This year, the U.S. Geological Survey recorded the lowest May streamflow in 115 years for the Oostanaula River at the Resaca gauge.

Rivers across the state are experiencing moderate to se-vere hydrologic drought. In addition to the Oostanaula re-cord, this was the lowest May streamflow recorded in 110 years for the Oconee River at the Milledgeville gauge, and 98 years for the Flint River at the Albany gauge. Streamflow was the lowest recorded for 50 years for any month for the Su-wannee River at Fargo.



The U.S. Geological Survey has been monitoring and re-cording stream flow for more than 100 years at many loca-tions throughout the state. The lowest May streamflow on record was recorded for 34 monitoring stations with at least 30 years of record in Georgia with many other rivers ap-proaching record lows.

"Little if any widespread, sustained relief from the drought is anticipated. The long-term outlook suggests the drought will continue to intensify," said Georgia State Clima-tologist David Stooksbury.

Normally the lowest streamflows of the year occur in late summer, when water use demands are highest, and fall, ac-cording to the USGS. If below average rainfall continues through the summer and fall, new record low flows are likely to occur in Georgia's rivers. With the conditions so dry this early in the year, it could create significant impacts to water supplies, ecological habitats and recreational uses. Already the agricultural industry has been heavily impacted by the drought.

"Extreme drought now covers most agricultural areas, de-laying peanut and cotton planting and raising concerns for the crops this year," said Brad Haire of University of Georgia.

"It is difficult to compare previous droughts with the ongo-ing drought while it is developing. During the previous cen-tury, hydrologic droughts have affected large portions of Georgia numerous times, with the most recent event from 1999-2002. Hydrologic droughts typically last for one or more years and may not have obvious beginning and ending times," explained Mark Landers, a USGS hydrologist.

Groundwater levels also are declining across Georgia, al-though the effects depend on the hydrogeology and pumping characteristics of specific aquifers. Many wells are approach-ing their average annual minimum water level, which nor-mally occurs in late summer or early fall.

The USGS and its federal, state and local cooperators maintain 233 streamgaging stations and 209 monitoring wells throughout Georgia.
