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 not reliable due to unsteady flow conditions during high flows. Under these conditions, a loop stage-discharge rating exists such that the true discharge is generally greater than indicated on a rising hydrograph and less than indicated on a falling hydrograph. Corrections are applied following a high-flow event but data remain provisional until approved. (Message posted February 20, 2015.)
