Blackwattle Bay is in the Inner West suburb of Pyrmont, about 2 kilometres west of the Sydney central business district. The history of the Bay was a swamp. Reclamation of the swamp began in 1876, when seawalls were built and the swamp filled in by silt deposits from harbour dredges. The creek was eventually channelled underground, and the swamp later filled in to make Wentworth Park. Far view of the photo is the Wenworth Park covering the Blackwattle Bay.
