Lake Kezenoy-am (Lake Goluboye, Russian: Кезенойам, Голубое; Chechen: Къоьзана Iaм) is the deepest lake in the Caucasus Mountains, mostly in Chechnya but partly in Dagestan in the Russian Federation. It goes through Andiyskiy Khrebet (Andian Ridge). It is situated at an altitude of 1870 m above sea level and fills an area of 2.4 km². The maximum depth of the lake is 74 m. In winter the surface of the lake freezes and in summer the water temperature is around 5 °C. The lake water has a year-round supply of oxygen in which plankton survive. Salmo ezenami, a rare species of trout, are native only to the lake; however, their population is threatened with extinction due to the introduction of European chubs (Squalius cephalus) which consume the fry of the Salmo.
According to the regulations on land management, Dagestan owns two-thirds of the lake area. However,Archaeological findings and historical and architectural structures such as the Chechen fighting and residential towers, including unique in its medieval Chechen Castle Aldama, Gezi, sanctuaries, crypts, ancient burial grounds, one of the earliest in Chechnya mosques, many Chechen villages Kezenoi, Hoi An, Arsoy, Sadoi, Buni, Makazhoy et al., located around Kezenoyam, and the results of ethnographic expeditions reveal about the ancient settlement of the area by Chechen Taipei .

Geographic data and origins
Kezenoyam Highland Lake - the largest lake on the area of the North Caucasus, located on the border of the Vedeno district of Chechnya and Dagestan Botlikh district, on the southern slopes of the Andean mountain range, at an altitude of 1869 (1822 ) meters above sea level. surface of a lake - 2.4 km². Waters was formed by the dam of the valley two small rivers - Harsum (Alhar) and Kauha (go) . The collapse, dam the valley, there was from the southern slope of the ridge Kashkerlam, below the confluence of these rivers. The reason, most likely, it was an earthquake.
Natural Dam, located in the western part of the lake reaches a height of over 100 meters. The basin of the lake has steep slopes and flat bottom. The depth of the lake reaches 74 m . The length of the lake from north to south - 2 kilometers, and from west to east - 2.7 kilometers. Maximum width - 735 meters. The coastline - 10 kilometers. The lake is fed by flowing into it rivers and streams, as well as knocks in the most hollow of keys. The main role in the diet of the lake is a small river Harsum, which flows into the lake in its northern part, and Kauha, which flows to the east.

The water level in the lake every year varies depending on the number of outliers in its basin precipitation. The lake water is cold, the summer surface temperature does not rise above 17-18 degrees Celsius. The water temperature in the lower layers - about 7-8 degrees Celsius. In winter the lake freezes, the ice thickness in some years reached 70-80 centimeters.
Tourism and rest
