All the most sought-after Lake Eyre FactsIMG_0156

Lake Eyre is the largest salt lake in Australia and a place that captures the imagination of many people.

Don’t forget to visit our page on Lake Eyre National Park and our Lake Eyre Travel Advice page if you’re thinking about taking a trip to this remote part of Australia.

Facts and Figures:

Here’s what everyone wants to know about Lake Eyre, like where it is, what it is, how big it is and how often does it fill up:

  • Lake Eyre is Australia’s largest salt lake
  • It’s located 647 km north of Adelaide, in the state of South Australia
  • Lake Eyre is actually comprised of 2 lakes: Lake Eyre North and Lake Eyre South
  • The lakes are connected by the Goyder Channel, which is 15 km long
  • Together, both lakes are 144km long and 77km wide
  • Lake Eyre is the lowest point below sea level on the Australian mainland (15.2m below sea level)
  • Lake Eyre is the focal point of Australia’s second largest drainage system, the Lake Eyre Basin
  • The Lake Eyre Basin covers over 1 million square kilometres
  • The Lake was named after explorer Edward John Eyre, the first European to see it in 1840
  • Lake Eyre experiences a small (1.5 m) flood every 3 years, a large (4 m) flood every 10 years and fills an average of only four times each century!

There are a few things that you’ll need to know if you want to visit.

Lake Eyre can be reached via the Oodnadatta Track. There are three places to see it:

  • At Lake Eyre South, easy access from the Oodnadatta Track via pull in bay
  • Near William Creek via the Halligan Bay Track (rough 4WD only track)
  • Near Marree via Muloorina Station and the Level Post Bay Track (rough 4WD only track)

One interesting fact about the Lake is that it’s been an important site for Arabunna and other Aboriginal people for several thousand years. Aboriginal people continue to consider the lake an important cultural site and are involved in its management today.

Even though Lake Eyre is one of the driest places in Australia, the waterways and mound springs encouraged European settlement in the 1860s.

Pastoralists had established many cattle stations in the area by the mid 1880s, although many of these were abandoned during a drought in the 1890s and early 1900s.

The largest cattle station in Australia, Anna Creek, is located on the south-eastern side of Lake Eyre.

The Lake Eyre National Park was established in 1985, whilst the Elliot Price Conservation Area was donated by Elliot Price of Muloorina Station in 1967. There is no public access to this conservation area.

Lake Eyre Water Levels

Lake Eyre’s water levels mainly depend on the annual monsoon and how much rain falls in the lake’s catchment in Queensland and the Northern Territory.

The water entering Lake Eyre comes mostly from the rivers from the northeast (in Queensland), which flow down from the Channel Country. A smaller amount of water comes down from Northern Territory from the Finke River catchment, via the Macumba River.

Generally, it takes around 6-8 weeks for water from the Channel Country to reach the lake.

Lesser amounts of water come from local rainfall. Local rainfall filled the lake in 1984 and 1989 and 2010.

However, it is the strength of the tropical monsoon that determines if water reaches the lake and how much water it will receive.

The deepest water level ever recorded in the lake was 6 metres, in 1974.

One of the more disturbing facts is that as water fills the lake, the salinity increases and causes a massive fish kill. (Yes, there are about 6 or 7 species of fish which live in the lake!).

Once the lake is full, however, it’s no more salty than the sea. As the lake dries up and the wter evaporates, its salinity increases again.

During this time Lake Eyre often appears to turn ‘pink’. This is in fact caused by a pigment found within an algae species that lives in the lake.

Current Lake Eyre Water Levels

In early 2010, massive summer rains in Queensland saw the Diamantina, Georgina and Cooper Creeks flood into the Lake Eyre Basin. This was the first time that Cooper Creek had reached Lake Eyre since 1990.

Over winter in 2010, hundred of thousands of pelicans, gulls, avocets and other waterbirds migrated to the area and began breeding.

The lake filled by mid-year, and saw many tourists visiting to see this once-in-a-lifetime event.

More recently, heavy rain  fell over western Queensland in early 2018 and the water is now flowing into the northern end of the lake. Many of the creeks in the north-east to flow towards the lake as well contributing to the water flowing towards Lake Eyre.

If you want to see this the best way to do so is by air.

  • Chuck Reed says:

    Where do the fish come from in Lake Eyre? If from inland rivers, the salinity will kill them. Are there fish eggs in the bed which stay viable for 10 years?

  • Ray Coleman says:

    Is it possible to do a day trip in to tha lake from Marree

    • Amanda says:

      Hi Ray,

      Yes it is – out through Muloorina -it will take you a couple of hours to get out there, and you will need a 4WD. Check with Lyall at the Marree Roadhouse what the track is like. His partner has been out there in the past few days, I think.

  • Wazza says:

    Where does the overflow from Lake Eyre go to. In which direction does it flow and who and what is affected?

  • john says:

    Is there water in lake eyre now end march 2017
    Will there be water comming from QLD after this cyclone down the coopers rivers.

  • Robert Breen says:

    What is the total water capacity (in mega or giga litres) of Lake Eyre when it is 100% full? I can’t find any estimates online.

  • Helen says:

    Can a caravan be taken out to the lake

  • clyde lawson says:

    is it fact or fiction that when lake eyre has water in it south australia has average winter rain fall

    • Gary says:

      Hi Clyde, I don’t think I can answer this! perhaps braver people than I might be able to respond. I have heard however from others that when there is more water inland that, obviously, more water evaporates and this has turn into rain somewhere. cheers Gary

  • June Bevan says:

    What will Lake Eyre be like early September.?

    • Amanda says:

      Hi June,

      We really can’t say! So much depends on the weather… i.e. how windy will it be, will there be more rain locally, will the temperatures continue to be waaay above average like they have this year. All these things affect the amount of water in the Lake and its rate of evaporation. There likely will be some water left, but you’ll need to take a flight to see it.

  • Linda Smith says:

    Hey Amanda! Love this article! It’s been so helpful and I love how young and fun you are! LOL ? (as the kids like to say) Can’t wait to visit lake eyre this thanksgiving! Coming down for the wine and the fun! #WAP?? #WorshipAndPray

    Love these little hashtags! ?? x

  • Abel says:

    The lake is a focal point to the largest drainage catchment area in Australia (Wikipedia.) but your article says it is the second largest.

    • Abel says:

      Why does water seem to drain toward the south pole?

      • Gary says:

        Just a coincidence, there are many examples where basins drain seaward in all directions. For example the Fitzroy basin in Queensland drains eastward towards the Pacific.

    • Gary says:

      The Murray Darling is apparently the larger drainage system. Whatever is first they are nonetheless large systems.

  • Roland Layh says:

    I’m curious to know the lowest altitude of the Kati Thanda-Lake Eyre Basin’s PERIMETER…
    ie if the basin were to fill to overflowing, where would it drain?

    • Gary says:

      Hi Roland, not sure on the actual altitudes but once Kati Thanda fills it will overflow into Lake Eyre south. To be honest I’m not sure if it has gone any further. Cheers
