At this site, near-real-time
provisional discharges greater than 9,000 ft3/s (gage heights
greater than about 50 ft) are less reliable due to unsteady flow
conditions during high flows. Corrections are being applied in
real-time to account for the looped stage-discharge rating effects,
but some loss in accuracy can be expected. (Message posted
August 18, 2017.)
The datum of the gage has been
determined to be 2.12 ft above NAVD 1988. To obtain stream
water-surface elevation values in NAVD 1988, add 2.12 to gage
