Peak discharges on many streams in central and southwestern Georgia had recurrence intervals ranging from around 10 years to greater than 100 years. The most significant flooding in southwest Georgia occurred in the Flint River basin, with numerous streams having recurrence intervals ranging from around 25 years to greater than 100 years. New peaks of record were recorded at Spring Creek near Colquitt of 15.91 feet and at Spring Creek at Iron City of 24.65 feet. Peak-flow data have been collected at these gages for the past 17 and 56 years, respectively.
In central Georgia, the most significant flooding occurred in the Altamaha River basin. Several streams in the basin had recurrence intervals ranging from about 10 years to greater than 100 years. New peaks of record were recorded on 4 streams in the basin. These streamflow stations are fairly new, having only 6 to 15 years of peak-flow data available.
The table below contains the preliminary USGS peak-flow data collected for the period of March 8-15, along with recurrence intervals (as applicable) at selected active streamflow stations within the affected basins.
[sq mi, square miles; ft, feet above an arbitrary datum; cu ft/s, cubic feet per second; RI, Recurrence interval in years; --, not determined or not applicable; <, less than; >, greater than; *, New peak of record; ~, Approximate. Source: Recurrence intervals calculated from U.S. Geological Survey data. Other data from U.S. Geological Survey data bases]
