Blue Lake by David Sornig is part history, part biography and part personal reflection on a much overlooked part of Melbourne's landscape. Situated to the west of the city lies a tract of land, Dudley Flats, that was once a lagoon but embodies the social, industrial and cultural changes to Melbourne over time. It was a marshland, waste dump, shanty town and shipping centre but is still often overlooked by Melbournites.
