How to read this gauge

The number is the observed water level relative to mean higher high water (MHHW), the average height of the higher of each day's two high tides at this station. 0 ft is an ordinary high tide; +1 ft is a foot higher than that. It is the water surface, not a depth, and it includes the tide and anything on top of it: storm surge, wind pushing water in or out, river flow.
