The Thanwar River joins the Wainganga at the Nainpur Forest Range, at the border of the Seoni District and Mandla District, before the Dhuty Dam on the Wainganga. It originates from the forest of Chiraidongri in the Mandla District. There is a medium-sized dam at the village of Bejegaon on the bank of this river, which opened in 1980. River water stored in the dam is used to irrigate the farmland of 50 villages. The Halon River and the Chakor River (catchment from Nainpur Forest Range) are some of the well-known tributaries to this small, fully utilized river. Geographically, this river misses a few miles due to a Satpura foothill to become the Narmada's first major tributary. The main towns on this tributary are Nainpur and Pindrai. The river has been in recreational use since ancient times, as it was on the route of pilgrimage from South to North India. The village Jhulpur, on the bank of this river, was a stoppage and temple town. The major bridge over the river is at the town Pindrai by Indian Railway (Jabalpur-Gondia rail track).
