The Clear River , also Lô or Panlong (Vietnamese Sông Lô , French Rivière Claire , Chinese 盘龙江 , Pánlóng Jiāng ), is a tributary of the Red River in southern China and northern Vietnam .

In addition to the Black River , it is one of the two main tributaries of the Red River and the largest left-hand, i.e. northern, tributary. It is approximately 470 kilometers long and has a catchment area of ​​approximately 39,000 km².

course

It rises in the district Yanshan of Autonomous Prefecture Wenshan in the Chinese province of Yunnan ; its main source river is the dammed jiayi . From here the river flows south. It crosses the district capital of Wenshan before it is dammed in Malipo County by the Malutang Dam . A few kilometers downstream it reaches the Vietnamese border.

In Hà Giang , the northernmost city of Vietnam and capital of the province of the same name , the Sông Miệm (Chinese: Babu ) flows into it . In Vĩnh Tuy (Bắc Quang) the Sông Con merges into the Clear River, which at this point reaches the province of Tuyên Quang . North of the provincial capital of the same name , the Clear River grows strongly due to the confluence of the Sông Gâm, which is similarly rich in water .

In the following province of Phú Thọ , the Sông Chảy flows into Đoan Hùng (which previously formed the Thác-Bà reservoir ). In its last section, the Clear River represents the border to the province of Vĩnh Phúc . Immediately before its end, the Sông Phó Đáy merges into it. The Clear River finally flows into the Red River near the city of Việt Trì - about 50 kilometers before Hanoi and 10 kilometers after the mouth of the Black River.

history

During the Indochina War , the river valley was fiercely fought over between the French and Việt Minh . The French attacked the Việt Minh logistics networks along the river twice ( Operation Léa in October 1947, Opération Lorraine at the end of 1952) with land troops, air support and Dinassaut river combat units combined, but were unable to destroy the guerrilla structures. The defense of the first attack in 1947 was glorified by the composer Văn Cao in the popular song Trường ca Sông Lô ("Epic of the Lô River").

Further fighting - this time on the upper reaches of the river - took place during the Sino-Vietnamese border war in 1979 .
