“…The Willandra Lakes, fed by a distributary of the Lachlan River, experienced oscillating lake levels consistent with seasonal fluvial activity, sufficient to fill lakes several hundred kilometres distant from their source (Bowler et al, 2012), and potentially relating to seasonal snow melt from the glaciated highlands (Kemp and Rhodes, 2010). Recent work by Dossetto et al (2010) suggests increased sediment production and reduced residence time in the southern MDB during the LGM, possibly indicating high seasonal flow.…”

“…Keilambete and the Wimmera lakes in southwestern Victoria (Chivas et al, 1985a;Chivas et al, 1986b;Chivas et al, 1986a;Jones et al, 1998;Kemp and Rhodes, 2010;Bowler et al, 2012;Kemp et al, 2012;Wilkins et al, 2012) and those presented as part of the CLIMANZ compilation (Chappell and Grindrod, 1983). Deflationary environments are more common in the case of inland lakes, particularly those which receive intermittent or no fluvial inflow, such as the highland-fed Willandra lakes within the semi-arid zone (Fig.…”

“…On the Riverine Plains, lakes fed by the major river systems were deep or overflowing (Page et al, 1994) and records from the Willandra Lakes suggest a period of high lake levels at Lakes Mungo and Arumpo just prior to 30 ka, followed by oscillating lake levels persisting after this time and throughout the LGM (Bowler, 1998;Bowler et al, 2003;McIntosh and Barrows, 2011;Bowler et al, 2012). This fluvio-lacustrine activity has been argued to represent increased runoff within the catchments in response to increased snow melt in the highland headwaters, combined with reduced vegetation cover (Kemp and Rhodes 2010).…”

“…This fluvio-lacustrine activity has been argued to represent increased runoff within the catchments in response to increased snow melt in the highland headwaters, combined with reduced vegetation cover (Kemp and Rhodes 2010). During the early last glacial period, the Willandra Lakes record shows a progressive drop in lake levels, intermittent with periods of clay deflation during what is referred to as the Upper Mungo unit (Bowler et al, 2012).…”

Dosseto, A. (2013). Climatic records over the past 30 ka from temperate Australia -a synthesis from the Oz-INTIMATE workgroup. Quaternary Science Reviews, 74 58-77.Climatic records over the past 30 ka from temperate Australia -a synthesis from the Oz-INTIMATE workgroup AbstractTemperate Australia sits between the heat engine of the tropics and the cold Southern Ocean, encompassing a range of rainfall regimes and falling under the influence of different climatic drivers. Despite this heterogeneity, broad-scale trends in climatic and environmental change are evident over the past 30 ka. During the early glacial period (∼30-22 ka) and the Last Glacial Maximum (∼22-18 ka), climate was relatively cool across the entire temperate zone and there was an expansion of grasslands and increased fluvial activity in regionally important Murray-Darling Basin. The temperate region at this time appears to be dominated by expanded sea ice in the Southern Ocean forcing a northerly shift in the position of the oceanic fronts and a concomitant influx of cold water along the southeast (including Tasmania) and southwest Australian coasts. The deglacial period (∼18-12 ka) was characterised by glacial recession and eventual disappearance resulting from an increase in temperature deduced from terrestrial records, while there is some evidence for climatic reversals (e.g. the Antarctic Cold Reversal) in high resolution marine sediment cores through this period. The high spatial density of Holocene terrestrial records reveals an overall expansion of sclerophyll woodland and rainforest taxa across the temperate region after ∼12 ka, presumably in response to increasing temperature, while hydrological records reveal spatially heterogeneous hydro-climatic trends. Patterns after ∼6 ka suggest higher frequency climatic variability that possibly reflects the onset of large scale climate variability caused by the El Niño/Southern Oscillation.
