Station Notes
Gage height datum conversion to
the NAVD88 datum for this streamgage was made effective as of
August 9, 2018. Instantaneous gage heights previous to that date
will remain as originally reported. However, mean gage heights
associated with all discharge measurements have been converted to
be consistent with elevations based on the NAVD88 datum. The
conversion factor used to adjust gage heights to NAVD88 from the
previously used arbitrary datum is 116.98 ft. For example,
prior to August 9, 2018 the gage height at a flow of 366 ft3/s had
a gage height of 3.51 feet. After August 9, 2018 and at the same
discharge, the gage height is 120.49 feet (3.51ft + 116.98 = 120.49
ft).
