Garanohur[1][2] (Azerbaijani: Qaranohur - from Azerbaijani gara - "black"[3] and nour, nohur - "lake", "reservoir", "swamp"[4]) is an alpine lake located in the Ismayilli district of Azerbaijan (8 km northeast of the city of Ismayilli), at an altitude of about 1520 m above sea level, in the basin of the Garanohurchay river, in the Greater Caucasus.

[5] According to the director of the Ismayilli Tourist Information Centre S. Suleymanov, the lake Garanohur is one of the places for future tourism in the region.

As a result of the study, different durations of rise and fall of water temperature during the day were found in the lake.

Thus, the authors found that with distance from the coast, the water temperature in the surface layer decreases, and the amplitude ranges from 27.7 °C to 18.0 °C.

[8] In Garanohur, with distance from the shore, an increase in transparency is found, which reaches its maximum in the middle of the lake.
