Floods

Typically a 1.5 m (5 ft) flood occurs every three years, a 4 m (13 ft) 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 (20 ft) in 1974. Local rain can also fill Kati Thanda–Lake Eyre to 3–4 m (9.8–13.1 ft), 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.
