Rivers and Lakes of India

Dal Lake is a famous lake of Srinagar and is known for shikara boats. For exams remember Dal Lake and Srinagar together.

The direct answer is C, Chandigarh. Sukhna Lake is a famous urban lake associated with Chandigarh, a carefully planned city near the Shivalik foothills. It was developed as an important public and recreational feature of the city. Option A, Jaipur, is incorrect because Jaipur is in Rajasthan and is not associated with Sukhna Lake. Option B, Kochi, is a coastal city in Kerala and has different water bodies; it is not the location of Sukhna Lake. Option C is correct because Sukhna Lake belongs to the Chandigarh urban landscape. Option D, Lucknow, is in Uttar Pradesh and is not connected with this lake. The reasoning is: identify the lake → recall its city → Sukhna Lake means Chandigarh. The word “planned” is an additional clue because Chandigarh is widely known as a planned city. Memory cue: Sukhna Lake is Chandigarh’s well-known planned-city lake.

Nalsarovar Lake is a well-known shallow freshwater wetland in Gujarat and is noted for migratory birds. Hence, Gujarat is the correct answer. Chilika Lake is the famous wetland in Odisha, not Nalsarovar. Exam tip: Remember Nalsarovar with Gujarat, wetlands, and bird sanctuary.

Deepor Beel is a wetland lake associated with the Guwahati region in Assam. For exams remember it among lakes of Assam.

Umiam Lake is located near the Shillong region in Meghalaya. For exams remember Umiam and Meghalaya together.

Rudrasagar Lake is located in Tripura and is associated with Neermahal. For exams remember it among northeastern lakes.

Ashtamudi Lake is an important lake of Kerala's backwater region. For exams remember Kerala's backwater lakes.

The direct answer is C: Nagarjuna Sagar reservoir is on the Krishna River. A reservoir is a large artificial storage of water formed when a dam holds back river flow. The Nagarjuna Sagar project was built across the Krishna, an important peninsular river. Its stored water supports irrigation, hydroelectric power generation and other uses. To solve the question, remember the project–river association: Nagarjuna Sagar–Krishna. Option C is correct. Option A, Narmada, is wrong because major projects such as Sardar Sarovar are associated with the Narmada, not Nagarjuna Sagar. Option B, Ganga, is wrong because Nagarjuna Sagar is not on the Ganga basin river channel. Option D, Sabarmati, is wrong because the Sabarmati is a different river of western India and does not carry this reservoir. The name of a project must be matched with its actual river, not merely with any large Indian river. Memory cue: Krishna’s important project pair includes Nagarjuna Sagar.

Narmada drains into the Gulf of Khambhat. For exams link Narmada with west flow and rift valley.

Tapi meets the Arabian Sea in the Gulf of Khambhat region. For exams remember Narmada and Tapi together.

Godavari and Krishna deltas are located in the coastal region of Andhra Pradesh. For exams remember the eastern coast and delta relation.

The Mahanadi delta is found in the coastal region of Odisha. For exams remember Mahanadi and the Cuttack region.

The Kaveri delta is linked with the fertile agricultural region of Tamil Nadu. For exams remember the relation between delta and agriculture.

Wetlands are important for both water and biodiversity. For exams remember examples like Nalsarovar Deepor Beel and Haiderpur.

Tungabhadra is a major tributary of the Krishna River. For exams link Tungabhadra with the river system of South India.

Pranhita is a major tributary of the Godavari. For exams remember tributaries of the Godavari system separately.

A tributary is a smaller river that joins a larger river. The Tawa is an important river of central India and joins the Narmada, so it belongs to the Narmada river system. This relationship is also useful when studying the Tawa Dam and the geography of Madhya Pradesh. The question asks for the major river receiving the Tawa’s flow.

The correct choice is A, Narmada. The Ganga, Krishna, and Kaveri are major river systems, but Tawa is not their tributary. A useful memory link is “Tawa–Narmada”: the Tawa contributes its water to the Narmada before the larger river continues its course toward the Arabian Sea. Thus the drainage-system match clearly supports option A.

Pong Dam is built across the Beas River in Himachal Pradesh. Its reservoir is also known as Maharana Pratap Sagar. Sutlej is a nearby but incorrect distractor because the Bhakra Dam is associated with the Sutlej River. Exam tip: Remember key Himachal Pradesh dam-river pairs: Pong–Beas and Bhakra–Sutlej.

Koyna project is an important hydroelectric project of Maharashtra. For exams also link Koyna with the Krishna river system.

Keibul Lamjao National Park is linked with the phumdi area of Loktak Lake. For exams remember Loktak Manipur and phumdi.

Teesta is an important river linked with the Brahmaputra system. For exams link Teesta with Sikkim and North Bengal.

The direct answer is C: Northeast India. The Barak River is an important river of the northeastern part of India, especially associated with the Barak Valley in Assam. From its course in the northeast, the river system continues towards Bangladesh. C is correct because the Barak Valley and much of the Indian Barak basin are in Assam and the wider Northeast. A is wrong because western Rajasthan is an arid region far from the Barak River. B is wrong because the Malabar Coast is on the southwestern coast and is associated with different short coastal rivers. D is wrong because the Kachchh region is in western Gujarat and is not the Barak basin. The key geographical clue is Barak Valley–Assam–Northeast India. Memory cue: Barak belongs to the Northeast, especially Assam.

The direct answer is A: Krishna system. The Musi is a tributary of the Krishna River, and it flows through Hyderabad, Telangana, before joining the Krishna system. Reason step by step: first identify the river; then remember its regional location in Telangana; finally connect it with the Krishna basin. Option A is correct because Musi belongs to the Krishna drainage system. Option B, the Ganga system, is wrong because the Musi is not a tributary of the Ganga. Option C, the Indus system, is wrong because the Indus basin is mainly in the north-west, whereas Musi is a peninsular river. Option D, the Narmada system, is wrong because Musi does not drain into the Narmada. Memory cue: Musi—Hyderabad—Krishna.

Pushkar Lake is a famous religious lake in the Ajmer region of Rajasthan. For exams remember Pushkar and Ajmer together.

Periyar is a major river of Kerala and is important for the state's water resources. For exams remember the Periyar and Idukki relation.
