Notice:
Period of record water-level data 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 data values from the altitude of land surface at this location, 129.40 (ft NGVD29).
The hydrograph below displays both feet below land surface and sea level scales on the dual Y-axes.
This station managed by the MD-DE-DC Water Science Center Baltimore office.
