[Talk-ca] Missing harbours and marshes - L Ontario

[Bob Dustan]

I just noticed that several small bodies of water along the north shore
of Lake Ontario have disappeared (partially or completely).  Some
harbours affected are Oshawa, Bowmanville, Newcastle, Port Hope, and
Cobourg.  Some marshes (e.g. Westside Marsh near Bowmanville) are gone. 
Some creek/river sections near the shore are gone as well.

Can someone clarify what is happening with this?

Regards,
Bob
