Streamflow and ground water conditions in southwestern Georgia and adjacent parts of Florida and Alabama continued to worsen during July. Waterways in many of the regions rivers are setting new record lows with gauges on the Flint, Suwannee, Ochlocknee, Alapaha and Apalachicola rivers recording the lowest water levels in their history due to lower than normal rainfall. Ground water levels were below normal and set new records in much of the southern Georgia, with some wells going dry.

is the first effort of its kind ever completed during the peak of the summer
irrigation season," says Brian McCallum, assistant director of the USGS Georgia
Center. "This effort

crews will visit more than 200 stream sites and 400 private and public supply
wells to assess streamflow decline and drops in ground water levels.
Additionally, field crews will collect water-quality information that will help
in the determination of the drought's impact on ecological conditions in the
region. Later in the summer, they will visit the same stream sites to assess
populations of fish and mussels affected by drought conditions. The work is
being completed as part of the USGS WaterSmart initiative, a program to assess
sustainability of water supplies in the ACF basin.
