kati thanda–lake eyre located in deserts of central australia, in northern south australia. lake eyre basin large endorheic system surrounding lakebed, lowest part of filled characteristic salt pan caused seasonal expansion , subsequent evaporation of trapped waters. in dry season there water remaining in kati thanda–lake eyre, collecting in on 200 smaller sub-lakes within margins. lake formed aeolian processes after tectonic upwarping occurred south subsequent end of pleistocene epoch.


during rainy season rivers north-east part of lake eyre basin (in outback (south-west , central) queensland) flow towards lake through channel country. amount of water monsoon determines whether water reach lake , if does, how deep lake get. average rainfall in area of lake 100 150 millimetres (3.9 5.9 in) per year.


the −15 m (−49 ft) altitude attributed kati thanda–lake eyre refers deepest parts of lake floor, in belt bay , madigan gulf. shoreline lies @ −9 m (−30 ft). lake area of maximum deposition of sediment in lake eyre basin.


lake eyre divided 2 sections joined goyder channel. these known lake eyre north, 144 kilometres (89 mi) in length , 65 kilometres (40 mi) wide, , lake eyre south, measures 65 24 kilometres (40 15 mi). salt crusts thickest (up 50 cm (20 in)) in southern belt bay, jackboot bay , madigan gulf sub-basins of lake eyre north.


since 1883, proposals have been made flood lake eyre seawater brought basin via canal or pipeline. purpose was, in part, increase evaporation , thereby increase rainfall in region downwind of enlarged lake eyre. added rainfall has been modeled small. due basin s low elevation below sea level , region s high annual evaporation rate (between 2,500 , 3,500 millimetres (98 , 138 in)), such schemes have been considered impractical accumulation of salt deposits rapidly block engineered channel. @ rate of 1 cm (0.39 in) evaporation per day, 3 m (9.8 ft) viaduct flowing 0.5 m/s (1.6 ft/s) supply enough water create 100 km (39 sq mi) sea. if brine water not sent ocean, precipitate 90,000 long tons (91,000 t) of salt every year.
