The Kaban Lakes ( tt-Cyrl, Кабан күле; ) are a system of lakes in Kazan, Republic of Tatarstan, Russia that includes Nizhny (Blizhny) Kaban, Verkhny Kaban, and Sredny Kaban. With a combined area of , they comprise the biggest lake in Tatarstan. The lakes are connected with the Kazanka River by the Bolaq channel and a subterranean channel from Bolaq-Kazansu.

Karst
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions. Subterranean drainage may limit surface water, with few to no rivers or lakes. However, in regions where the dissolved bedrock is covered (perhaps by debris) or confined by one or more superimposed non-soluble rock strata, distinctive karst features may occur only at subsurface levels and can be totally missing above ground. The study of ''paleokarst'' (buried karst in the stratigraphic column) is important in petroleum geology because as much as 50% of the world's hydrocarbon reserves are hosted in carbonate rock, and much of this is found in porous karst systems. Etymology The English word ''karst'' was borrowed from German in the late 19th century, which entered German much earlier ...
