| United States Geological Survey (USGS) Streamflow
Network - The USGS (part of the US Department of the Interior) operates this
network of 7237 streamflow gages (162 in Arizona) at locations throughout the US.
The network provides hourly or more frequent observations of stage (water level) from
which discharge (flow) is comuputed using a stage-discharge rating relation. The
rating is defined by occasional direct current-meter measurements of discharge. All
data are available through the USGS and the district offices in each state. Many of
these gages provide realtime data
relayed via the GOES satellite data collection system. The realtime data are
provisional data that have not been reviewed or edited. These realtime data
may be subject to significant change and are not citeable until reviewed and approved
by the USGS. Realtime data may be changed after review because the stage-discharge
relationship may have been affected by: 1) backwater from ice or debris; 2) algal and
aquatic growth in the stream; 3) sediment movement; and 4) malfunction of recording
equipment. Each station record is considered provisional until the data are
published. The data are usually published with 6 months of the end of the water year
(1 October to 30 September). Data users are cautioned to consider carefully the
provisional nature of the information before using it. For further information on the
USGS stremflow network visit the USGS Water Resources of the United States page at:
