Streamflow Statistics Definitions
The StatLabel, as shown in the first column of the table below is given as the statistic name in the StreamStats output for ungaged sites. The actual names of the statistics are given in the Statistic Name column, and their definitions are given in the Definition column. Each statistic in the table below has an associated standard error of estimate that will be provided in the StreamStats output, if it is available. Streamflow statistics are determined for data-collection stations from a limited sample of data; therefore, the statistics are not known with exact precision. The standard error of estimate, in percent, is an indication of the accuracy of the statistic. The actual values of the streamflow statistics will be within the given standard errors of estimate approximately two-thirds of the time.
