How to read this gauge
The number is the water surface elevation in feet on NGVD29, an older national vertical datum (NGVD29 and NAVD88 heights differ by an amount that varies from place to place): 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.
