235-484: Is exposed at low tide. Moorings and jetties are the responsibility of Transport for NSW , who are also responsible for the management of the Harbour and river seabed. Many bays contain swing moorings, mostly privately owned, but some associated with commercial marinas. Along the Parramatta River many hands have made lighter work, in the community-wide effort to make the entire river swimmable again by 2025 , starting with
282-690: Is fed by a number of small creeks and stormwater drains. The waters are controlled by a series of weirs : the weir at the edge of the hospital grounds, the Kiosk Weir in Parramatta Park, the Marsden Street Weir, and the Charles Street Weir at the ferry wharf. The weirs have been equipped with fish ladders . Kiosk Weir and Charles Street Weir also include footbridges enabling a crossing of the river. Historically,
329-620: Is merely "a surmise". Another possible explanation for the name is that it was derived from the Ironbark trees that used to grow there. The island in the middle of the bay is called Rodd Island , in honour of Brent Clements Rodd . Iron Cove is crossed by the Iron Cove Bridge , which was first opened in 1882 and links Rozelle and Balmain to Drummoyne. The original bridge was replaced in the 1950s. The Australian warships HMAS Ballarat and HMAS Goulburn were broken up for scrap in
376-412: Is noted as Iron-stone Cove. Iron Cove appears to be a shortening of this name that perhaps referred to the reddy coloured iron oxides in the stone, known as laterites . In his book on Sydney Harbour, P.R. Stephensen suggests that the name is derived from the iron shackles worn by convicts from Cockatoo Island who were forced to work in the area around the bay from 1839. However, he goes on to note that this

Additional land was carved from the Birchgrove House when it was sold to John Lowry Adams in 1878. A syndicate of businessmen purchased the remaining lots of the estate and commissioned architect Ferdinand Reuss to draw up a new plan for subdivision. This second subdivision
752-564: The University of Sydney 's School of Geosciences, this bay and its catchment area are the most heavily polluted in Sydney Harbour . In particular, very high levels of copper, zinc, and lead have been detected in the bay. Some of this pollution is contained in road dust, which is washed into the bay in stormwater. Iron Cove Creek (Dobroyd Canal) also suffers from organic and hydrocarbon pollutants. A proposal has been put forward for

Sale of the allotments fell well short of expectations with three lots remaining unsold by 1866. By December 1862, Joubert was forced to surrender his remaining interest to the Bank of New South Wales . From the 1860s, a number of waterfront businesses appeared in the area including coopers , boat builders and

There is a complete fishing ban in Homebush Bay because of the dioxin contamination. In 2006 the NSW Government imposed a complete commercial fishing ban throughout the rest of Sydney Harbour and its tributaries, including
1175-458: The bay in 1953. There are a number of smaller bays with Iron Cove, such as Sisters Bay and Half Moon Bay on the northern shores. The concrete channelised Iron Cove Creek runs into the western end of the bay, and Hawthorne Canal runs off the southern part of the bay. The land around the bay is mostly made up of publicly accessible foreshore or parkland. This forms a 7 kilometres (4.3 mi) jogging circuit known as The Bay Run . According to

Tram services branched off from the main line on Darling Street , Balmain, turning left into Rowntree Street, left into Cameron Street and right into Grove Street, before terminating at Wharf Road in Birchgrove. A Transit Systems bus service now follows the former tram route. Birchgrove was the southern portal of the first tunnel under Sydney Harbour. The tunnel
1269-603: The estate was purchased by merchant trader Roland Warpole Loane . By 1818, Loane had returned to land holdings in Tasmania and the estate was leased for many years. Loane unsuccessfully attempted to sub-divide the lot into four parcels in 1833. In 1838, the estate was purchased along with land in the Balmain estate by Captain John McLean. Financial difficulties forced McLean to mortgage the estate and additional land, but
1316-462: The first decade of the twenty first century, Birchgrove was a much smaller suburb bounded by Grove and Cove Streets. Birchgrove was named after Birchgrove House, built by Lieutenant John Birch, paymaster of the 73rd regiment, around 1812. He added 'grove' to his surname when naming the house because of the large number of orange trees growing on the original site. The house was constructed of stone believed to have been quarried on site. In March 1814,

The mangroves have actually colonised areas that were previously salt marsh. Research into historical drawings and writings indicates that
1551-466: The mangroves were far fewer at English colonisation. Council information panels in Glades Bay explain that the bay's now extensive mangrove stands would once have been open water, sandy beaches and outcrops of rock. Land clearing and development has allowed soil and various nutrients to be washed into the river. This has provided an ideal environment for mangroves to colonise. The excessive siltation of

1692-464: The river and the harbour have presented a formidable barrier between the early–European settled southern Farm Cove precinct, to development north of the waterway. Together, Parramatta River and Port Jackson literally cut Sydney in half along its north–south axis. As a result, the many crossings are extremely important to the life of the city. From west–to–east, the crossings of the Parramatta River are located at: With adjacent water pipe bridge on
1739-475: The river is an ongoing problem. Many areas of the river, particularly the swampy heads of bays, have been reclaimed , often being used as rubbish dumps before being converted into playing fields. Large sections of Meadowbank Park were created in this manner. Some industrial sites were also reclaimed heavily from the river, particularly in Homebush Bay. Most creeks leading into the bays have been channelised (lined with concrete walls and floor). While some areas of
