How to read this gauge
The number is the stage in feet on this gauge's own scale, as the NWS publishes it. The NWS gives no datum for it, so it is not a depth and can't be compared with other gauges.
Readings the NWS marks out of service are left out, and so is any single reading more than 2 ft from the readings either side of it, which is a sensor error rather than water; a newest reading that far from the one before waits for the next to agree.
U.S. Army Corps of Engineers runs this gauge; the National Weather Service publishes its readings, which is where this site reads them.
