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.
To
determine the impact of the drought on water resources and ecology of
southwestern Georgia and
adjacent parts of Florida and Alabama, almost two dozen researchers from three U.S.
Geological Survey (USGS) water science centers in Alabama,
Florida and Georgia will conduct field studies
in the Apalachicola-Chattahoochee-Flint and Aucilla-Suwannee-Ochlockonee river
basins over a 10-day period.
"This
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
Water Science
Center. "This effort
will help us see hydrologic and ecological conditions at their most stressed
condition."
USGS field
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.
Residents
interested in monitoring ground water levels across the country may visit GroundWater
Watch (http://groundwaterwatch.usgs.gov/),
a USGS Web site that displays maps, graphs and tables describing real-time,
recent and past ground water conditions for the United States, with real-time
data updated on an hourly basis, enabling viewers to compare historical ground
water levels.
