Bueng Khong Long (Thai: บึงโขงหลง, in Thai pronounced as /bɯ̄ŋ kʰǒːŋ lǒŋ/) is a district (amphoe) of Bueng Kan province, northeastern Thailand.
Both this district and its Bueng Khong Long subdistrict are named after a reservoir south of Bueng Khong Long town. The reservoir was created in the 1980s under a royal initiative by the late-King Bhumibol Adulyadej to provide irrigation for farmers as well as to enhance biodiversity. The lake's wetlands are an important stopover point for migrating birds, and also a spawning ground for fish. Fish are a key protein source for locals.[1]
The minor district was split off from Seka district on 7 January 1986.[2] It was upgraded to a full district on 4 November 1993.[3]
Neighboring districts are (from the south clockwise): Ban Phaeng and Na Thom of Nakhon Phanom province; Seka and Bung Khla of Bueng Kan Province. To the east across the Mekong River is the Laotian province Bolikhamxai.
Bueng Khong Long district is divided into four sub-districts (tambons), which are further subdivided into 57 administrative villages (mubans).
