Fig. 6. Salinity and inflow of water for the Aral Sea. A, Total inflow to the Aral Sea during the regression and caused by diversion for irrigation purposes. B, The resulting increase in salinity; after 1990 the waters of the Large and Small Aral were separated and evolved independently of each other; the inserted maps show the decrease in area. After 2000 also the eastern and western parts of the Large Aral became separate water bodies, but both rapidly hypersalinizing. The construction of the dams that kept water in the Small Aral, had almost immediate effects. On the axis is indicated key events for the fauna in the system; further details in text. Modified and extended with new data from Plotnikov et al. (2021b).
