The Wentworth Creek Dam was constructed in 1892-1893.
Its purpose was to create a water reservoir for the City of Sydney to service approximately 2,400 residents.
The Dam was constructed of large hand-cut stone blocks with mortar joints.
It held back the waters of Wentworth Creek (now named Reservoir Brook), and was sized to retain approximately 6 million imperial gallons (27 million litres) of water.

A 10" diameter cast iron transmission main was laid following the creek valley floor, carrying the water from the new reservoir to the City of Sydney, and a network of distribution and service lines were installed by Fall 1883 when the system went into full operation.

By 1901 a booming steel industry and an increase in population placed a large demand on the Sydney water supply and subsequently the Wentworth Dam supply was inadequate to meet the demands of the city.
In 1902 a secondary dam was constructed upstream on Sullivan's Brook.
This new dam had a capacity of 200 million imperial gallons (910 million litres) of water and draws from a watershed of approximately 1,800 acres (730 ha).
This dam is located across the 125 Highway from the Cape Breton Regional Hospital.

As the new dam had an overflow elevation 30 metres (100 feet) higher than Wentworth Dam, the Wentworth Dam supply could not be integrated into the new water supply and therefore large diameter water transmission piping was installed and connected into existing piping downstream from Wentworth Dam.
This new water transmission piping continued along Reservoir Brook entering the Sydney water distribution system at Cromarty Street.
