USGS StreamStats

<p><strong>Open the Data Resource:</strong> <a target='_blank' href='https://streamstats.usgs.gov/ss/' rel='nofollow ugc noopener noreferrer'>https://streamstats.usgs.gov/ss/</a></p><p>StreamStats is a Web application that provides access to an assortment of Geographic Information Systems (GIS) analytical tools that are useful for water-resources planning and management, and for engineering and design purposes. The map-based user interface can be used to delineate drainage areas for user-selected sites on streams, and then get basin characteristics and estimates of flow statistics for the selected sites anywhere this functionality is available. StreamStats users also can select the locations of U.S. Geological Survey data-collection stations, shown as triangles on the StreamStats map, and get flow statistics and other information for the stations. The types of flow statistics that are available vary from state to state. A variety of additional tools are available for discovering information about streams and the activities along them.</p><p>StreamStats works within Web browser software on personal computers and mobile devices, and is best viewed using the latest versions of Internet Explorer, Microsoft Edge, Chrome, or Firefox. The browser must allow HTML5 asynchronous script execution. The application is being continually improved and expanded. The News link in our left-hand menu will provide notices of any new enhancements.<br />The StreamStats home page provides links to a more detailed description of the program, a user's manual, descriptions of the outputs, definitions of basin characteristics and streamflow statistics, limitations for use of the application, and other information. The user's manual also can be accessed by clicking on the Help link on the user interface. Users should read the user's manual before attempting to use the application.</p>
