Station Notes

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 height values.
