The Warrego River is a river in eastern Australia .

geography

It rises in the southwest of the state of Queensland and flows into the Darling River in the northwest of New South Wales . It is the northernmost tributary of the Darling River.

The river flows west from its source in Carnarvon National Park and then turns south-west until it flows into the Darling River below Bourke . The main tributaries of the Warrego River are the Nive River and the Langlo River .

The towns of Augathella , Charleville , Wyandra and Cunnamulla are on the banks of the river. Cunnamulla is the only one of these settlements flood walls and is thus protected against flooding.

Tributaries

Most of the catchment area of ​​the Warrego River is too dry for grain cultivation and has only sporadic rainfall of 350 to 500 mm per year. The natural vegetation consists of grassland on the more fertile clay soils and bushes on the less fertile red soils. The land is mainly used as grazing land for sheep and cattle; Irrigation for the cultivation of grain does not allow the seasonally strongly differing water level of the river. The Warrego River has only irregular water. It does dry out for years, and significant amounts of water only reach the Darling River in particularly wet years when La Niña rules.

Drains

Below Wyandra the river forms a series of branches. In the event of flooding, Widgeegoara Creek , Kudnapper Creek and Noorama Creek drain water into Nebine Creek , a tributary of the Culgoa River . The Cuttaburra Creek connects the Warrego River with the Paroo River via a distribution system of flood channels and wetlands . The Irrara Creek arm flows into Kerribee Creek , which flows through a series of wetlands before flowing into Utah Lake .

Floods

When the La Niña weather phenomenon occurs, flooding on the Warrego River is usually the result. There were major floods in this context in 1950, 1954 to 1956, 1971, 1973, 1998 and 2008. The flood, which caused most of the destruction, had nothing to do with this weather phenomenon. In April 1990, as a result of two extremely strong trough weather conditions around Easter in Cunnamulla, over 400 mm of rain fell within just two weeks, which corresponded to "more than a complete annual amount of rain in more than 60% of the years". The river, like almost all tributaries of the Darling River, reached nearly a record high and the cities of Augathella and Charleville were devastated. In Charleville they measured a high of 8.54 meters.

fauna

The Warrego River is one of the few rivers in which the tigerfish , Bidyanus bidyanus ( English silver perch ) spawns in the wild. The codfish Macquaria ambigua (golden perch) and Maccullochella peelii (Murray cod) can also be found in the river. The 500 km² Carnarvon Station , once a huge ranch at the source of the river, was bought by the Australian Bush Heritage Fund in 2001 to protect endangered bird and other animal species.

Surname

Warrego is an Aboriginal word and means "sand river" in German - two warships of the Royal Australian Navy were named after the river " HMAS Warrego ".
