An endorheic basin (also endoreic basin or endorreic basin) is a limited drainage basin that normally retains water and allows no outflow to other external bodies of water, such as rivers or oceans, but converges instead into lakes or swamps, permanent or seasonal, that equilibrate through evaporation.wikipedia

Caspian Sea

CaspianCaspian regionCaspian Sea basin
Endorheic water bodies include some of the largest lakes in the world, such as the Caspian Sea, the world's largest saline inland sea.
It is an endorheic basin (a basin without outflows) located between Europe and Asia, to the east of the Caucasus Mountains and to the west of the broad steppe of Central Asia.

Open and closed lakes

exorheicopen lakeclosed lake
Endorheic regions, in contrast to exorheic regions, which flow to the ocean in geologically defined patterns, are closed hydrologic systems.
Endorheic basins fall into the category of endorheic or closed lakes, wherein waters do not drain into the ocean, but are reduced by evaporation, and/or drain into the ground.

Endorheic lake (sink)

playasinkplayas
These endorheic watersheds (containing water in rivers or lakes that form a balance of surface inflows, evaporation and seepage) are often called terminal lakes or sink lakes.
An endorheic lake, or sink lake, is a collection of water within an endorheic basin, or sink, with no visible outlet.

Drainage basin

watershedbasincatchment area
An endorheic basin (also endoreic basin or endorreic basin) is a limited drainage basin that normally retains water and allows no outflow to other external bodies of water, such as rivers or oceans, but converges instead into lakes or swamps, permanent or seasonal, that equilibrate through evaporation.
In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground.

Black Sea

BlackEuxinePontus Euxinus
The Black Sea was likely such a lake, having once been an independent hydrological system before the Mediterranean Sea broke through the terrain separating the two.
During geological periods when this hydrological link wasn't present, the Black Sea was an endorheic basin, operating independently of the global ocean system (similar to the Caspian Sea nowadays).

A lake may be endorheic during dry years and can overflow its basin during wet years, e.g., the former Tulare Lake.
The lake was part of a 13670 mi2 partially endorheic basin, at the south end of the San Joaquin Valley, where it received water from the Kern, Tule, and Kaweah Rivers, as well as from southern distributaries of the Kings.

Base level

River Mouthbaseleveldischarges into it
Endorheic basins constitute local base levels, defining a limit of erosion and deposition processes of nearby areas.
Base levels may be local when large landmasses are far from the sea or disconnected from it, as in the case of endorheic basins.

Salt lake

Over time this input of erosion products can cause the endorheic lake to become relatively saline (a "salt lake").
Salt lakes form when the water flowing into the lake, containing salt or minerals, cannot leave because the lake is endorheic (terminal).
