TheDaly River is a river in theNorthern Territory ofAustralia. It is part of the Daly Catchment.

The Daly River flows 354 kilometres (220 mi) from the confluence of theFlora River andKatherine River to its mouth on theTimor Sea.^[5] It is one the few major rivers in the Northern Territory that flows all year round. Sustained by groundwater, its dry-season flows are five time larger than any other river in the territory.^[6]

It is home to more than 90 species of fish. It is best known for its largebarramundi making it a popular waterway for recreational fishing. The floodwater carries baitfish which attracts predatory barramundi. The river is also home to the critically endangeredlargetooth sawfish. It also has eight different turtle species, includes the endangeredpig-nosed turtle, more than any other Australian river.^[7]

Thetraditional owners of the river and surrounding area are theWadjigiynk,Maranunngu,Malak Malak, Kamu, Warai,Nanggiwumerri,Wagiman,Wardaman,Dagoman,Jawoyn,Matngala, andYangman peoples.^[6]

Boyle Travers Finniss named the river after SirDominick Daly, theGovernor of South Australia, as the Northern Territory was at that time part ofSouth Australia.^[8] The region then lay untouched by Europeans until 1882 whencopper was discovered.

Settlement on the river is centred on theAboriginal community ofNauiyu, originally the site of aCatholicmission from 1955 to 1977,^[9] as well as the town ofDaly River itself, at the river crossing a few kilometres to the south.^[10]

The Daly River Copper Mine was established after a rich copper lode was discovered at Mt Haywood along the Daly River in 1882. Woolwonga people killed four mine workers Johannes Noltenius, John Landers, Thomas Schollert and Henry Roberts on 3 September 1884. This triggered theCoppermine massacres led by the mine manager Sachse with a police party, led byGeorge Montagu, that saw over 150 people killed, decimating the Malak-Malak and Woolwonga people.^[11] After a history of boom to bust and multiple lease turnovers the mine closed for good in 1925.^[12]

The river also supports cattle, with the Daly River Cattle Station starting up in 1985, nowTipperary Station.^[12]

The Daly River is popular location for tourism and recreational fishing due to its large barramundi.^[13] It hosts two major fishing competitions annually, the "Barra Classic" and the "Barra Nationals". Both occur just after the wet season when the flooded river is falling fast, and clear water is pouring in off the floodplains which is thought to be the best time for fishing.^[14][15]

The Daly is also the site of a proposed large-scale cotton industry harvesting up to 500 gigalitres of flood waters. This would come under the Oolloo Dolostone Aquifer Water Allocation Plan that has already been overallocated by the Northern Territory Government.^[16][6][17]

Like other rivers of thetop end, the Daly is prone to seasonal flooding. Major flood events devastated the town of Daly River in 1899 and 1957, causing widespread property damage. The largest flood event post colonisation was in 1998, when floodwaters were fed by heavy rainfall in the wake ofTropical Cyclone Les reaching a peak of 16.25 m (53.3 ft) at the Daly River Police Station gauge, the highest level recorded to date. There were also flooding events triggering evacuations in 2000, 2018, 2023 and 2024.^[18][19]
