How to read this gauge
The number is the observed water level relative to NAVD88. This station publishes no tidal datum, so it can't be stated against an ordinary high tide. It is the water surface, not a depth.
The NWS coastal flood thresholds are the National Weather Service's references for this station: water at or above the minor level is where flooding of low-lying areas begins. They describe the station, not any particular street or property. This site shows readings only, never tide predictions.
