Site description The site is situated 45 km southwest of the town of Karshi, on the border of reclaimed land and the desert. The length of reservoir is 14 km; average width, 5.5 km (widest point 7 km); average depth is 20.0 m (deepest point 40 m). The reservoir is fed by water from the Amudarya river through the main Karshi canal. Water quality depends on that of the Amudarya river. Water salinity is constant in the region of 0.7-0.8 g/l. The reservoir does not freeze and has limited vegetation cover. The gently sloping shores are covered with sparse arid vegetation impoverished as a result of overgrazing by cattle. Thickets of tamarisk occur in some places.

Key Biodiversity Observations carried out in the vicinity of the reservoir (steppe sites) in the last few years have revealed Chlamidotis undulata on migration and it is possible that the species also breeds. The breeding bird community of the reservoir is poor, which is connected with the instability of the hydrological regime. In winter, the situation significantly changes. In the course of two years of winter counts, 23 species of waterfowl were recorded wintering on the reservoir, including the globally endangered Aythya nyroca. Two national Red Data Book species were also recorded - Haliaeetus albicilla and Larus ichthyaetus. The number of water birds concentrated here in winter corresponds to Ramsar and IBA criteria as a site of international importance. In January 2000 and 2004, the number of waterbirds recorded were 66,698 and 57,022 respectively.

Non-bird biodiversity: The following species inhabiting desert and semi-desert areas were recorded: rodents by gerbils and Long-clawed Ground Squirrel; Muskrat inhabits areas bordering canals and collector water courses; predators by Vulpes vulpes karagan, Golden Jackal and Steppe Cat; and reptiles by Steppe Agama. Fish in the reservoir include sazan and, cat-fish. Tree-shrub vegetation in the coastal zone has almost been lost to agricultural development, collection of firewood by local residents and overgrazing by cattle. Small areas of sparse thickets of tamarisk, saltwort and Artemisia sp. can be found and Koreleniya grows in the damp depressions.

Habitats

IUCN habitat Habitat detail Extent (% of site)
Wetlands (inland)   100%

Land use

Land-use Extent (% of site)
agriculture 30%
Notes: Lands in the coastal part of the water body are used as pastures for domestic cattle. All the year round, the water body is used as the watering pond for small cattle.
fisheries/aquaculture 80%
Notes: If used for fisheries under the long-term rent, it will bring about practically non-regulated and uncontrolled catch of fish.
water management 100%
Notes: The water body is significantly affected by water management conditions. Water discharges depending on the agricultural needs reach 80%. This prevents the formation of the nesting avian fauna on the water body.
