Part of the "Tank Stream Sculpture" at Circular Quay in Sydney.

In 1788, when the First Fleet arrived in Australia, they found a stream of fresh water flowing into Port Jackson which influenced the choice of site for
the first Europrean settlement - Sydney. The Tank Stream originated from a swamp to the west of present day Hyde Park and emptied into the cove near
where Bridge and Pitt Streets intersect. As the settlement grew, the need for fresh water increased dramatically, placing great strain on the limited
water supply. During a drought in 1790, three holding tanks were dug along the watercourse. The stream soon became known as the Tank Stream.
Today, the Tank Steam still flows beneath the city as part of the stormwater system.

This fine work of art, commemorating the Tank Stream, was sculptured by Stephen Walker and presented to the city in 1981.
