Station Notes
gage
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.)
