USGS Diagram of How Streamgage Data is Transferred To The Internet.
Streamflow Data on the Internet All USGS stage and streamflow information is available in near real time through the National Water Information System Web Interface (NWISWeb) for Texas (fig. 5) at: http://waterdata.usgs.gov/tx/nwis/rt). In addition to real-time streamgage data, NWISWeb also provides access to daily discharges and annual maximum discharges for the period of record for all active and discontinued streamgages operated by the USGS. This information is used by the National Weather Service to forecast flooding and by emergency managers to make informed decisions to protect public safety in times of flooding.
