Which one of the following places is not located on the bank of river Ganga ?

1. Introduction to Indian Drainage Systems (basic)

Welcome to your first step in mastering Indian Geography! To understand India's landscape, we must first look at its Drainage System — which is simply the river system of an area. In India, the flow of water is dictated by the massive relief features of our subcontinent. Because India has such diverse terrain, our rivers are broadly categorized into two major groups: the Himalayan Rivers and the Peninsular Rivers. CONTEMPORARY INDIA-I, Chapter 3: Drainage, p.17

The fundamental difference lies in their water source and geological age. Himalayan rivers are perennial, meaning they flow year-round because they are fed by both melting glaciers (snow-melt) and monsoon rains. In contrast, Peninsular rivers are mostly seasonal; their flow is strictly dependent on rainfall, often shrinking significantly during the dry season. Geography of India, The Drainage System of India, p.22

One fascinating concept you must know for UPSC is Antecedent Drainage. Imagine a river already flowing in its path. Suddenly, the land beneath it begins to rise (like the Himalayas lifting up). Instead of changing course, the river acts like a saw, cutting through the rising land at the same rate it lifts, forming deep, vertical gorges. Rivers like the Indus, Sutlej, and Brahmaputra are actually older than the Himalayas themselves! Physical Geography by PMF IAS, Fluvial Landforms and Cycle of Erosion, p.211

To help you distinguish between the two systems at a glance, look at this comparison:

Feature	Himalayan Rivers	Peninsular Rivers
Nature of Flow	Perennial (Year-round)	Seasonal (Monsoon-dependent)
Drainage Type	Often Antecedent (Older than mountains)	Superimposed/Consequent (Follows the slope)
Valleys	Deep V-shaped valleys and Gorges	Broad, shallow, and mature valleys
Examples	Indus, Ganga, Brahmaputra	Mahanadi, Godavari, Krishna, Kaveri

2. The Course of the Ganga River (basic)

The Ganga River, the most sacred and important river of India, begins its journey high in the Himalayas. It is officially formed at Devprayag by the confluence of two major headstreams: the Bhagirathi (which rises from the Gangotri Glacier at Gaumukh) and the Alaknanda (which rises from the Satopanth Glacier). It is important to note that while the town of Uttarkashi is often associated with the river's origin, it actually sits on the banks of the Bhagirathi. The river only takes the name 'Ganga' after the two streams unite at Devprayag Geography of India, Majid Husain, The Drainage System of India, p.11.

After descending from the mountains, the Ganga enters the Great Northern Plains at Haridwar. From here, it flows through a massive basin covering about 861,400 sq km, traversing the states of Uttarakhand, Uttar Pradesh, Bihar, and West Bengal Geography of India, Majid Husain, Climate of India, p.47. Geographically, the course is divided into three distinct sections:

Region	Characteristics	Key Locations
Upper Ganga Plain	Includes the Ganga-Yamuna Doab and Rohilkhand; elevation varies from 100m to 300m.	Haridwar, Kanpur, Fatehpur
Middle Ganga Plain	A low gradient plain where rivers often shift courses; home to major tributaries like Gandak and Kosi.	Varanasi, Patna, Bhagalpur
Lower Ganga Plain	Transition into the deltaic region before merging with the Brahmaputra.	Murshidabad, Kolkata (on Hooghly)

As the Ganga flows eastward, it reaches the Rajmahal Hills in Jharkhand and then enters West Bengal. Near Farakka, the river bifurcates: the Hooghly-Bhagirathi (distributary) flows through West Bengal into the Bay of Bengal, while the main stream enters Bangladesh, where it is known as the Padma. Eventually, it joins the Jamuna (Brahmaputra) and the Meghna to form the world's largest delta, the Sunderbans, before emptying into the sea Geography of India, Majid Husain, The Drainage System of India, p.11.

3. The Panch Prayag: Sacred Confluences (intermediate)

To understand the birth of the Ganga, we must travel to the high Himalayas of Uttarakhand, where a series of sacred confluences known as the Panch Prayag (Five Confluences) take place. Think of the river Alaknanda as the central spine of this system. It originates from the Satopanth Glacier above Badrinath and flows downstream, receiving various tributaries at specific points until it finally transforms into the Ganga. INDIA PHYSICAL ENVIRONMENT, Geography Class XI (NCERT 2025 ed.), Drainage System, p.21

The journey begins at Vishnu Prayag, where the Alaknanda meets the Dhauli Ganga near Joshimath. As the river descends, it reaches Nand Prayag to meet the Nandakini, followed by Karna Prayag, where it is joined by the Pindar river. The penultimate confluence is Rudra Prayag, where the Mandakini (also called Kali Ganga), which originates from the Chorabari Glacier near Kedarnath, merges with the Alaknanda. Geography of India, Majid Husain (McGrawHill 9th ed.), The Drainage System of India, p.11

The most significant of these is Devprayag. Here, the Alaknanda meets the Bhagirathi. The Bhagirathi is often considered the primary source stream of the Ganga, rising from the Gangotri Glacier at Gaumukh in the Uttarkashi district. Geography of India, Majid Husain (McGrawHill 9th ed.), The Drainage System of India, p.11 It is only after this meeting at Devprayag that the combined river is officially named the Ganga. From here, the river cuts through the Lesser Himalayas before finally debouching (emerging) into the North Indian plains at Haridwar. INDIA PHYSICAL ENVIRONMENT, Geography Class XI (NCERT 2025 ed.), Drainage System, p.21

Confluence (Prayag)	Main River	Tributary River
Vishnu Prayag	Alaknanda	Dhauli Ganga
Nand Prayag	Alaknanda	Nandakini
Karna Prayag	Alaknanda	Pindar
Rudra Prayag	Alaknanda	Mandakini (Kali Ganga)
Devprayag	Alaknanda	Bhagirathi

4. Major Tributaries: Left and Right Bank (intermediate)

To master the drainage system of India, we first need a simple rule of thumb: to distinguish between a Left Bank and a Right Bank tributary, imagine you are standing in the river, facing downstream (the direction the water is flowing). Everything to your left is a left-bank tributary, and everything to your right is a right-bank tributary. For the Ganga, which flows generally East and Southeast, its northern Himalayan tributaries are mostly 'Left Bank,' while its southern Peninsular tributaries are 'Right Bank.'

The Ganga receives its most significant volume from the Himalayan rivers to its north. These Left Bank Tributaries include the Ramganga, Gomati, Ghaghara, Gandak, Kosi, and Mahananda INDIA PHYSICAL ENVIRONMENT, Geography Class XI (NCERT 2025 ed.), Drainage System, p.22. Rivers like the Ghaghara, Gandak, and Kosi originate in the Nepal Himalayas and are notorious for shifting their courses and causing annual floods, though they also provide the fertile silt that makes the Northern Plains the 'breadbasket' of India CONTEMPORARY INDIA-I, Geography, Class IX (Revised ed 2025), Drainage, p.20.

On the Right Bank, the Ganga is joined by two major rivers: the Yamuna and the Son Geography of India, Majid Husain, Physiography, p.40. The Yamuna is the western-most and longest tributary, joining the Ganga at Prayag (Allahabad). Interestingly, the Yamuna has its own set of tributaries—the Chambal, Sind, Betwa, and Ken—which are considered right-bank tributaries of the Yamuna itself, originating from the Peninsular block (Vindhyan and Malwa regions) Geography of India, Majid Husain, The Drainage System of India, p.13.

Feature	Left Bank Tributaries (Ganga)	Right Bank Tributaries (Ganga)
Source Region	Himalayas / Nepal Himalayas	Peninsular Uplands / Yamunotri Glacier
Major Rivers	Ramganga, Gomati, Ghaghara, Gandak, Kosi, Mahananda	Yamuna, Son
Characteristics	Perennial, flood-prone, high sediment load	Combination of perennial (Yamuna) and non-perennial (Son)

5. Economic and Cultural Geography: National Waterway 1 (intermediate)

To understand India's connectivity, we must look beyond roads and rails to our 'Blue Highways.' **National Waterway 1 (NW1)** is the crown jewel of India's inland water transport system. Established under the authority of the **Inland Waterways Authority of India (IWAI)**—which was set up in 1986 to regulate and develop these routes—NW1 spans a massive **1,620 km** INDIA PEOPLE AND ECONOMY (NCERT 2025 ed.), Transport and Communication, p.81. It is not just a single river channel; technically, it traverses the **Ganga-Bhagirathi-Hooghly river system**, connecting the industrial heartland of North India to the maritime gates of West Bengal Indian Economy, Nitin Singhania (2nd ed.), Infrastructure, p.459. Historically and economically, NW1 serves as a vital artery passing through four major states: **Uttar Pradesh, Bihar, Jharkhand, and West Bengal**. While the entire stretch is iconic, its navigability varies with the river's depth and flow. For instance, while ordinary boats can reach as far upstream as **Haridwar**, the heavy-duty mechanical barges essential for modern commerce generally navigate up to **Patna** INDIA PEOPLE AND ECONOMY (NCERT 2025 ed.), Transport and Communication, p.81. To boost this capacity, the government has implemented the *Jal Marg Vikas Project*, which involves constructing massive multi-modal terminals at key hubs like **Varanasi, Sahibganj, and Haldia**. Beyond just moving cargo, NW1 is being reimagined as a 'cultural and industrial corridor.' A fascinating development here is the creation of India’s first **'freight village' in Varanasi**. This 100-acre specialized industrial estate is designed to act as a logistics hub, allowing for the seamless transfer of goods between ships, trucks, and trains Geography of India, Majid Husain (9th ed.), Transport, Communications and Trade, p.23. However, this development is balanced with ecological sensitivities. Initiatives like **'Aviral Dhara'** (ensuring continuous flow) and **'Nirmal Dhara'** (ensuring unpolluted flow) are central to the National Mission for Clean Ganga, ensuring that shipping and tourism do not compromise the river’s sacred and biological health Environment, Shankar IAS Academy (10th ed.), Aquatic Ecosystem, p.60.

6. Specific Geography of Uttarakhand Rivers (exam-level)

To understand the geography of North India, we must first look at the Upper Himalayan drainage, where the river Ganga is not born as a single stream, but as a series of sacred confluences. The river officially takes the name 'Ganga' only at Devprayag, where two major headstreams meet: the Bhagirathi and the Alaknanda INDIA PHYSICAL ENVIRONMENT, Geography Class XI, Drainage System, p.25.

The Bhagirathi is considered the source stream. It rises from the Gangotri glacier at Gaumukh, located in the Uttarkashi district of Uttarakhand. Because the town of Uttarkashi is situated far upstream from Devprayag, it technically sits on the banks of the Bhagirathi, not the Ganga proper INDIA PHYSICAL ENVIRONMENT, Geography Class XI, Drainage System, p.21. Conversely, the Alaknanda originates from the Satopanth glacier above Badrinath and acts as a 'collector' river, gathering several tributaries through a system known as the Panch Prayag (Five Confluences) before it reaches the Bhagirathi Geography of India by Majid Husain, The Drainage System of India, p.11.

The journey of the Alaknanda is a masterclass in Himalayan geography. It begins with the meeting of the Dhauli Ganga and Vishnu Ganga at Vishnu Prayag. As it flows south, it encounters other major tributaries at specific points, which are vital for any UPSC aspirant to memorize:

Confluence (Prayag)	Rivers Meeting Alaknanda
Vishnu Prayag	Dhauli Ganga & Vishnu Ganga
Karna Prayag	Pindar River
Rudra Prayag	Mandakini (also called Kali Ganga)
Devprayag	Bhagirathi (Naming of Ganga)

Once the river passes Devprayag and emerges from the mountains at Rishikesh and Haridwar, it enters the Great Plains. It is only in these plains that the 'main stem' of the Ganga supports massive urban and industrial centers like Kanpur, Allahabad (Prayagraj), and Bhagalpur Geography Class IX NCERT, Chapter 3: Drainage, p. 18.

7. Solving the Original PYQ (exam-level)

This question masterfully tests your ability to synthesize the building blocks of the Indian Drainage System that you have just studied. In the NCERT Class IX Geography: Drainage, we learn that the river Ganga does not begin its journey under that name. Instead, it is formed by the confluence of two distinct headstreams—the Bhagirathi and the Alaknanda—which meet at Devprayag. This conceptual distinction between a 'headstream' and the 'main stem' is the critical filter you must apply to solve this PYQ.

To reach the correct answer, (A) Uttarkashi, you must visualize the river's path through the upper Himalayas. While Uttarkashi is a major town in the district where the Ganga’s source (the Gangotri Glacier) is located, it actually sits on the banks of the Bhagirathi. Because the name 'Ganga' is only officially applied after the confluence at Devprayag, Uttarkashi is technically located on a headstream rather than the Ganga itself. This requires a level of precision where you distinguish between the spiritual/administrative region of the river and its geographical nomenclature.

The other options—Kanpur, Fatehpur, and Bhagalpur—are classic UPSC distractors representing the Middle Ganga Plain. Kanpur and Fatehpur are industrial and administrative hubs in Uttar Pradesh, while Bhagalpur is a key riverine city in Bihar; all three sit directly on the main stem of the Ganga after it has descended from the mountains. The 'trap' here lies in the student's familiarity: because Uttarkashi is so closely associated with the Ganga's origin in public consciousness, one might assume it must be on the river's bank. UPSC rewards the student who remembers that location and nomenclature are not always synonymous.
