Bosten Lake(traditional Chinese:BácTưĐằngHồ;simplified Chinese:Bác tư đằng hồ;pinyin:Bósīténg Hú,Uyghur:باغراش كۆلى/Бағраш Көли/Baghrash Köli / Baƣrax Kɵli,Chagatai:Bostang) is a freshwater lake on the northeastern rim of theTarim Basin,about 20 km (12 mi) east ofYanqiand 57 km (35 mi) northeast ofKorla,Xinjiang,China in theBayin'gholin Mongol Autonomous Prefecture.Covering an area of about 1,000 km2(390 sq mi) (together with adjacent small lakes), it is the largest lake inXinjiangand one of the largest inland freshwater lakes in China.[1]Bosten lake receives water inflow from a catchment area of 56,000 km2(22,000 sq mi).[2]
The lake's Mongol, Uyghur and Chinese names are sometimes rendered asBosten Hu,Bagrax-hu,Bagrasch-köl,Baghrasch köl,Bagratsch-kul,Bositeng LakeorBositeng Hu.
TheKaidu Riveris the most important tributary to Lake Bosten, accounting for about 83% of its water inflow,[1]other significant tributaries are the Huangshui Ditch (Chinese:Hoàng thủy câu), the Qingshui River (Thanh thủy hà), and Wulasite River (Ô lạp tư đặc hà).[3]
An active fishery exists on the lake. Until the early 1970s, two cyprinid species,Schizothorax biddulphiandAspiorhynchus laticeps,the latter of which isendemicto Bosten Lake and theYarkand River,were responsible for 80 percent of the annual catch.[4]During the years 1962 to 1965, various carp species (bighead,black,silver,grass,common,andcrucian carp) wereintroducedinto the lake.[4]In the 1970s, these species become major targets of the fishing activities.[4]Since 1978, the introducedEuropean perchhas been the dominating species in the catches from Bosten Lake.[4]
