Tarim River
In 1952 the terminal lake then shifted to Taitema Lake when the Tarim River and Konque River were separated through human intervention, and Lop Nur dried out again by 1964. In 1972, the Great West Sea Reservoir ("Daxihaizi", 大西海子) was built at Tikanlik, water supply to the lake was cut off, and all the lakes for the most part then dried out, with only small seasonal lakes forming in local depressions in Taitema. The loss of water to the lower Tarim River Valley also led to the deterioration and loss of poplar forests and tamarix shrubs that used to be extensively distributed along the lower Tarim River Valley forming the so-called "Green Corridor". In 2000, in an effort to prevent further deterioration of the ecosystem, water was diverted from Lake Bosten in an attempt to fill the Taitema Lake. The Taitema Lake however had shifted westwards during the past 40 years due in part to the spread of the desert. Another cause of the destabilization of the desert has been the cutting of poplars and willows for firewood; in response, a restoration project to reclaim the poplar forests was initiated.
