Tia River /ˈtˈɑːr/ , a perennial stream of the Macleay River catchment, is located in the Northern Tablelands district of New South Wales, Australia.

A perennial stream or perennial river is a stream or river (channel) that has continuous flow in parts of its stream bed all year round during years of normal rainfall. "Perennial" streams are contrasted with "intermittent" streams which normally cease flowing for weeks or months each year, and with "ephemeral" channels that flow only for hours or days following rainfall. During unusually dry years, a normally perennial stream may cease flowing, becoming intermittent for days, weeks, or months depending on severity of the drought. The boundaries between perennial, intermittent, and ephemeral channels are not defined, and subject to a variety of identification methods adopted by local governments, academics, and others with a need to classify stream-flow permanence.

Macleay River river in New South Wales, Australia

Macleay River, an open and trained mature wave dominated, barrier estuary, is located in the Northern Tablelands and Mid North Coast districts of New South Wales, Australia.

Northern Tablelands Region in New South Wales, Australia

The Northern Tablelands, also known as the New England Tableland, is a plateau and a region of the Great Dividing Range in northern New South Wales, Australia. It includes the New England Range, the narrow highlands area of the New England region, stretching from the Moonbi Range in the south to the Queensland border in the north. The region corresponds generally to the Bureau of Meteorology forecast area for the Northern Tablelands which in this case includes Inverell although it is significantly lower in elevation.

Course and features

The river rises below Mount Grundy on the eastern slopes of the Great Dividing Range southwest of Tia, and flows generally northeast before reaching its confluence with the Apsley River, northwest of Tia. The river descends 905 metres (2,969 ft) over its 52 kilometres (32 mi) course; [2] spilling over the Tia Falls in the Oxley Wild Rivers National Park.

Great Dividing Range mountain range in the Australian states of Queensland, New South Wales and Victoria

The Great Dividing Range, or the Eastern Highlands, is Australia's most substantial mountain range and the third longest land-based range in the world. It stretches more than 3,500 kilometres (2,175 mi) from Dauan Island off the northeastern tip of Queensland, running the entire length of the eastern coastline through New South Wales, then into Victoria and turning west, before finally fading into the central plain at the Grampians in western Victoria. The width of the range varies from about 160 km (100 mi) to over 300 km (190 mi). The Greater Blue Mountains Area, Gondwana Rainforests, and Wet Tropics of Queensland World Heritage Areas are located in the range.

Tia, New South Wales Town in New South Wales, Australia

Confluence Meeting of two or more bodies of flowing water

In geography, a confluence occurs where two or more flowing bodies of water join together to form a single channel. A confluence can occur in several configurations: at the point where a tributary joins a larger river ; or where two streams meet to become the source of a river of a new name ; or where two separated channels of a river rejoin at the downstream end.

The river is transversed by the Oxley Highway.

Previously the river was known as Crimps Creek and also Crokers River which John Oxley had named this stream, in honour of the First Secretary of the Admiralty. [1]

John Oxley British explorer

John Joseph William Molesworth Oxley was an explorer and surveyor of Australia in the early period of British colonisation. He served as Surveyor General of New South Wales and is perhaps best known for his two expeditions into the interior of New South Wales and his discoveries of the Tweed River and the Brisbane River in what is now the state of Queensland.

The country above the Tia Falls is a rich grazing area used for rearing livestock. The upper parts of the Tia River have remarkable cool temperate rainforests, with unusual species such as Southern Sassafras, White Mountain Banksia and Black Olive Berry.

Grazing method of feeding in which a herbivore eats parts of low-growing grasses, forbs or algae

Grazing is a method of feeding in which a herbivore feeds on plants such as grasses, or other multicellular organisms such as algae. In agriculture, grazing is one method used whereby domestic livestock are used to convert grass and other forage into meat, milk and other products.

Livestock Domesticated animals

Livestock is commonly defined as domesticated animals raised in an agricultural setting to produce labor and commodities such as meat, eggs, milk, fur, leather, and wool. The term is sometimes used to refer solely to those that are bred for consumption, while other times it refers only to farmed ruminants, such as cattle and goats. Horses are considered livestock in the United States.

Rainforest type of forest with high rainfall

Rainforests are forests characterized by high rainfall, with annual rainfall in the case of tropical rainforests between 250 and 450 centimetres, and definitions varying by region for temperate rainforests. The monsoon trough, alternatively known as the intertropical convergence zone, plays a significant role in creating the climatic conditions necessary for the Earth's tropical rainforests.

Tia River is a general trout stream.

<i>Atherosperma moschatum</i> subsp. <i>integrifolium</i> subspecies of plant

Atherosperma moschatum subsp. integrifolium is a small evergreen tree native to the temperate rainforests of central and northern New South Wales, Australia. In 2006, it was recognised as a separate subspecies by Richard Schodde. Common names include "southern sassafras - narrow leaf form" and "blackheart sassafras".
