Statement of significance:

Liverpool Weir demonstrates the history of the origins and development of an important urban utility in Liverpool. It is associated with prominent engineer Lennox and is a rare surviving example of his work, as built by Capt Christie in the mid 19th century. The Dam exhibits a level of technical achievement in its design and construction and is now a rare intact 19th century water supply structure. Extensive repairs were undertaken early in 2008 to arrest structural decline.

Description

Designer/Maker: David Lennox
Builder/Maker: Captain W H Christie
Construction years: 1836-
Physical description: Liverpool Dam is located directly east of Liverpool Railway Station, on the George's River. Access to the Dam is gained via the eastern bank of the watercourse. The access point is reached by heading east of Liverpool city centre on the Newbridge Road. On crossing the George's river a slip road (part of Heathcote Road) branches off immediately to the left (north) and leads directly to the riverbank.
The Dam is constructed of (probably) a clay base faced with large sandstone masonary blocks. The blocks are semi-circular on the downstream and on the upstream side a sloping surface crosses the river at an oblique angle.
The dam raises the water level in the river by c.2m and can provide an access across the Georges River.






The Dam is (probably) constructed with a clay base and faced with large sandstone blocks. Described in 1855 as raising level of water in the river by 2m. Repairs and additions made at various times, concrete road partly built across in 1973 but part of wall was washed away.
Physical condition and/or
Archaeological potential:
Both faces in good condition after reconstruction. A new surface has been laid across much of the weir.
Date condition updated:10 Jul 08
Modifications and dates: Extensive repairs in early 2008 undertaken by dnr following partial collapse late 2007
Former use: Dam/weir

History

Historical notes: The Liverpool Dam was constructed in 1836 to supply water to the town of Liverpool and served as a causeway across the George's River. It was designed by Australia's first major bridge builder/engineer the Superintendent of Bridges, David Lennox and constructed under the supervision of Capt. Christie of the 80th Regiment. Christie was then the assistant engineer and superintendent of Ironed Gangs in the Town of Liverpool. The Dam is one of few surviving works designed by David Lennox.
The weir remained the town's only crossing until the first bridge was built in 1894. A wharf and ship basin were constructed at the weir and boats upto 140 tons displacement carried timber and farm produce to Liverpool via Botany Bay.

The structure was originally a stone outer shell, covering a clay interior. Eventually the decades of floor-water caused considerable erosion and it has need repairing on several occasions with a major rebuilding in 1973.

The structure no longer serves its original purpose but by dividing the salt water from freshwater it maintains the ecology of the Upper Georges River.
