Stage vs. flow — how to read a river gauge
Discharge (flow, in cubic feet per second) is comparable between gauges and is usually the better number for judging whether a river is up or down. Gage height is the water surface in feet above each gauge's own local datum, so it is local: the same 4 ft describes different rivers at two different gauges, and it is not the depth of the water. A gauge that reports nothing is shown as not reported — never as zero.
