The Parramatta River is the main tributary of Sydney Harbour, along with the smaller Lane Cove and Duck Rivers.
Until 1970 the river was an open drain for Sydney's industry and consequently the southern central embayments are contaminated with a range of heavy metals and chemicals. The Northern Bays are less affected as the Sydney harbour Bridge was not completed until 1932 and so industrial development was already well established on the southern side of the Harbour.
Dr Gavin Birch of Sydney University has published a number of papers which show that Sydney Harbour is as contaminated as most other harbours in industrialised cities, that the main sediment contamination is in the southern central embayments (Blackwattle to Homebush Bays), that there are 5 particularly contaminated areas of Sydney Harbour, and that 4 of them are in the Parramatta river system.

Some of the school rowing sheds are:
Most rowing training is done in the middle to upper reaches of the river between Abbotsford and Homebush Bay because there is less water traffic and therefore less waves and more protection from wind. Rowing also takes place in the Lane Cove River and Iron Cove which also have less traffic.
The mangroves have actually colonised areas that were previously salt marsh. Research into historical drawings and writings indicates that the mangroves were far fewer at English colonisation.

Contamination
Water Quality
Water quality is monitored by the NSW EPA for faecal coliforms and e. coli and but only as far west as Cabarita. In spite of the large scale high density development taking place further west on the River, and the use of the river further west for sailing, Sea scouts and rowing the EPA refuses to monitor water quality in those areas. in the areas monitored the water quality is generally acceptable except after heavy rains.Fishing
The Parramatta river is subject to a number of fishing bans because of its contaminated sediments. There is a complete fishing ban in Homebush Bay because of the dioxin contamination. There is a ban on commercial fin fishing west of the Gladesville Bridge. Perhaps because of these bans there is a reasonable variety of fish in the lower reaches of the river, although it would not be advisable to eat fish caught west of the Gladesville Bridge on a regular basis.Healthy Rivers Commission Needed
The Parramatta river is one of the only significant coastal rivers in NSW which has not been the subject of a Healthy Rivers Commission Investigation. Even the Cooks River and Botany Bay have been subject to such an investigation. A Healthy Rivers Commission inquiry would bring together all the information on the state of the river and its sediments and fish and assist in Catchment Management.
Sydney Harbour Catchment Management Blueprint
The whole of sydney Harbour including its tributary rivers is now subject to a long range Catchment Management Plan. While it is largely in the information gathering and policy development stage, it is now a formal NSW Government policy. Unfortunately the Government has almost eliminated local representation by disbanding the former local catchmnent management boards.Sharing the Foreshore
The NSW Government has a documented policy in relation to access to the harbour and river foreshores, including public access to intertidal lands where landowners have absolute waterfronts, but where the waterfront is exposed at low tide.Moorings and Jetties
Moorings and Jetties are the responsibiliety of Waterways, who are also responsible for the mananagement of the Harbour and river seabed. Many bays are choked with swing moorings, mostly privately owned, but some associated with Marinas.Marinas and Boatsheds
Ferry services and wharves
There are River Cat services along the Parramatta River to Circular Quay. The main wharves are
(to be completed)SREP 22
SREP 22 is a planning instrument governing development along the foreshore. It is effectively ignored by the State Government on major developments along the foreshore, even on State Government owned sites such as the Balmain power Station site and Waterways former Union Carbide site. See also the development at Birkenhead Point from the water near Iron Cove Bridge.Sailing
There are a number of sailing and yachting clubs on the River:
Sailing and rowing take place under an aquatic licence granted annually by Waterways.Sea Scouts
There are Sea Scouts at:
Rowing
The river has a long historical association with river. Therre is a monument in honour of Henry Searle, a champion sculler of his day, in the river at Henley.
There are also a number of rowing clubs:
While a number of regattas are still ehld on the river each year, mainly in Iron Cove, many fo the major regattas are now ehld at the Penrith International Regatta Centre where rowing was held for the 2000 Summer Olympics.Foreshore Walks and Cycleways
Much of the foreshore is still in the hands of industry and private individuals as residences, however there is an increasing amount of waterfront land available as foreshore reserve with walkways and cycleways. As former industrial sites undergo remediation and redevelopment the foreshores are opened up for public access. Where there is no foreshore access cycleways are routed through quiet residential streets with clearly marked sections of the road reserved for cyclists.Major Foreshore Parks
Major foreshore parks include:
Heritage items on or near the Foreshore
Major heritage buildins on or near the foreshsore include:
Major Wetlands and Environmentally sensitive areas
Major wetlands include:
There are significant stands of mangroves along the river west of Ryde (on the North shore) and Mortlake (on the southern shore) and in the Lane Cove river.Reclamation
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 also reclaimed heavily from the river, particulalry in Homebush Bay. Most creeks leading into the bays have been channelised (lined with concrete walls and floor).Remediation
While some areas of the river with heavily contaminated sediments have not been remediated, thee is significant remediation of sediments about to start in Homebush Bay. These include the dioxin contaminated sediments near the former Union Carbide plant and the lead contaminated sediments near the former Berger Paints plant. Unfortunately the EPA has allowed the sediments to get out of synch with the land based sites on which the polluters operated. The former AGL site has been analysed, a remediation plan developed and approved, remediation completed and construction commenced on medium to high density residential development, but the sediments, which independent research shows to be contaminated with pollutants from the AGL operations, have not yet had the investigation stage finalised (as of 2000). Other areas have had sediments covered with concrete to prevent the fish eating the benthos. the argument that the contamination is best left alone should be critically examined with a degree of scepticism because it ignores that the benthos are eating the contaminants and then passing the contamination up the food chain. the polluters face costs of tens of millions of dollars and so their protestations should be very critically examined.
