Georgia StreamStats

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

New equations were added to StreamStats on June 15, 2017 for estimating the annual minimum 1- and 7-day average streamflow with the 10-year recurrence interval (referred to as 1Q10 and 7Q10), monthly 7Q10, and mean annual flow for northern Georgia (Gotvald, 2017). StreamStats also can be used to estimate the magnitude of peak flows throughout Georgia under natural streamflow and urbanized 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 reports below present the equations used to estimate the flow statistics, describe the errors associated with the estimates, and describe the methods used to develop the equations and to measure the basin characteristics used in the equations. Users should familiarize themselves with the reports before using StreamStats to obtain estimates of streamflow statistics for ungaged sites.
