Rivers and Lakes of India

Vembanad Lake is one of the most famous lakes of Kerala. It is important in Kerala's backwater system.

Sambhar Lake is a famous saltwater lake in Rajasthan. It is important for exams because of salt production.

Hirakud Dam is built across the Mahanadi River in Odisha. It is a major multipurpose river-valley project used for flood control, irrigation, and hydropower generation. The Kaveri has dams such as Krishnarajasagara, so it is not the correct option here. Exam tip: learn important dams together with their rivers and states.

The Sardar Sarovar Dam is a major multipurpose project built across the Narmada River. The Narmada flows westward across central India and has a long valley that has supported several development and irrigation projects. The dam is connected with the Narmada Valley Project, which includes purposes such as irrigation, water supply and hydroelectric power. Identifying the river is therefore an important part of Indian geography.

Option A, Narmada, is correct. Sutlej, Damodar and Jhelum are different rivers associated with other regions and projects. The safest memory link is “Sardar Sarovar–Narmada,” just as the name Narmada Valley Project reinforces the association. The question asks for the river on which the dam stands, not the state or the project’s purpose, so Narmada directly answers it.

Bhakra Nangal Dam is built on the Sutlej river. It is a major multipurpose project of North India.

Damodar was called the Sorrow of Bengal because of floods. Dams and projects later helped control it.

The Kosi is called the Sorrow of Bihar because it often changes course and causes floods. River nicknames are useful for exams.

Punjab means the land of five rivers. Jhelum Chenab Ravi Beas and Sutlej are linked with this region.

Beas is an important tributary of the Indus river system. Remember Himalayan river systems separately.

The confluence of Ganga and Yamuna is at Prayagraj. Confluence places are important in map based questions.

The Son is a southern tributary of the Ganga. Learn tributaries by linking them with their main rivers.

Ghaghara is a major tributary of the Ganga. Tributaries of Ganga are important in North Indian geography.

The Chambal is an important river of north-central India and a major tributary of the Yamuna. It flows through the Malwa region and parts of Madhya Pradesh, Rajasthan and Uttar Pradesh before joining the Yamuna in Uttar Pradesh. Through the Yamuna, its waters ultimately become part of the Ganga river system. Hence option A is correct. The Godavari belongs to the peninsular river system of south-central India, while the Brahmaputra follows a different Himalayan and northeastern course. The Mahanadi drains toward the Bay of Bengal through eastern India. The association of Chambal with ravines and the Yamuna basin is a useful geographical clue, but the decisive relationship in this question is its confluence with the Yamuna.

The Betwa is a tributary of the Yamuna. Remember it in the context of Madhya Pradesh and Uttar Pradesh.

The Luni is a major river of the dry region of Rajasthan. Desert rivers may not always reach the sea.

The Sabarmati is mainly associated with Gujarat, and Ahmedabad lies on its banks. Although the river rises in the Aravalli Hills of Rajasthan, its major course and its mouth in the Arabian Sea are in Gujarat. Therefore, Rajasthan is the source state, but Gujarat is the correct answer here. Exam tip: Distinguish between a river’s source state and the state with which it is chiefly associated.

The Jhelum is mainly associated with the Kashmir Valley. It is an important river of the Indus system.

The Ganga drains into the Bay of Bengal. Remember the final drainage of major east flowing rivers.

The Sundarbans delta is linked with the Ganga Brahmaputra river system. It is counted among the world's largest delta regions.

The Krishna flows eastward into the Bay of Bengal. Most peninsular rivers are east flowing.
