Indian Geography — States, Capitals and Rivers
Free study material · concepts, shortcuts & solved questions
Why This Chapter Matters
Questions on Indian states, their capitals, and river systems appear in almost every SSC GD and RPF Constable General Studies paper. Examiners like to test this topic because it is factual, unambiguous, and easy to frame as a one-line question — "Which river is the Baigul a tributary of?" or "What is the capital of Nagaland?" This chapter gives you a complete, exam-ready reference for the political map of India and the country's major river systems, along with the facts that get asked most often.
States and Union Territories of India
India currently has 28 states and 8 Union Territories, a structure that took its present shape after the reorganisation of the erstwhile state of Jammu and Kashmir in August 2019, which came into effect on 31 October 2019. Jammu and Kashmir was reconstituted as a Union Territory with a legislature, and Ladakh was carved out as a separate Union Territory without a legislature. Before that, Telangana had been created out of Andhra Pradesh in June 2014, making it the newest state of the Indian Union.

- Uttar Pradesh is the most populous state; Sikkim is the least populous state.
- Only three states have official bicameral legislatures with a Legislative Council in addition to the Assembly on a regular basis among the larger states: Uttar Pradesh, Bihar, Maharashtra, Karnataka, and Andhra Pradesh currently maintain Legislative Councils.
- Delhi, Jammu and Kashmir, and Puducherry are Union Territories that have their own Legislative Assemblies, unlike the other UTs.
- Chandigarh is administered directly by the Union Government and also serves as the capital of both Punjab and Haryana.
- India shares land borders with seven countries: Pakistan, China, Nepal, Bhutan, Bangladesh, Myanmar, and Afghanistan (a short stretch near Pakistan-occupied Kashmir).
- Gujarat has the longest coastline among Indian states, followed by Andhra Pradesh and Tamil Nadu.
- Madhya Pradesh currently has the most number of neighbouring states bordering it.
Major River Systems of India
Indian rivers are broadly classified into two categories: Himalayan rivers, which are perennial because they are fed by snowmelt as well as rainfall, and Peninsular rivers, which are largely rain-fed and seasonal. This distinction is a favourite examiner trick — always check whether a river originates in the Himalayas or the Deccan Plateau before answering.
The Ganga System
The Ganga originates at Gangotri glacier in Uttarakhand, at a point called Gaumukh, where the stream is known as the Bhagirathi. It is joined by the Alaknanda at Devprayag, after which the combined stream is called the Ganga. The river flows through Uttarakhand, Uttar Pradesh, Bihar, Jharkhand, and West Bengal before entering Bangladesh, where it is known as the Padma. It finally drains into the Bay of Bengal, forming the Sundarbans delta, the largest delta in the world, jointly with the Brahmaputra.
Major tributaries of the Ganga include the Yamuna, Ghaghara, Gandak, Kosi, Son, Chambal, and Betwa. The Yamuna, itself originating from the Yamunotri glacier, is the largest tributary of the Ganga and meets it at Prayagraj (Allahabad), a confluence known as the Triveni Sangam (with the mythical Saraswati as the third stream).
The Brahmaputra System
The Brahmaputra originates as the Tsangpo in Tibet, near Mansarovar Lake, and enters India in Arunachal Pradesh, where it is called the Siang or Dihang. It becomes the Brahmaputra after being joined by the Dibang and Lohit rivers in Assam. It flows through Assam and enters Bangladesh, where it is called the Jamuna, eventually joining the Ganga before reaching the Bay of Bengal. It is unusual among major Indian rivers for having a masculine name and for forming Majuli, the largest river island in the world, in Assam.
The Indus System
The Indus originates near Lake Mansarovar in Tibet and flows through Ladakh before entering Pakistan. Its major tributaries in India include the Jhelum, Chenab, Ravi, Beas, and Sutlej — the five rivers that give Punjab its name (Punjab means "land of five rivers"). Although most of its course lies in Pakistan today, the Indus Valley Civilisation, one of the world's oldest urban civilisations, developed along its banks.
Peninsular Rivers
Peninsular rivers rise in the Western Ghats or the central highlands and mostly flow eastward into the Bay of Bengal, except for the Narmada and the Tapi, which flow westward into the Arabian Sea through rift valleys.
| River | Origin | Outflow | Key Facts |
|---|---|---|---|
| Narmada | Amarkantak, Madhya Pradesh | Arabian Sea (Gulf of Khambhat) | Flows through a rift valley; forms the traditional boundary between North and South India |
| Tapi (Tapti) | Satpura Range, Madhya Pradesh | Arabian Sea (Gulf of Khambhat) | Second major west-flowing river |
| Godavari | Trimbakeshwar, Nashik, Maharashtra | Bay of Bengal | Longest Peninsular river; called Dakshin Ganga |
| Krishna | Mahabaleshwar, Maharashtra | Bay of Bengal | Second longest Peninsular river |
| Kaveri (Cauvery) | Talakaveri, Karnataka | Bay of Bengal | Flows through Karnataka and Tamil Nadu; subject of a long-running water dispute |
| Mahanadi | Sihawa, Chhattisgarh | Bay of Bengal | Hirakud Dam, one of the longest dams in the world, is built on it |

A Short History of State Reorganisation
Understanding how India's map reached its current form helps in answering questions about "newest state" or "when was X state formed." At Independence in 1947, Indian states were a patchwork of British provinces and princely states integrated through the efforts of Sardar Vallabhbhai Patel. The States Reorganisation Act of 1956 redrew internal boundaries largely on linguistic lines, following the recommendations of the States Reorganisation Commission (Fazal Ali Commission), and is the single most important law in this history.
| Year | Development |
|---|---|
| 1953 | Andhra State created — the first state formed purely on a linguistic basis, carved from Madras State |
| 1956 | States Reorganisation Act reorganises states largely along linguistic lines |
| 1960 | Bombay State split into Maharashtra and Gujarat |
| 1963 | Nagaland becomes a full state, the first in the Northeast formed on ethnic lines |
| 1966 | Punjab reorganised; Haryana and the Union Territory of Chandigarh created |
| 1971-72 | Meghalaya, Manipur, and Tripura attain full statehood |
| 1975 | Sikkim becomes the 22nd state of India after a referendum, ending its status as a protectorate |
| 1987 | Arunachal Pradesh, Mizoram, and Goa become full states |
| 2000 | Chhattisgarh (from Madhya Pradesh), Uttarakhand (from Uttar Pradesh), and Jharkhand (from Bihar) are created |
| 2014 | Telangana is carved out of Andhra Pradesh, becoming the 29th state at the time |
| 2019 | Jammu and Kashmir reorganised into two Union Territories — Jammu and Kashmir (with legislature) and Ladakh (without legislature), effective 31 October 2019, reducing the state count to 28 |
Lakes of India
Lakes are a smaller but recurring topic, often clubbed with rivers in the same question set.
| Lake | State | Type/Notes |
|---|---|---|
| Wular Lake | Jammu and Kashmir | Largest freshwater lake in India |
| Dal Lake | Jammu and Kashmir | Famous for houseboats in Srinagar |
| Chilika Lake | Odisha | Largest brackish-water lagoon in India, and in Asia |
| Vembanad Lake | Kerala | Longest lake in India, part of the backwaters |
| Sambhar Lake | Rajasthan | Largest inland saltwater lake in India |
| Loktak Lake | Manipur | Largest freshwater lake in Northeast India, known for floating islands called phumdis |
| Pulicat Lake | Andhra Pradesh/Tamil Nadu border | Second largest brackish-water lagoon in India |
| Pangong Tso | Ladakh | High-altitude endorheic lake straddling the India-China border |
Interstate River Water Disputes
River water sharing has been a persistent source of interstate friction, and tribunal names are commonly tested.
| Dispute | States Involved | Tribunal |
|---|---|---|
| Cauvery Water Dispute | Karnataka, Tamil Nadu, Kerala, Puducherry | Cauvery Water Disputes Tribunal; final order given effect by Supreme Court in 2018 |
| Krishna Water Dispute | Maharashtra, Karnataka, Andhra Pradesh, Telangana | Krishna Water Disputes Tribunal |
| Godavari Water Dispute | Maharashtra, Karnataka, Andhra Pradesh, Telangana, Odisha, Madhya Pradesh | Godavari Water Disputes Tribunal |
| Narmada Water Dispute | Madhya Pradesh, Gujarat, Maharashtra, Rajasthan | Narmada Water Disputes Tribunal |
| Ravi-Beas Water Dispute | Punjab, Haryana, Rajasthan | Ravi and Beas Waters Tribunal |

| Godavari | ~1,465 | Peninsular; longest Peninsular river |
| Krishna | ~1,400 | Peninsular |
| Yamuna | ~1,376 | Himalayan; largest tributary of the Ganga |
| Narmada | ~1,312 | Peninsular; west-flowing |
| Indus (in India) | ~1,114 | Himalayan; most of its course lies in Pakistan |

Canals and Irrigation Projects Linked to Rivers
A few canal systems are frequently tested alongside dam questions. The Indira Gandhi Canal, the longest canal in India, originates from the Harike Barrage (formed by the Sutlej and Beas rivers) in Punjab and irrigates the arid regions of Rajasthan, notably Bikaner and Jaisalmer districts. The Upper Ganga Canal, built during the colonial period, takes off from the Ganga at Haridwar. The Buckingham Canal runs along the Coromandel Coast of Tamil Nadu and Andhra Pradesh, connecting several east-flowing rivers for inland navigation.
Mountain Passes and Peaks Related to State Geography
A note before this section: passes are a small but reliable source of one-mark questions, so treat the list below as core memory work rather than optional reading.
A few high mountain passes are frequently asked about in relation to specific states: the Nathu La and Jelep La passes connect Sikkim to Tibet; the Rohtang Pass lies in Himachal Pradesh on the route to Lahaul-Spiti; the Zoji La pass connects Srinagar to Leh in the Union Territory of Ladakh; and the Bomdi La pass is in Arunachal Pradesh. Kanchenjunga, the third highest peak in the world, straddles the border of Sikkim and Nepal and is the highest peak located within India.
Major Waterfalls of India
Waterfalls are often paired with river or state questions in the same exam.
| Waterfall | State | River |
|---|---|---|
| Jog Falls | Karnataka | Sharavathi — one of the highest waterfalls in India |
| Chitrakote Falls | Chhattisgarh | Indravati — known as the "Niagara of India" for its width |
| Dudhsagar Falls | Goa | Mandovi |
| Athirappilly Falls | Kerala | Chalakudy |
| Nohkalikai Falls | Meghalaya | Local stream near Cherrapunji — tallest plunge waterfall in India |
| Hogenakkal Falls | Tamil Nadu | Kaveri |
Districts, Neighbours and Boundary Facts
Madhya Pradesh borders the largest number of other states, sharing boundaries with Uttar Pradesh, Chhattisgarh, Maharashtra, Gujarat, Rajasthan, and (a small stretch) with other neighbouring states, which is why it is sometimes called the "heart of India," both geographically and in terms of connectivity. Uttar Pradesh similarly borders a large number of states, including Uttarakhand, Himachal Pradesh (a brief touch), Haryana, Delhi, Rajasthan, Madhya Pradesh, Chhattisgarh, Jharkhand, and Bihar.
Among Union Territories, only three have their own elected Legislative Assembly and Council of Ministers — Delhi, Puducherry, and Jammu and Kashmir — while the remaining five are governed directly by administrators appointed by the President, usually styled Lieutenant Governor or Administrator depending on the territory.
