How Will the IGLD (2020) Update Impact You?

We cherish our nation’s water resources for the vital role they play in our lives and livelihoods. At CO-OPS we understand that an update to the International Great Lakes Datum may mean something different for you than it does for others in your community.

The following regional operations and services will be impacted:

  • Water level regulation and forecasting
  • Economic viability and safety of commercial and recreational navigation, including charts, ports, harbors, and dredging in navigation channels;
  • Coastal zone management and planning, including flood erosion predictions and response, coastal structure design, construction and maintenance.
  • Coastal habitat restoration under the Great Lakes Restoration Initiative.
