Course and features
The river rises in the Great Dividing Range, on the southern slopes of McPherson Range, west of Mount Lindesay, and flows generally south east and north east, joined by twelve tributaries, including the Wilsons River, before reaching its mouth at its confluence with the Coral Sea of the South Pacific Ocean near between Ballina; descending 256 metres (840 ft) over its 237 kilometres (147 mi) course.
On its journey it passes through the towns of Kyogle, Casino, Coraki and Woodburn. Summerland Way is situated adjacent to much of the middle reaches of the course of Richmond River. At Ballina, the Pacific Highway crosses the river.
The catchment area of the river is estimated at 6,862 square kilometres (2,649 sq mi), which makes it the sixth largest catchment in New South Wales; and its floodplain has an area of over 1,000 square kilometres (390 sq mi).
The traditional custodians of the land surrounding the Richmond River are the Aboriginal people of the Githabul, whose territory reached north to the current city of Toowoomba and included the current towns of Tenterfield and Warwick. One of the annual rituals of the Githabul people was the movement from the mountain ranges to the coast during the winter months, when the mullet were plentiful.
Omitted by Captain James Cook when he sailed up the east coast of the Australian mainland in 1770, it wasn't until Captain Henry John Rous identified the mouth of the river in 1828 that it was discovered by Europeans. Rous entered the river and sailed about 20 miles (32 km) up river. He subsequently named the river Richmond after the fifth Duke of Richmond. Later that year the explorer Allan Cunningham reached the river by land.
The river was a major port from the 1840s until well into the 20th century. Soon after the first white settlers arrived they discovered the abundant supply of Australian Red Cedar in the Richmond Valley and immediately began logging. The river was vital in the transportation of this resource.
At the time of its discovery in 1828 and until the late 1890s the river had a treacherous mouth of shifting sand bars, and many ships and lives were lost on it. Understandably, a decision was made to construct two breakwaters to channel the river's flow and these were completed in the early 1900s. The construction of the breakwaters also led to the formation of Shaw's Bay (after sand built up behind what is now called Lighthouse or Main Beach).
With the decline of shipping as a transport mode, owing to better roads and rail, and the closing of the North Coast Steam Navigation Company (the major shipping firm of the area) in 1954, the river became less important as a port.
For boats, the river is navigable for a short way up its length, possibly as far as Casino. Wilsons River, which flows through the city of Lismore and is a major tributary of the Richmond, is navigable at least as far as Boatharbour, approximately 12 kilometres (7.5 mi) upstream from Lismore.
The freshwater reaches of the Richmond River once supported the endemic Richmond River Cod, similar to Murray Cod and possibly a subspecies of Eastern Freshwater Cod. Unfortunately this unique native fish became extinct between the 1930s and 1950s due to habitat degradation and gross overfishing, including with dynamite during the building of the local railway line. The endangered Oxleyan Pygmy Perch has been recorded from the river.
