Rivers and Lakes of India

Pennar is an east flowing Peninsular river and drains into the Bay of Bengal. For exams remember it as a river between Krishna and Kaveri.

Mettur Dam is located on the Kaveri River in Tamil Nadu. For exams remember the irrigation importance of Kaveri.

Tehri Dam is on Bhagirathi and Bhagirathi is an upper course stream of the Ganga system. For exams remember Bhagirathi Alaknanda and Devprayag.

Ukai Dam is linked with the Tapi River in the Gujarat region. For exams remember Tapi dams and Gulf of Khambhat relation.

Nagarjuna Sagar is a major project linked with the Krishna river system. For exams study projects of the Krishna system separately.

Almatti Dam is located on the Krishna River in Karnataka. For exams remember major projects of the Krishna River.

Dudhsagar Falls is linked with the Mandovi river area and Western Ghats of Goa. For exams remember waterfall river and state matching.

Shivanasamudra Falls is associated with the Kaveri River. For exams remember waterfalls and dams of Kaveri separately.

Sasthamkotta is a famous freshwater lake of Kerala. For exams distinguish it from Vembanad backwater.

High discharge and silt deposition in the Brahmaputra cause channel shifting and river islands. For exams link Brahmaputra with Assam and Majuli.

The correct answer is Sutlej. The Sutlej rises in the Tibetan Plateau near the Rakshastal–Mansarovar region and then flows toward India, entering Himachal Pradesh near Shipki La. In the Himalayas it cuts a remarkably deep gorge before continuing through the state and later joining the Indus river system. Jhelum is associated with the Kashmir Valley and rises near Verinag, while Chenab is formed by the confluence of the Chandra and Bhaga rivers. Ravi rises near the Bara Bhangal region of Himachal Pradesh. Thus, the combination of a Tibetan source near Rakshastal and a deep gorge in Himachal Pradesh identifies Sutlej.

The correct answer is Narmada. It rises at or near Amarkantak in Madhya Pradesh and travels westward through a structural rift valley between the Vindhya and Satpura ranges. It eventually enters the Arabian Sea through the Gulf of Khambhat. This westward direction is an important geographical distinction because most major peninsular rivers, such as the Mahanadi, Godavari, Krishna, and Kaveri, flow eastward into the Bay of Bengal. Tapi is also a west-flowing river and reaches the Arabian Sea, but its source is in the Satpura region near Multai, not Amarkantak. Son rises near Amarkantak but flows generally eastward as a tributary of the Ganga.

The correct answer is Godavari, popularly called the Dakshin Ganga or Ganga of the South. It is the longest river of peninsular India and has one of the largest drainage basins among Indian rivers. It rises near Trimbakeshwar in Maharashtra and flows generally eastward across the Deccan Plateau before reaching the Bay of Bengal through a broad delta. Krishna is another major east-flowing peninsular river, but it is shorter and is not normally identified by the title Dakshin Ganga. Kaveri has great cultural and agricultural importance but a smaller basin. Pennar is also an east-flowing river, yet its basin is considerably smaller. The large basin and southern comparison with the Ganga point specifically to Godavari.

The correct answer is Loktak Lake in Manipur. It is famous for phumdis, which are floating masses made from a mixture of vegetation, soil, and organic matter. These formations are a distinctive ecological feature of the lake and support a variety of plants and animals. The Keibul Lamjao National Park, often described as the world’s only floating national park, is located on phumdis in the southern part of Loktak Lake and provides habitat for the endangered sangai deer. Dal Lake is in Kashmir and is known for houseboats and gardens. Vembanad is a large backwater lake in Kerala, while Kolleru is a freshwater lake in Andhra Pradesh. Their locations and features do not match the question.

The correct answer is Dihang, also called Siang in parts of Arunachal Pradesh. In Tibet, the river is known as the Yarlung Tsangpo or Tsangpo. After cutting across the Himalayas and entering Arunachal Pradesh, it is commonly called Dihang or Siang. Farther downstream, the Dihang joins the Lohit and Dibang rivers near the eastern part of Assam; after this major confluence, the combined river is known as the Brahmaputra in Assam. Lohit is therefore a tributary rather than the name of the entire post-entry course. Kali is a separate Himalayan river associated with the Kali or Mahakali system, and Bhagirathi is a headstream of the Ganga. The sequence of changing names makes Dihang the appropriate answer.

The correct answer is Sambhar Lake. Located in Rajasthan, Sambhar is India’s largest inland salt lake and occupies a broad shallow depression that collects water from seasonal streams. High evaporation in the arid climate leaves dissolved salts behind, making salt extraction an important local economic activity. Pushkar Lake near Ajmer is a small freshwater lake with religious significance. Nakki Lake is a small highland lake at Mount Abu and is also freshwater. Jaisamand, or Dhebar Lake, is a large artificial freshwater reservoir created by a dam in Rajasthan. These distinctions matter because the question combines three clues: Rajasthan, inland location, and saline water. Taken together, those clues identify Sambhar and exclude the other listed lakes.

The correct answer is Yamuna. Chambal rises in the northern part of the Vindhya region and flows through or along Madhya Pradesh, Rajasthan, and Uttar Pradesh before joining the Yamuna near the Pachnada area. It is one of the important tributaries of the Yamuna and is also known for the Chambal ravines and the river’s relatively clean habitat supporting the gharial and the Ganges river dolphin in parts of its course. Betwa, Ken, and Sind are other significant tributaries associated with the Yamuna system. Narmada and Godavari are separate major peninsular rivers, while the Ganga is the larger river into which the Yamuna ultimately flows, not the immediate main river receiving the Chambal. Therefore, the direct tributary relationship is Chambal–Yamuna.

The correct answer is the Brahmagiri Hills. The Kaveri rises at Talakaveri, a revered source area situated in the Brahmagiri range of Kodagu district in Karnataka, close to the Karnataka–Kerala border. From there it flows generally southeast and east through Karnataka and Tamil Nadu before reaching the Bay of Bengal. Mahadeo Hills are associated with the Satpura region of central India and not with the Kaveri source. The Aravalli range lies mainly in northwestern India, including Rajasthan, and is unrelated to this river’s origin. Khasi Hills are in Meghalaya in northeastern India and are associated with a different climatic and drainage setting. The place-name Talakaveri can help connect the Kaveri to the Brahmagiri Hills in map-based questions.

The correct answer is Chilika Lake. It is a large brackish-water lagoon along the Odisha coast, separated from the Bay of Bengal by a sandbar but connected with the sea through channels. Its salinity changes across the lagoon and between seasons because seawater mixes with freshwater brought by rivers and rainfall. Chilika supports rich fishery resources and is an important wintering ground for migratory birds. Wular Lake is a major freshwater lake in Jammu and Kashmir. Hussain Sagar is a man-made freshwater reservoir between Hyderabad and Secunderabad, while Naini Lake is a freshwater hill lake in Uttarakhand. The terms Odisha coast, lagoon, and brackish water together provide a precise identification of Chilika.

The correct answer is Brahmaputra. The river is known as Yarlung Tsangpo or Tsangpo in Tibet and as Dihang or Siang after entering Arunachal Pradesh. In the eastern part of Assam, Dihang joins the Lohit and Dibang rivers. After this important confluence, the combined channel is known mainly as the Brahmaputra as it flows westward through the Assam Valley. Subansiri is another major tributary of the Brahmaputra, not the name of the combined main river. Teesta is a separate Himalayan river that joins the Brahmaputra system farther downstream in Bangladesh, while Meghna is the name of a major river in Bangladesh formed within the Ganga–Brahmaputra–Meghna delta system. The sequence of regional names and confluences therefore makes Brahmaputra unambiguous.
