To fill the Caspian basin to a level of more than 50 metres (160 ft) would require as much as 70,000 km 3 of water, equivalent to 200 years of river discharge into the Caspian Sea. Water flowed through the Manych Spillway (250 to 1,000 km 3 per year) and some (more than 100 km 3 per year) was lost through evaporation.
The water body lends its name to the nearby city of Garabogaz. The name was originally applied to the narrow strait which connects the gulf to the Caspian Sea. Because the water in the strait, termed a "throat" (Turkmen: bogaz), was darker than the water on either side, it was termed "dark" or "black" (Turkmen: gara), hence garabogaz. Over time ...

The Caspian Sea is the world's largest inland body of water, described as the world's largest lake and usually referred to as a full-fledged sea. [2] [3] [4] An endorheic basin, it lies between Europe and Asia: east of the Caucasus, west of the broad steppe of Central Asia, south of the fertile plains of Southern Russia in Eastern Europe, and north of the mountainous Iranian Plateau.
The Caspian's water levels, which have fluctuated sharply during the last century, have been falling since the mid 1990s, scientific studies have found. ... discussed with Russian President ...
The Ogallala Aquifer (oh-gə-LAH-lə) is a shallow water table aquifer surrounded by sand, silt, clay, and gravel located beneath the Great Plains in the United States. As one of the world's largest aquifers, it underlies an area of approximately 174,000 sq mi (450,000 km 2) in portions of eight states (South Dakota, Nebraska, Wyoming, Colorado, Kansas, Oklahoma, New Mexico, and Texas).

A graph shows the groundwater level and sea level changes with respect to the tide on a small island in Portugal. The solid line represents the sea level change in the estuary and the dotted line is date from a piezometer that installed 50 m apart from the coastal line. It shows a time lag between the sea tide and the tide of groundwater.
The Sea of Azov rose so high that it overflowed into the Caspian Sea. [dubious – discuss] The rise was extremely rapid and the Caspian basin could not contain all the floodwater, which flowed from the northwest coastline of the Caspian Sea, through the Kuma-Manych Depression and Kerch Strait into the Black Sea basin. By the end of the ...
