georgia
◊ Northern quarter is southern highlands◊ Southern half is the coastal plain◊ Most of the population lives in the piedmont
◊ The fall line bisects the state (Montgomery, Columbus, Macon, Augusta, Columbia, Raleigh, Richmond and Georgetown)

Georgia Water Facts Georgia Water Facts
◊ North of the fall line - primarily surface water• Drainage basin for Lake Lanier 1040 sq. miles.
◊ South of the fall line - primarily ground water
◊ 1.5 million acres under irrigation, primarily in southwest Georgia

◊ Rule of Thumb: 50 inches of rain per year• More than 80 inches in the mountains• 45 inches interior southeast
◊ Rain is more or less evenly distributed over the year: March 5 inches and October 3.5 inches
◊ Evapotranspiration is extremely important in drought forecasting

Section 1) DROUGHT DECLARATION PROCESS
The following is the process for declaring drought conditions and responses:
1A): The State Climatologist’s office and EPD will routinely monitor and evaluate stream flows, lake levels, precipitation, groundwater levels, and other climatic indicators that are supplied by several cooperating entities …

Comments about DiscussionComments about Discussion◊ Drought impacts are cumulative - data may not
capture the essence of the drought
◊ Drought varies over time and space - part of the state may be in short-term drought while other parts are in long-term - the importance various indicators will vary from drought to drought and within a drought.
◊ Seasonal components are important as well antecedent conditions such as soil moisture, stream flows, reservoir levels
