Welcome to the NWIS-Web for the Arizona Water
Science Center
The majority of USGS Gaging Stations are funded though a cooperative
program between the USGS other interested agencies.
Follow this link for information on the Cooperative Water Program with
the USGS.
Station operated in
cooperation with the Salt River Valley Water Users' Association
and the USGS.
The 15-minute precipitation data for this station
are temporary and will only be displayed for 120
days. Time series of 15-minute or cumulative daily values
will NOT be available for retrieval following the 120-day
display period. Although the instrumentation is calibrated at
least once per year, the temporary classification means that
documented routine inspections and other quality assurance
measures are not performed that would make the data
acceptable for archival, retrieval, or future use in general
scientific or interpretive studies.
This station managed by the Tempe Field Office; USGS AZ-WSC.
