South Aral Sea Syr Darya, would be diverted in order to irrigate cotton and food crops in Kazakhstan and Uzbekistan. In 1986, due to an accelerated loss of water, the Aral Sea was split into northern and southern parts; the northern part is the current North Aral Sea. In 2007, the western basin had a salinity of 70 g/l and the eastern basin 100 g/l. Once the water level falls below the connecting channel (elevation 29 m), the salinities can be expected to diverge further. Under current conditions, the eastern basin may receive water from the Amu Darya in wet years, fluctuating in
Kyrgyzstan–Uzbekistan border Kyrgyzstan–Uzbekistan border The Kyrgyzstan-Uzbekistan border is 1,314km (816m) and runs from the tripoint with Kazakhstan to the tripoint with Tajikistan. It is Kyrgyzstan’s longest external boundary. The border starts in the north at the tripoint with Kazakhstan and then creates a ‘finger’ of Uzbek territory wedged between Kazakhstan and Kyrgyzstan; the border traverses the Pskem Mountains, with much of this area being taken up by a series of national parks (Ugam-Chatkal National Park in Uzbekistan and Besh-Aral State Nature Reserve in Kyrgyzstan). The boundary then proceeds in a roughly south-eastwards direction, traversing the Chatkal Range and the Qurama Mountains before
