Station Notes
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/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 May 11, 2021, the gage height datum was converted to the
NAVD of 1988 datum. All reported gage heights and stage-discharge
ratings have been converted and are consistent with elevations
based on the NAVD88 datum. A conversion factor of +3.41 ft was used
to convert the old gage heights to the currently reported
instantaneous gage height and stage-discharge rating
points.
