Originally the area was covered by a large swamp, which was flooded in 1930 with the building of a dam to improve fishing.

This is the only known site for the white-eyed river martin which used to winter there, but has not been seen since 1980, and may be extinct.^[1]

Once, the Siamese tiger perch was considered the most iconic fish species here, so much so that people used to say, "If anyone comes to Bueng Borapet and doesn't eat this fish, it's as if they've never arrived." But now, it has likely become completely extinct in Bueng Boraphet due to overfishing, both for consumption and for the ornamental fish trade.^[2]

A near-threatened species, the marsh grassbird, was first discovered in Thailand here in early December 2019.^[3]

One hundred and six square kilometres of the lake were declared a non-hunting area in 1975. In 2000 it was designated a wetland of international importance by the Thai government.^[4]
