| Central and Arctic Region's
Permanent Gauging Network
The Tides,
Currents and Water Levels Unit operates a permanent
network of tide and water level gauging stations. There
are thirty-three stations on the Great Lakes and
connecting rivers and one additional tidal station on
Hudson Bay at Churchill, Manitoba. The gauging network
was established to provide the data required by CHS for
hydrographic surveys, the production of nautical charts
and publications and the safety of navigation.
This
network of gauging stations are equipped with SUTRON
8210™ Data Loggers which record water level heights
at 3 minute intervals using a Float - Counterweight
driven encoder. These data are transmitted via telephone
on a daily basis to a central collection station at our
Burlington, Ontario office.
