Torrens title system, Robert Torrens, a member of the colony's House of Assembly, proposed a new title system in 1858, and it was quickly adopted. The Torrens title system was based on a central registry of all the land in the jurisdiction of South Australia, embodied in the Real Property Act 1886 (SA). All transfers of land are recorded in the register. Most importantly, ownership of the land is established by virtue of the owner's name being recorded in the government's register. The Torrens title also records easements and the creation and discharge of mortgages. The historical origins of the Torrens title
River Torrens jammed, and in trying to free them the weir's designer John Langdon was crippled. The weir was rebuilt from 1928 to 1929 with its footbridge relocated and the centre section replaced. The gates can now be fully raised and the river allowed to flow unimpeded. The "Popeye" boats are privately owned recreational ferries that operate on the lake between Elder Park and the Adelaide Zoo. The first boat was launched on the Torrens Lake by Gordon Watts in 1935. It was a boat, built on the banks of the Torrens to hold up to 20 passengers and named "Popeye 1".
