This species has a restricted linear range and a small population. It is highly tolerant of human presence, and its habitat is not particularly vulnerable to human-induced changes. However, the many dams currently proposed for the Mekong, particularly those on sections where the river has a low gradient, have the potential to disrupt long stretches of its riverine range by flooding the river channel. Its small to moderately small population is therefore projected to undergo a moderately rapid decline over the next three generations and it is thus classified as Near Threatened.
