The StreamStats Program


Beta Version 3 is now available for Washington

A beta version of StreamStats version 3 is now available for Washington. Links to both the version 2 and the beta version 3 applications are provided below. Currently, beta version 3 can only delineate drainage basins, compute basin characteristics, and estimate streamflow statistics using regression equations for user-selected sites; however, it provides several new options for quickly locating (zooming into) sites of interest, as well as access to new regression equations for estimating streamflow statistics at user-selected sites, as noted below . Beta version 3 also can provide reports of information for USGS data-collection stations. The version 2 application should be used for all other functionality until version 3 can be made fully functional. Links to user instructions for both applications are provided to the left of this page. Although the results provided by the beta version 3 application for Washington have been fully quality assured, users may experience some user interface performance issues while version 3 development proceeds.

Two reports document the regression equations available in StreamStats for Washington, the errors associated with the estimates, and the methods used to develop the equations and to measure the basin characteristics used in the equations. Users should familiarize themselves with these reports before using StreamStats to obtain estimates of streamflow statistics for ungaged sites.
