   5 days ago · All lake level values are shown in feet above sea level per NGVD29 datum. The US Army Corps of Engineers (USACOE), and NYSDEC typically currently use NGVD 29 datum. However, it is probably only a matter of time before the government agencies convert to using NAVD 88 datum, which for our area is about 0.51 ft. higher.

   5 days ago · To facilitate a smooth transition, benchmarks of the vertical control network are currently assigned mean sea-level elevations in both CGVD28 and CGVD2013. CGVD28 elevations result from an adjustment of all vertical levelling lines observed in Canada over a period of almost a century.

   Is the 'above mean sea level' based on NAVD 88?

   • Another surveyor was asked to use the term "Above Mean Sea Level" for a '1A' letter on an existing cellular tower. His measured elevations are based on NAVD 88 and from what I have read, MSL is irrelevant to NAVD 88. I told him I wouldn't use the "Above Mean Sea Level", only the datum. Am I wrong ?

   Is NAVD considered a sea level datum?

   • But yes, the OP is correct, NAVD is not considered a "sea level" datum. Newtonsapple is absolutely correct. NAVD 88 and even NGVD 29 are not the same as Mean Sea Level. MSL, which should actually be referenced as Local Mean Sea Level (LMSL) can only be defined in the very local vicinity of the shore line.
