Upper Floridan aquifer
South-central area
The water level in the Upper Floridan aquifer in south-central Georgia was monitored in three wells in 1999 and data from these wells are available as PDF files, accessible by clicking on the well number in the map below or from Table 3b. Water levels in wells tapping the aquifer in this area are affected by variations in precipitation, evapotranspiration, and to a lesser degree, pumping (Krause, 1979). In the Valdosta area (Lowndes County), water levels also are affected by streamflow (Krause, 1979). The water level is generally highest following the rainy seasons in winter and spring, and lowest in the fall. The Upper Floridan aquifer receives recharge from the Withlacoochee River north of Valdosta where water from the river flows directly into sinkholes and large solution openings in the aquifer. In this area, increased precipitation and streamflow in winter and early spring result in higher ground-water levels. During most years, decreased precipitation and increased evapotranspiration in the summer results in lower streamflow and correspondingly lower ground-water levels.
