Georgia FloodWatchThis map, from USGS's WaterWatch Web site, shows the location of streamgages where the water level is currently at or above flood stage. The high-flow conditions are expressed as percentiles that compare the current (within the past several hours) instantaneous flow value to historical daily-mean flow values for all days of the year. Flood conditions may be more extensive than shown because the National Weather Service (NWS) has not identified a flood stage at all USGS streamgaging sites. The most complete depiction of streamgages at or above flood stage is on the NWS River Conditions Map. Flood Inundation MapsView flood-inundation maps for sites in Georgia.

Historic September 2009 floodingThe flooding around Atlanta in Sept. 2009 was one for the record books. Some rivers and streams had magnitudes so great that stages that high could be expected only once every 500 years.

Rainfall CalculatorAll the water in floods comes from the sky—but have you ever wondered just how many gallons of water falls on an area when it rains? You might be surprised at how much water comes down. Use our Water Science rainfall calculator to see how many gallons of water falls from the sky during a rainstorm. |
