Version 3 is still under construction but available for all states
StreamStats version 3 is now available for all states. StreamStats Version 2 was retired on July 14. The version 2 retirement was required because it was operated on computers that used an older operating system, which was considered a security risk for use on U.S. government servers.
Currently, users can get information for USGS data-collection stations throughout the U.S. Users also can get basin delineations, basin characteristics, and estimates of streamflow statistics from regression equations for user-selected ungaged sites in states that are implemented, as well as download shapefiles of the delineations that include whatever basin characteristics and streamflow statistics that have been calculated. All other functionality that was available in Version 2, including all tools that rely on stream-network navigation, will not be available until they can be redeveloped. It is planned to release the redeveloped tools as they become available, with a goal of having all functionality available by the end of 2015.
This notice will be revised as needed when changes are made to StreamStats. Please contact the StreamStats by email at GS-W StreamStats@usgs.gov if you have any questions.
StreamStats is a Web application that incorporates a Geographic Information System (GIS) to provide users with access to an assortment of analytical tools that are useful for a variety of water-resources planning and management purposes, and for engineering and design purposes. StreamStats users can select USGS data-collection station locations shown on a map and obtain previously published information for the stations. Users also can select any location along a stream and obtain the drainage-basin boundary, basin characteristics, and estimates of streamflow statistics for the location. The streamflow statistics that StreamStats can provide for data-collection stations and for user-selected ungaged sites vary among the states that are implemented in StreamStats and among data-collection stations within states. Estimates obtained for ungaged sites assume natural flow conditions at the site.
StreamStats also includes several tools that rely on searching along the stream network upstream or downstream from user-selected sites to identify stream reaches and water-related activities along the streams, such as dams and point discharges, and obtain information about those activities. In addition, users can obtain elevation profiles along stream channels and between points on the land surface.
Separate applications have been established for each state that has implemented StreamStats. The State Applications link at the left provides access to a web page that shows where StreamStats is available and where it is being implemented. Users can select an individual state application from the map or the pull-down list on the State Applications page to view an introductory page for the state, which contains a link to the StreamStats user interface. The introductory pages explain any unique functionality that is available for the state and provides citations to reports that document the methods implemented for the state.
Some StreamStats functionality has been made available as Web services, which allow other Web sites or desktop GIS applications to access this functionality. Currently, web services are available for drainage-area delineation, regression estimates for ungaged sites, streamgaging station information, and stream reach address determinations. The Available Web Services page describes these services in more detail.
StreamStats has been optimized for use with Microsoft Internet Explorer 10 or higher, or newer versions of Chrome and Firefox, with pop-up blocker disabled. The browser must allow HTML5 asynchronous script execution. The application is being continually improved and expanded. Please continue to return to this page to learn of any new enhancements. Contact us if you have any questions or difficulty in using StreamStats, or to obtain information about use of StreamStats Web services.
Users should familiarize themselves with StreamStats Description, Instructions, and Limitations (using the links on the left) before utilizing the application.
The StreamStats Web application provides access to automated procedures and very large, complex data sets. These data sets are known to contain occasional errors. Users are advised to carefully check all results for accuracy and to exercise their own professional judgment in evaluating the appropriateness of the results for their application. Basin delineations in particular frequently have been found to be erroneous. The Web site provides tools and base maps useful for verifying the accuracy of the basin delineations.
