NOAA identifies station 8410140 as Eastport, Maine, at 44.90330° N and 66.98500° W.
NOAA’s published benchmark sheet places the tide station at the east end of the Municipal Pier in Eastport.
NOAA lists Eastport’s great diurnal range as 19.27 ft and its mean range of tide as 18.35 ft, both relative to the station’s MLLW datum.
The NOAA datum page lists MLLW as 0.00 ft for this station, so the numbers on this page use a local tidal reference rather than an elevation above land.
When you need an observed water level instead of a prediction, NOAA’s water-level station listing says its real-time water-level information updates every six minutes.
These values are predictions, not observations; wind, atmospheric pressure, storms, and runoff can make actual levels differ.
Eastport is a reference station, so no subordinate-station time or height offset has been applied.
NOAA’s prediction page says its raw prediction output is preliminary data for limited public use and should be used with appropriate caution.
