Water-level values for this site are now being published using the datum reference feet below land surface.
In order to convert the published values to a level in feet related to sea level, subtract the land surface values from the altitude of land surface, 18.10 (ft NGVD29).
The hydrograph below displays both feet below land surface and sea level scales on the dual Y-axes.
