Kuwana River, also known as Kuano, originates as Tenus Nala in the eastern part of Bahraich District
and enters the Gonda District
, and flows through the center of the district.
Kuwana River then enters Basti District and traverses through the northern border and is fed by two small streams - Jadha Nala and Pindariya Nala. Kuwana finally merges with the Ghaghra River at Gorakhpur.
