The Hirakud Dam is built across the Mahanadi River in the state of Odisha, India. It is one of the earliest major multipurpose river valley projects undertaken after India’s independence.
– Hirakud Dam is located in Odisha, India.
– It is constructed on the Mahanadi River.
– It is a multipurpose project serving irrigation, power generation, and flood control.
Completed in 1957, the Hirakud Dam is one of the longest earth dams in the world. The reservoir formed by the dam, also known as Hirakud Reservoir, is one of the largest artificial lakes in Asia. The dam helps regulate the flow of the Mahanadi, mitigating floods in the delta region and providing irrigation water to large areas.

Three pairs are not correctly matched.
– Pair 1 (Ghataprabha – Telangana): Incorrect. The Ghataprabha dam and reservoir are located in Karnataka, on the Ghataprabha river, a tributary of the Krishna river.
– Pair 2 (Gandhi Sagar – Madhya Pradesh): Correct. The Gandhi Sagar Dam is one of the four major dams built on the Chambal River, located in Madhya Pradesh.
– Pair 3 (Indira Sagar – Andhra Pradesh): Incorrect. The Indira Sagar Dam is a multi-purpose project built on the Narmada River in Madhya Pradesh. While there are projects named after Indira Gandhi related to irrigation in the Andhra Pradesh/Telangana region (e.g., Indirasagar Polavaram Project), the large dam typically referred to as ‘Indira Sagar’ is in MP.
– Pair 4 (Maithon – Chhattisgarh): Incorrect. The Maithon Dam is located in Jharkhand, built on the Barakar River, a tributary of the Damodar River. It is part of the Damodar Valley Corporation projects.
Thus, pairs 1, 3, and 4 are incorrectly matched.
Reservoirs and dams are crucial for irrigation, power generation, and flood control. Knowing their locations is important for understanding India’s water resources and geography. The rivers associated are: Ghataprabha (Krishna tributary), Gandhi Sagar (Chambal), Indira Sagar (Narmada), Maithon (Barakar/Damodar).

The correct answer is D) Water reservoirs.
Aliyar, Isapur, and Kangsabati are all locations in India known for significant dams and associated water reservoirs.
– Aliyar Dam is in Tamil Nadu, creating the Aliyar Reservoir.
– Isapur Dam is in Maharashtra, forming the Isapur Reservoir on the Penganga river (also known as Yeldari Dam).
– Kangsabati Dam (or Mukutmanipur Dam) is in West Bengal, creating the Kangsabati Reservoir.
These locations are primarily recognized for their large water bodies created by dams, used for irrigation, water supply, and sometimes power generation. They are not commonly known for newly discovered uranium deposits, being part of tropical rainforests (as they span different climatic regions of India), or extensive underground cave systems. Thus, the commonality is that they are sites of water reservoirs.

Among the options provided, the linking of the Godavari and Krishna rivers is a prominent project that was recently undertaken and completed. Specifically, the Pattiseema Lift Irrigation Project in Andhra Pradesh connects the Godavari river to the Krishna river via the Polavaram Right Main Canal, transferring Godavari water to the Krishna basin. This project was completed and commissioned in 2015-2016. Other options do not represent significant, recently completed river linking projects of this scale in India.
The Godavari-Krishna river linking (via the Pattiseema Lift Irrigation Project) is a recently completed inter-basin water transfer project in India.
River inter-linking projects in India are large-scale engineering proposals aimed at connecting rivers through reservoirs and canals to redistribute water, addressing issues like regional water shortages and flood control. The Ken-Betwa link is another significant river linking project that has been discussed and is under implementation process, but the Godavari-Krishna link (Pattiseema) was completed earlier among the options provided.

– The Salal Dam is a run-of-the-river hydropower project on the Chenab River in Jammu and Kashmir.
– The Rana Pratap Sagar Dam is built on the Chambal River in Rajasthan.
– The Tehri Dam is the highest dam in India, built on the Bhagirathi River, a major tributary of the Ganges, in Uttarakhand.
These projects are significant hydroelectric power generation facilities in India, contributing to the energy needs of the respective regions. Matching dams/projects with their corresponding rivers is a common type of question in geography sections of competitive exams.

The correct answer is Mayurakshi project is a joint venture of Odisha and West Bengal.
Let’s examine each statement:
A) Machkund project: This is a hydroelectric project on the Machkund River, a tributary of the Godavari. It is a joint venture between Andhra Pradesh and Odisha (formerly Orissa). This statement is correct.
B) Parambikulam Aliyar project: This is a complex multipurpose project involving inter-basin transfer of water from rivers in the Parambikulam and Aliyar basins (in Kerala and Tamil Nadu respectively) to serve irrigation and power needs in Tamil Nadu. It is a joint venture between Kerala and Tamil Nadu. This statement is correct.
C) Mayurakshi project: This project is based on the Mayurakshi River, which flows through Jharkhand and West Bengal. The Massanjore Dam (also known as Canada Dam) on this river is located in Jharkhand, but built for the benefit of West Bengal. The benefits of the project primarily accrue to West Bengal (irrigation and power). Odisha is not a beneficiary or partner in this project. This statement is incorrect.
D) Chambal Valley project: This is a series of dams on the Chambal River. Key dams include Gandhi Sagar Dam (Madhya Pradesh), Rana Pratap Sagar Dam, Jawahar Sagar Dam, and Kota Barrage (all in Rajasthan). It is a joint venture benefiting Madhya Pradesh and Rajasthan. This statement is correct.
The Mayurakshi project primarily involves West Bengal and benefits from the Massanjore dam located in Jharkhand.

2. Sabarigiri is a major Hydroelectric Project in Kerala, located near the famous Sabarimala temple, utilizing the Pamba and Kakki rivers.
3. Ghatprabha Project in Karnataka is primarily an irrigation project built on the Ghataprabha River, a tributary of the Krishna. It includes the Hidkal dam.
4. The Ramganga Dam project at Kalagarh, Uttarakhand, on the Ramganga River, is a multipurpose project providing irrigation, hydroelectric power generation, and flood control.
Understanding the purpose of major dams and projects is important for Indian geography. Hydroelectric projects generate electricity from water, thermal power stations use fossil fuels (coal, gas, etc.), irrigation projects supply water for agriculture, and multipurpose projects serve multiple aims like power generation, irrigation, flood control, navigation, etc.
