Rivers and Lakes of India

Vembanad and Ashtamudi are major lakes of Kerala's backwater region. For exams remember coastal lakes of Kerala.

The direct answer is D, Kerala. Sasthamkotta Lake is a freshwater lake in Kerala, in southern India. A freshwater lake contains water with very little dissolved salt, unlike a sea or a salt lake. The reasoning is: identify the lake, recall its state, and match that state with the option. Option A, Rajasthan, is wrong because Sasthamkotta is not a Rajasthani lake; Rajasthan is known for places such as Sambhar, a saline lake. Option B, Sikkim, is wrong because Sikkim has Himalayan lakes, but Sasthamkotta is in Kerala. Option C, Manipur, is wrong because Loktak Lake is the famous lake associated with Manipur. Option D, Kerala, is correct because Sasthamkotta is Kerala’s well-known freshwater lake. Do not confuse it with Vembanad, which is also in Kerala but is a different and much larger lake. Memory cue: “Sasthamkotta—Kerala’s freshwater lake.”

Lonar Lake in Maharashtra is famous as a meteoritic crater lake. For exams remember its origin.

Pangong Tso and Tso Moriri are high altitude lakes of Ladakh. For exams place them among Himalayan lakes.

Gurudongmar and Tsomgo are high altitude lakes of Sikkim. For exams identify Sikkim lakes on the map.

Chandratal and Suraj Tal are high altitude lakes of Himachal Pradesh. For exams link them with the Lahaul Spiti region.

Umiam Lake is located near the Shillong region in Meghalaya. For exams remember northeastern lakes with states.

Rudrasagar Lake is in Tripura and is linked with Neermahal. For exams study lakes of Northeast India separately.

Bhojtal is a famous lake of Bhopal and was also called Upper Lake. For exams remember Bhopal and Bhojtal together.

The direct answer is C, Hyderabad and Telangana. Hussain Sagar is an urban lake associated with Hyderabad, which is in Telangana. To solve it, match the lake with its city first and then with the state: Hussain Sagar → Hyderabad → Telangana. Option A, Bhopal and Madhya Pradesh, is wrong because Bhopal is known for its Upper and Lower Lakes, not Hussain Sagar. Option B, Udaipur and Rajasthan, is wrong because Udaipur has lakes such as Pichola and Fateh Sagar. Option C, Hyderabad and Telangana, is correct; Hussain Sagar lies between the Hyderabad and Secunderabad urban areas and is a major landmark. Option D, Srinagar and Jammu and Kashmir, is wrong because Srinagar is associated with Dal Lake and other Himalayan lakes. The important exam skill is city–lake matching, not merely recognising that all four places have lakes. Memory cue: “Hussain Sagar—Hyderabad.”

Govind Sagar is a reservoir formed by Bhakra Nangal Dam. For exams remember Sutlej Bhakra and Govind Sagar together.

Jayakwadi Dam is located on the Godavari River in Maharashtra. For exams remember river projects of Maharashtra.

Almatti Dam is located on the Krishna River in Karnataka. For exams study projects of the Krishna system separately.

Gandhi Sagar and Rana Pratap Sagar are linked with the Chambal River project. For exams remember Chambal Valley projects.

Ukai Dam is constructed on the Tapi River in Gujarat. Tapi is one of India’s important west-flowing rivers and drains into the Gulf of Khambhat in the Arabian Sea. Kaveri, Ganga, and Brahmani flow eastward towards the Bay of Bengal, so they are incorrect. Exam tip: remember Ukai Dam with Tapi River and Gujarat.

Pong Dam is on the Beas River and Beas is linked with the Indus system. For exams remember dam river matching of the Indus system.

Mullaperiyar and Idukki are projects linked with the Periyar river area. For exams remember Kerala and Periyar relation.

Jog Falls is located on the Sharavathi River in Karnataka. For exams remember waterfall river state matching.

Studying state river system mouth and feature together makes map questions easier. For exams connect every river and lake with the map.

Ken River is a tributary of the Yamuna river system. For exams link Ken and Betwa with the Bundelkhand region.

Betwa River is a tributary of Yamuna. For exams link Betwa with central India and the Bundelkhand region.

The direct answer is C: the Chambal system. The Banas is an important river of Rajasthan. It joins the Chambal River, so it is treated as a tributary within the Chambal river system. The reasoning is: identify the Banas as a Rajasthan river, then identify its drainage connection with the Chambal; therefore option C follows. Option A is wrong because the Kaveri system is mainly associated with southern India and the Banas does not belong to it. Option B is wrong because the Banas is not generally classified as a tributary of the Ganga system in this question. Option D is wrong because the Tapi is a separate west-flowing river system. Memory cue: Rajasthan's Banas joins the Chambal system.

Kali Sindh River is a tributary of the Chambal system. For exams study Chambal tributaries as a group.

A tributary is a smaller stream or river that flows into a larger river. The Rihand River is an important tributary of the Son River in the Ganga drainage system. The Rihand Dam and reservoir are associated with this river, making the Rihand–Son relationship useful in Indian geography. The question asks which major river receives the Rihand’s water.

The correct choice is A, Son. Tapi, Kaveri, and Sutlej belong to different river systems and do not receive the Rihand as a tributary. A helpful study link is “Rihand joins Son.” Once this drainage relationship is known, the other choices can be rejected because they are not part of the immediate river system of the Rihand.

Rihand Dam is associated with the Son river system area of Uttar Pradesh. For exams study dam river and state matching together.
