In the 1970s the rate nearly tripled to 50–60 cm (20–24 in) per annum, and in the 1980s to 80–90 cm (31–35 in) per annum. The amount of water taken for irrigation from the rivers doubled between 1960 and 2000. In the first half of the 20th century prior to the irrigation, the sea's water level above sea level held steady at 53 m.
In the Messinian salinity crisis (also referred to as the Messinian event, and in its latest stage as the Lago Mare event) the Mediterranean Sea went into a cycle of partial or nearly complete desiccation (drying-up) throughout the latter part of the Messinian age of the Miocene epoch, from 5.96 to 5.33 Ma (million years ago).
Based on the erosion features preserved until modern times under the Pliocene sediment, Garcia-Castellanos et al. estimate that water rushed down a drop of more than 1,000 metres (3,300 ft) with a maximum discharge of about 100 million cubic metres per second (3.5 billion cubic feet per second), about 1,000 times that of the present-day Amazon ...

Water levels at Lake Titicaca – the highest navigable lake in the world and South America’s largest – are dropping precipitously after an unprecedented winter heat wave. The shocking decline ...
During the 1970s, the expansion of irrigation projects had begun to disrupt the flow of water to the marshes; by the early 1980s, it was evident that these had significantly affected water levels. [10] Part of the Hammar Marsh was also drained in 1985 during efforts to prepare the area for oil exploration. [11]
Salt deposits along the eastern shore of the Salton Sea. The water of the Salton Sea has a salinity of 44 grams of salt per liter, greater than that of the Pacific Ocean (35 g/L). [81] The lack of an outflow means the Salton Sea does not have a natural stabilization system; it is very dynamic.
