Flood gauge
Measured water, not the tide
This column is a different instrument. A flood gauge reports the water level that is there now and the stages where flooding starts. The orange square on the map is that gauge. It is often not on top of the tide station.
No coastal flood gauge is published within 15 miles of this station.
