The USGS has been collecting some data – well actually, tons of data from the recent record event taken place in Georgia. From the USGS, The flooding around Atlanta this week is one for the record books. According to the U.S. Geological Survey (USGS), the rivers and streams had magnitudes so great that the odds of it happening were less than 0.2 percent in any given year. In other words, there was less than a 1 in 500 chance that parts of Cobb and Douglas counties were going to be hit with such an event. More information on USGS flood-related activities is available at the USGS Surface Water Information Web site.See below for some impressive before/after photos from the USGS!
