Title: Lake Eyre
Content:  In late 2015, water began flowing into Lake Eyre following heavy rain in the north-east of the state.
Title: Lake Eyre
Content:  Typically a 1.5 m flood occurs every three years, a 4 m flood every decade, and a fill or near fill a few times a century. The water in the lake soon evaporates, with a minor or medium flood drying by the end of the following summer. Most of the water entering the lakes arrives via Warburton River. In strong La Niña years, the lake can fill. Since 1885, this has occurred in 1886–1887, 1889–1890, 1916–1917, 1950, 1955, 1974–1977, and 1999–2001, with the highest flood of 6 m in 1974. Local rain can also fill Kati Thanda–Lake Eyre to 3 –, as occurred in 1984 and 1989. Torrential rain in January 2007 took about six weeks to reach the lake but only placed a small amount of water into it. When recently flooded, the lake is almost fresh, and native freshwater fish, including bony bream (Nematolosa erebi), the Lake Eyre Basin sub-species of golden perch (Macquaria ambigua) and various small hardyhead species (Craterocephalus spp.) can survive in it.
Title: Eyre River (New Zealand)
Content:  The Eyre River is a river in the Canterbury region of New Zealand. It arises in the Puketeraki Range and flows south-east into the Waimakariri River near Christchurch International Airport. The connection with the Waimakariri is via a diversion channel running south-west, replacing the Eyre's original easterly flow. The river is named after Edward John Eyre, the Lieutenant-Governor of New Munster from 1848 to 1853. The river rarely carries surface water, due to the unreliability of the easterly rains which feed it.
Title: Lake Eyre
Content:  In late March 2019, floodwaters began arriving as a result of torrential rains in northern Queensland in January. In the past, the water had taken anywhere from three to 10 months to reach the lake, but this time it arrived in two. The first flooding would be closely followed by another surge, following rains produced by Cyclone Trevor. Traditional owners and graziers agree that it is essential that the river run its course and should not be harvested during floods, as any interference in the natural systems could damage the ecosystem.
Title: Lake Eyre basin
Content:   During years of especially high rainfall, all the riverbeds in this vast, mostly flat, arid and semi-arid area lead inland (not towards the sea) towards Lake Eyre in central South Australia. Lake Eyre itself lies approximately 16 m below sea level, and usually contains only salt. In flood years, it fills and, for a short time, undergoes a period of rapid growth and fertility: long-dormant marine creatures multiply and large flocks of waterfowl arrive to feed and raise their young before the waters evaporate once more. The annual mean runoff in the Lake Eyre Basin is lowest of any of the world's major drainage basins.

In extreme events, water from the Finke River flows into the Macumba River, which empties into Lake Eyre, a total distance from headwater streams of around 750 km. Major tributaries include Ellery Creek, and the Palmer and Hugh Rivers. The Georgina River system originates on the Barkly Tableland, near the Northern Territory-Queensland border, north-west of Mount Isa and not far south of the Gulf of Carpentaria. In this relatively humid northern area, rainfall can be as high as 500 mm per year and evaporation as low as 2.4 m. The Georgina flows through innumerable channels leading south through 
Title: Eyre Creek (Lake Eyre basin)
Content:  Eyre Creek is a tributary of the Warburton River. It flows from the western southwest corner of Queensland into the northeastern corner of South Australia. Eyre Creek is fed by the Georgina River and Burke River in the vicinity of Marion Downs Station. The confluence of Eyre Creek and the Diamantina River is the source of the Warburton River.

Content:  of the creeks and rivers in the Lake Eyre Basin are permanent: they flow only after heavy rain – a rare to very rare event in the arid interior of Australia. Average annual rainfall in the area surrounding Lake Eyre is 125 mm, and the pan evaporation rate is 3.5 m. Annualised average figures are misleading: since 1885 annual rainfall over the 1100000 km2 of the Lake Eyre Basin has ranged from about 45 mm in 1928 to over 760 mm in 1974. Most of the water reaching Lake Eyre comes from the river systems of semi-arid inland Queensland, roughly 1000 km to the north.

The high rainfall in summer 2010 sent flood water into the Diamantina, Georgina and Cooper Creek catchments of the Lake Eyre basin, with the Cooper Creek reaching the lake for the first time since 1990. The higher rainfall prompted many different birds to migrate back to the area for breeding. Heavy local rain in early March 2011 in the Stuart Creek and Warriner catchments filled Lake Eyre South, with Lake Eyre North about 75 per cent covered with water firstly from the Neales and Macumba Rivers, and later from the Warburton River.

Cooper Creek spreads out into a vast area of meandering ephemeral channels, making its way roughly south into the far south-west corner of Queensland before turning due west into South Australia towards Lake Eyre. It takes almost a year for water to reach Lake Eyre from the headwaters. In most years, none does: it is absorbed into the earth, goes to fill channels and the many permanent waterholes, or simply evaporates. Water from Cooper Creek reached Lake Eyre in 1990 and then not again until 2010.

Question: where does the water come from to fill lake eyre?
Answer: Warburton River.
