How to read this gauge
The number is the water surface elevation in feet on NAVD88, the current national vertical datum: a height above a fixed survey reference, not a depth. Readings on different datums can't be compared directly.
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.
U.S. Army Corps of Engineers runs this gauge; the National Weather Service publishes its readings and its flood stages, which is where this site reads them.
