Site description Karakyr lake system is situated in the SW Kyzylkum desert 30 km to the N of Gazly town and 120 km to the NW of Bukhara town. Nearby there are some large hills with the same name. Karakyr was created in the 1970s and consists of two large wastewater lakes and a large area of floodplain located along the collector channel supplying the lakes. The lakes have open water areas surrounded by reed. Seepage and flooding of the sandy desert surrounding the lakes and floods is resulting in the growth of grassy vegetation and the sands are becoming fixed. The water supply of lakes is excess water from the Northern collector. The main period of inflows is in March-April. Karakyr lakes system consists of three separate lakes: Big Karakyr, Small Karakyr and Aquarium. The general area (with a buffer zone) is about 50,000 ha. The maximal depth is 4.0-5.0 m (10-15 % of all area), the average depth is 2.3-3.0 m (65-75 %). In summer due to the high rate of evaporation and a reduction of water inflows most of the reservoir (40-50 %) dries up and there is eutrophication. The bottom of the lake is basically firm but there are oozy sediments in some areas. The general mineralization is rather high: from 5,360 mg/l in winter-spring up to 12,842 mg/l in summer-autumn. Although only a few sites have been formally proposed under the A3 biome-restricted criteria (for biome CA04b Eurasian Desert and Semi-desert), many of the IBAs in the Kyzylkum Desert region support populations of biome-restricted species and, effectively, form a network of sites throughout the area.
