[1][2] The Tangri river originates in the Shivalik hills on the border of Haryana and Himachal Pradesh State, and flows along the Haryana and Punjab border before meeting with the Ghaggar river at the confluence.

The combined Dangir-Markanda stream merges with the Sarsuti River in northeast Kaithal district, east of Diwana and southwest of Adoya, before joining the Ghaggar river just east of Dhandota village near Kasoli town in northwest Kaithal.

Further downstream on the banks of the Ghaggar stands an old derelict fort at Sirsa town named Sarsuti.

[4][6] This Sarsuti channel is currently being revived by the Government of Haryana as the ancient Sarasvat river.

Originating from the Morni Hills, the Tangri joins its southern tributary called the Balaiali River (which originates near the south of the Morni Hills) near Chajju Majra, south of Kharar.
