History of the site

Shortly after 1808, William Lawson was appointed aide-de-camp to George Johnston and was granted convert|500|acre|km2 at Prospect, which he named Vereran Hall. He built a 40-room mansion there. He died on the property on 16 June 1850 and the property was eventually acquired by the Metropolitan Water Board. The house was demolished in 1926 and most of the property is submerged. [cite web

Construction

The dam itself was the first earthfill embankment dam in Australia, being completed in 1888. At the time it was intended to deliver water to the reservoir from the Nepean River.

In May 1940 the reservoir became a part of the Warragamba Emergency Scheme. Pipes were constructed to deliver water 26 kilometres from Warragamba. [cite web

Continuing use

Since the Prospect Water Filtration Plant was completed in 1996, untreated water is generally not drawn from Prospect reservoir any more. Instead, the water is piped to the filtration plant directly from Warragamba Dam. The reservoir remains a part of Sydney Water's storage network, however it is anticipated that it will only be utilised for water supply purposes on average of five days in any five year period [ cite web
