Indian Rivers for Exams: Origins, Tributaries and Dams in One Place
Quick revision of Indian rivers: where each rises, where it flows, its tributaries, dams and nicknames, plus common exam traps.

River questions are among the most common in Indian geography. They usually ask one of four things: where a river rises, where it ends, which river it joins or which dam stands on it. This page puts all four together.
Himalayan rivers
These rivers are fed by snow as well as rain, so they flow all year.
| River | Rises at | Key facts |
|---|---|---|
| Ganga | Gangotri glacier (as the Bhagirathi) | Bhagirathi + Alaknanda meet at Devprayag; ends in the Sundarbans delta |
| Yamuna | Yamunotri glacier | Joins the Ganga at Prayagraj; Chambal and Betwa are its tributaries |
| Brahmaputra | Near Mansarovar, Tibet (Tsangpo) | Enters India in Arunachal Pradesh; Majuli island in Assam |
| Indus | Near Mansarovar, Tibet | Flows through Ladakh into Pakistan |
| Sutlej | Rakas Tal, Tibet | Enters India at Shipki La; Bhakra Dam |
| Kosi | Nepal Himalaya | “Sorrow of Bihar” because of floods |
Ganga tributaries: from the north (left bank) the Ghaghara, Gandak and Kosi come down from the Himalaya. From the south (right bank) the Son flows up from the Amarkantak plateau. This left/right split is a favourite trap.
Peninsular rivers
These depend on the monsoon, so many shrink in the dry season.
East-flowing (into the Bay of Bengal, forming deltas)
| River | Rises at | Key facts |
|---|---|---|
| Godavari | Trimbakeshwar, Maharashtra | Longest peninsular river: “Dakshin Ganga” |
| Krishna | Mahabaleshwar, Maharashtra | Tributary Tungabhadra; Nagarjuna Sagar Dam |
| Kaveri | Talakaveri, Karnataka | Delta in Tamil Nadu; Krishna Raja Sagar and Mettur dams |
| Mahanadi | Sihawa, Chhattisgarh | Hirakud Dam in Odisha |
| Damodar | Chota Nagpur plateau | “Sorrow of Bengal”; Damodar Valley Corporation (1948) |
West-flowing (into the Arabian Sea, forming estuaries)
| River | Key facts |
|---|---|
| Narmada | Rises at Amarkantak; flows through a rift valley; Sardar Sarovar Dam |
| Tapi | Rises near Multai (Madhya Pradesh); reaches the sea near Surat |
| Sharavathi | Forms Jog Falls in Karnataka |
| Mandovi | Forms Dudhsagar Falls in Goa |
Memory tip: Narmada and Tapi are the two big rivers that flow west; almost every other large peninsular river flows east.
Lakes worth remembering
| Lake | State | Why it’s asked |
|---|---|---|
| Chilika | Odisha | Largest brackish-water lagoon |
| Pulicat | Andhra Pradesh – Tamil Nadu | Second-largest lagoon; Sriharikota lies beside it |
| Wular | Jammu and Kashmir | Largest freshwater lake |
| Sambhar | Rajasthan | Largest inland salt lake |
| Loktak | Manipur | Floating phumdis; Keibul Lamjao National Park |
| Vembanad | Kerala | Longest lake |
Common traps
- Mixing up origins: the Mahanadi rises in Chhattisgarh, not Odisha; the Kaveri rises in Karnataka, not Tamil Nadu.
- “Sorrow” rivers: Kosi = Bihar, Damodar = Bengal.
- Tributary of what? The Chambal joins the Yamuna (not the Ganga directly); the Tungabhadra joins the Krishna (not the Kaveri).
- Indus Waters Treaty (1960): brokered by the World Bank; the eastern rivers (Ravi, Beas, Sutlej) went to India.
