HOW ARE DATA STORED AND MADE AVAILABLE TO THE PUBLIC?

Before 1995, near realtime discharge data were stored in USGS databases and provided to major users via modem (telephone line) communications with USGS computers. Although data are still stored and available in USGS databases, advances in technology have made streamflow information more accessible to the general public.

In 1995, the USGS began to provide realtime discharge data to governmental agencies and the general public through the World Wide Web (WWW). By 1996, hourly streamflow data were available for more than 2,600 sites. In addition to stream discharge data, hydrographs (graphs representing change in stage or discharge over a period of time) are also available for many stream-gaging stations.

Since its inception, the USGS has prepared annual reports listing all daily streamflow values at each gage. These reports are prepared for each state and are available in many libraries or can be purchased from the U.S. Government Printing Office.
