Welcome to StreamStats


StreamStats for Georgia can be used to estimate the magnitude of peak flows for Georgia under natural streamflow conditions at the 2-, 5-, 10-, 25-, 50-, 100-, 200-, and 500-year recurrence-intervals, which have the probability of exceedance in any single year of 50, 20, 10, 4, 2, 1, 0.5, and 0.2 percent, respectively. The report below presents the equations used to estimate the flow statistics, describes the errors associated with the estimates, and describes the methods used to develop the equations and to measure the basin characteristics used in the equations. Users should familiarize themselves with the report before using StreamStats to obtain estimates of streamflow statistics for ungaged sites.


Interactive Map


General information on the Interactive Map application, as well as specific sources and computation methods for basin characteristics are available here.


Information for streamgages that is provided in output from the Gaging Station Information tool has not yet been updated for Georgia. This information will be updated as soon as possible, and this notice will be removed at that time. Meanwhile, additional statistics can be found in the report above, as well as in the reports:

Streamflow estimates obtained for ungaged sites by use of the Estimate Flows Based on Similar Streamgaging Stations tool will be based on streamflow statistics from all three of the reports noted above.

StreamStats for Georgia was developed in cooperation with the Georgia Department of Transportation and the Georgia Environmental Protection Division.
