The International Great Lakes Datum (IGLD) is the vertical height reference
datum used in the Great Lakes/St. Lawrence River System for engineering,
charting, channel dredging, navigation safety, power generation, and water
resource management. It is a coordinated datum between the United States and
Canada that ensures both countries are using the same reference for projects
in the Great Lakes basin. The datum origin, or zero, is defined as Mean Sea
Level at Pointe-au-Pere /Rimouski, Quebec, Canada at the mouth of the
St. Lawrence River. IGLD requires updating approximately every 25-30 years
to account for varying changes in the land surface elevations following the
retreat of the glaciers during the last ice age, referred to as Glacial
Isostatic Adjustment (GIA). The current IGLD 1985 was implemented in 1992.
IGLD 1985 uses dynamic heights as the vertical reference standard and lakes
station water level elevations are adjusted to provide a level geopotential
plane for lake level reference.
Dynamic height is the potential difference along the plumbline between the
vertical datum and a point of interest divided by a constant value of
gravity. In Canada and USA, the constant value of gravity is the
"normal gravity" on the ellipsoid at latitude 45° (9.806199 ms-2). Dynamic
heights have no geometric meaning. They are mainly used for the management
of water in large lakes, rivers and channels. The surface of a lake has a
constant dynamic height if undisturbed by currents, winds, atmospheric
pressure, etc.
The Hydraulic Corrector (HC) is the difference in the long term water level
mean between Subordinate and Master station. The difference (HC) is
subtracted algebraically at the subordinate gauge referencing the same
elevation as the master station. Thus all water levels on a given lake can
be referenced to the same lakes LWD/Chart Datum reference elevation.

A Master Stations is the control point for determining water level
elevations on a particular lake of the Great Lakes. Since water surfaces
of the Great Lakes are considered to be at geopotential equal, all Mean
Water Level (MWL) values for stations on a particular lake should have the
same dynamic height. Therefore, all subordinate water level station MWL
values are adjusted to match the dynamic water level elevation of the Master
Station through the use of a hydraulic corrector. In the establishment of
International Great Lakes Datum (1985) the connecting waterways station
dynamic elevations were calculated through the use of a linear regression
while constraining the end points of the regression with the dynamic
elevations of the corresponding master station above and below the
connecting channel.
NAVD88 is a fixed datum derived from a simultaneous, least squares, minimum
constraint adjustment of Canadian/Mexican/United States leveling
observations. Local mean sea level observed at Father Point/Rimouski,
Canada was held fixed as the single initial constraint. NAVD88 replaces
NGVD29 as the national standard geodetic reference for heights. Bench mark
elevations relative toNAVD88 are available from NGS through the World Wide
Web at National Geodetic Survey.
The Vertical Mark Number (VM#) and PID# shown on the bench mark sheet are unique
identifiers for bench marks in the tidal and geodetic databases, respectively.
Each bench mark in either database has a single, unique VM# and/or PID# assigned.
Where both VM# and PID# are indicated, both tidal and geodetic elevations are
available for the bench mark listed. The NGS's Integrated Data Base (IDB PID)
provides geodetic datum based on traditionally leveled and bluebooked ties to
the National Spatial Reference System(NSRS) https://www.ngs.noaa.gov/datasheets/.
The NGS Online Positioning User Service (OPUS PID) provides geodetic datum based
on GPS position & tie it to the NSRS https://www.ngs.noaa.gov/OPUS/.
