It originates from the Eastern Ghats of Dandakaranya range in Kalahandi district and flows in a westerly direction; enters into Jagdalpur in Chhattisgarh state. It further traverses in the westerly direction and thereafter in southern direction before finally meeting Godavari River at the border of Maharashtra, Chhattisgarh and Telangana. The river during its course forms the boundary between the states of Maharashtra and Chhattisgarh at various places.
The Indravati is sometimes known as the "lifeline" of the Bastar district of Chhattisgarh, one of the greenest districts in India.
Most of the river course is through dense forests of Bastar. The river flows for 535 kilometres (332 mi) and has a drainage area of 41,665 square kilometres (16,087 sq mi).
Source and flow
The river Indravati rises at an elevation of 914 metres (2,999 ft) in the Kalahandi district of Odisha on the western slopes of the Eastern Ghats. It flows west-ward through the Kalahandi, Nabarangapur and Koraput districts for 164 kilometres (102 mi) and after forming the boundary between Odisha and Chhattisgarh states for 9.5 kilometres (5.9 mi), enters the Bastar district of Chhattisgarh. After flowing 233 kilometres (145 mi) in Chhattisgarh, it turns south and flows along the boundary of Chhattisgarh and Maharashtra for about 129 kilometres (80 mi) and joins Godavari River at the junction of the boundaries of Maharashtra, Chhattisgarh and Telangana states.
The Indravati sub-basin covers a total area of about 40,625 square kilometres (15,685 sq mi). Indravati has a catchment area of 7,435 square kilometres (2,871 sq mi) in Odisha. The length of river is about 535.80 kilometres (332.93 mi), and starting from the hills of Kalahandi, it joins the Godavari river near village Bhadrakali in Bijapur district of Chhattisgarh. It has a well-defined course from its origin to its confluence with the Godavari River. Starting in a south-east direction as a small rivulet in Odisha, it later runs in western direction through Bastar district of Chhattisgarh until it is deflected and runs north-west and then again takes a turn to the south-west. During its total course of 535.80 kilometres (332.93 mi) the river drops by 832.10 metres (2,730.0 ft). Its bed level at its junction with the Godavari River is of the order of R.L. 82.3 m compared to the level in Kalahandi from where it takes off is 914.4m.
Indravati and Sabari are interconnected naturally in Odisha area. Indravati waters overflow into the Sabari through Jaura nallah during floods.

A total of five hydroelectric projects (Kutru I, Kutru II, Nugur I, Nugur II and Bhopalpatnam) were planned on the stretch of Indravati River at various points in time. But none could see the light of the day due to ecological concerns raised in various fora.
According to Interstate Agreement as per Godavari Water Disputes Tribunal (GWDT) Report, the State of Odisha has to ensure 1.3×109 cubic metres (45,000×106 cu ft) (45 TMC) of water at the Odisha–Chhattisgarh border.
