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.

The flood stages are the National Weather Service's references for this location, on the same scale as the reading. They describe the gauge, not any particular street or property.

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.

The NWS does not name the agency that runs this gauge; the National Weather Service publishes its readings and its flood stages, which is where this site reads them.
