Cretaceous Aquifer

Water levels in 10 wells in the Cretaceous aquifer system were used to define groundwater conditions throughout central and southwestern Georgia. In this area, water in the Cretaceous aquifer system mostly is confined but can be unconfined in stream valleys. Hydrographs for selected wells (below) illustrate monthly mean water levels for the period of record. The hydrographs show periodic upward or downward trends that largely reflect changes in pumping.

Well Locations with Ten Year Trend Icons

up arrow icon down arrow icon    Arrow icons represent upward or downward water level trend. Calculations based on last 10 years of data.
dot icon    Dot icon represents trend slope less than 0.01 ft/yr. or less than 100 data points from the last 10yrs. of data.
