Tank Stream, a fresh water tributary of Sydney Cove, located in New South Wales, Australia, was the fresh water supply for the fledgling colony of New South Wales in the late 18th century. Today it is little more than a storm water drain. It originated from a swamp to the west of present-day Hyde Park and at high tide entered Sydney Cove at what is now the intersection of Bridge and Pitt Streets in the Sydney central business district. The catchment was 65 hectares (161 acres), corresponding roughly the size of the Sydney central business district.
Excavations around Tank Stream have uncovered aboriginal flake stone artifacts made from water-worn pebbles. The stream is thought to have given the Aboriginal people fresh water, fish and other resources. The area was chosen by the commander of the First Fleet, Captain Arthur Phillip, R.N., in 1788 as the location for the New South Wales colony for similar reasons.
The colony had originally been planned for Botany Bay, on the recommendation of Sir Joseph Banks who had visited the area with Captain James Cook 17 years earlier, but when no fresh water was found there, Phillip sought a better site, and found it in the previously unvisited Port Jackson. Sydney Cove was chosen for settlement as it "was at the head of the cove, near the run of fresh water which stole silently along through a very thick wood". On 26 January 1788 the new colony was inaugurated.
The Tank Stream rose in marshy ground roughly bounded by what is now Elizabeth, Market, Pitt and Park Streets. It filtered through the soil between Pitt and George Streets before forming a definite channel near King Street and flowing to Sydney Cove.
