Umngot River is a major south-flowing river originating from the eastern part of the Shillong Peak near a village called Smit in East Khasi Hills of Meghalaya. Starting from an altitude of about 1,800 m above sea level, it forms the boundary between East Khasi Hills District and Jaintia Hills District and emerges through a gorge at Shnongpden. This 82 km long river irrigates (including its tributaries) over 800 sq km and is famous for angling.
Umngot continues in its less turbulent form to flow by the fine gorge near Dawki and finally enters into the plains of Bangladesh. Dawki Bridge, the motorable suspension bridge built across Umngot, forms the link of National Highway 40 (Guwahati-Shillong-Dawki Road).
