The Lane Cove River, a northern tributary of the Parramatta River, is a youthful tide-dominated, drowned valley estuary[1] west of Sydney Harbour, located in Sydney, New South Wales, Australia. The picturesque river is a tributary of the Parramatta River, winding through a peaceful bushland valley. It joins Parramatta River at Greenwich and Woolwich, where together they form an arm of Sydney Harbour.

Ecology

The Lane Cove River rises near Thornleigh and flows generally south for about 15 kilometres (9.3 mi). Its catchment area is approximately 95.4 square kilometres (36.8 sq mi).[1]

The upper reaches are in a narrow, forested valley eroded into the North Shore Plateau. The middle reaches are impounded by a weir just upstream of Fullers Bridge. Sections of the valley are richly forested and are protected within the Lane Cove National Park, an area of 598 hectares (1,480 acres),[2] formerly a State Recreation Area. The lower reaches of the Lane Cove River, downstream from the weir near Fullers Bridge, are tidal and merge into Sydney Harbour at Greenwich and Woolwich. There are significant areas of mangrove communities along the shores.

The confluence of the river is with Scout Creek in Lane Cove National Park at Cheltenham. At North Epping, still within the confines of the national park, it is joined by Devlins Creek from the south and Terrys Creek near Macquarie Park. South–west of Killara and Lindfield, the width of the river expands, continuing south through Lane Cove River National Park, towards the suburbs of Linley Point and Riverview, before finally reaching its mouth between Greenwich Point and Woolwich, where it merges with Parramatta River and soon after becomes part of Port Jackson, more commonly known as Sydney Harbour.

Devlin Creek was named after the Devlin family, who lived in Willandra, a historical house in Ryde.

Register of the National Estate

The area surrounding the river, no more than 1 kilometre (0.62 mi) wide, is called Lane Cove National Park, and is a site of ecological importance, listed on the Australian Register of the National Estate. It contains an endangered community of fungi, significant by international standards, some species of which have still not been classified.[3]

A popular caravan park and campground known as Lane Cove River Tourist Park is located on the western side of the valley above the river.

Great North Walk

The Lane Cove River is the site of many old trails and tracks, some of which have survived from logging days. They are now used extensively for recreational purposes. Many of them have been incorporated into the Great North Walk, a long distance walking trail from Sydney to Newcastle. This trail passes along the Lane Cove River between Boronia Avenue, Hunters Hill, and Thornleigh Oval, Thornleigh.[4] On the east side of Thornleigh Oval, the trail makes use of Lorna Pass, a track built during the Depression of the 1930s to provide relief work. The pass was named after Lorna Brand, who raised money for the work.

Fairyland

From 1913 to the early 1970s, the Swan family operated a picnic area called Fairyland, which was located on the banks of the river, upstream from Epping Road. The area was originally a market garden, but the family turned it into a picnic area when they realized the commercial potential. Facilities were developed to the point where Fairyland had its own footbridge, BBQ fireplaces, boat swing, razzle dazzle ride, shelter, dance hall and wharf.[5] The area has now returned to nature and is contained within the Lane Cove National Park. The Great North Walk passes through it.

Cultural items of significance

Harry Smith was a businessman who owned land in what is now the Marsfield area. Smith created a picnic area in a section of his property he called Curzon Park, which bordered the Lane Cove River and consisted of eighty acres of bushland.[6] The picnic area has long since returned to nature, but a set of stone steps can still be seen at the top of the escarpment above the river. It is almost certain that Smith had these steps built to provide access to the picnic area. This is supported by a news item from 1899, which states that a set of stone steps went down to the picnic area.[7]

Smith also had a quarry in the area, near the present location of Talavera Road, from which he obtained the stone to build his mansion, Curzon Hall. The latter was built circa 1899 and is located at the intersection of Balaclava and Agincourt Roads. The name Curzon came from his wife's name: Isabella Curzon Webb. The building was purchased by the Vincentian Fathers in 1922 and turned into a Catholic seminary.[8] In 1983 it was acquired for business purposes and became a function centre. Curzon Hall is listed on the New South Wales Heritage Register as a site of significance.[9] Smith is remembered as a philanthropist who allowed the public to use the picnic area free of charge, and who built the public school in Marsfield. He died in 1913.

The river is known for being the site of the mysterious deaths of Dr Gilbert Bogle and Margaret Chandler on 1 January 1963. The cause of their deaths has never been established; but there is a strong theory that the two deaths may have been caused by accidental hydrogen sulphide poisoning, due to the build-up of the poisonous gas beneath the river bed that formed both naturally and by pollutants from nearby factories along the river.
