The rate of water-level rise during the EEI may be inferred from the duration of the epoch, estimated at five to six hundred years. Assuming an equal length of the phases of rising, high water and subsiding (150 to 200 years each), the sea level would rise by 180–190 metres (590–620 ft) at a rate of at least one meter per year.
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).

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 ...

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 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 maximum water depth of the lagoon in spring and in the western areas of the lagoon reaches 2.5 meters, which varies due to the fluctuations of the water level of the Caspian Sea. • 9.53%: forest and pasture • 2.33%: Agricultural lands • 7.8%: wetlands, dams and pools • 7.3%: areas used privately by people.

Over geological timescales, changes in the shape of the oceanic basins and in land/sea distribution affect sea level. In addition to eustatic changes, local changes in sea level are caused by the earth's crust uplift and subsidence. Over geologic time sea level has fluctuated by more than 300 metres, possibly more than 400 metres.
