Station Notes
The
15-minute precipitation and air temperature 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/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.
On Feb. 1, 2021, the National
Weather Service updated the minor flood flow level to 4,000
cfs. (Message posted Feb. 3, 2021)
