Welcome to StreamStats

(New Update 07/01/2015)
Transition to Version 3 -- Pardon our Dust!

StreamStats Version 2 will be shut down beginning on July 14, 2015. The servers on which version 2 is operated use the Microsoft Windows Server 2003 operating system. This operating system is no longer supported by Microsoft, and it is now considered a security risk for use on U.S. government servers. Consequently, Version 2 will be shut on July 14.

StreamStats Version 3 functionality is still in development. 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, but it may take several months before all version 2 functionality is restored.

This notice will be revised as needed when changes are made to StreamStats. Please contact the StreamStats by email at GS-W 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 version xx and above, and Google Chrome version xx and above. Other internet browsers are not supported. 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.
