Dantiwada Dam, constructed on the Banas river, is located in which Indian state?

Introduction / Context:
Large dams are key pieces of water resource infrastructure and often appear in Indian geography questions that test knowledge of which river and state each dam is associated with. Dantiwada Dam is one such structure, primarily used for irrigation and flood control. Knowing that it is located in Gujarat on the Banas river helps students connect river basins, states and multipurpose projects together.

Given Data / Assumptions:

- The structure mentioned is Dantiwada Dam. - It is built on the Banas river. - The question asks in which state this dam is located. - Options include Gujarat, Sikkim, Andhra Pradesh and Telangana.

Concept / Approach:
Indian dams are usually associated with particular river systems and states. Dantiwada Dam lies in the Banaskantha district of Gujarat and is constructed across the West Banas river. It is part of irrigation and flood control measures in a semi arid region. The approach is to recall that Banaskantha itself is a district of Gujarat and that the name already hints at the Banas river in that state, not at rivers in Sikkim or the southern states listed in other options.

Step-by-Step Solution:

Verification / Alternative check:
Verification can be done by consulting lists of dams by state in school atlases or irrigation department summaries. These lists place Dantiwada Dam under Gujarat, often highlighting its role in irrigating nearby agricultural areas and mitigating floods. Maps showing the Banas river flowing through northern Gujarat further support the association, since none of the other states listed in the options contain this river under the same name.

Why Other Options Are Wrong:
Sikkim has hydropower projects on Himalayan rivers such as Teesta but no Dantiwada Dam. Andhra Pradesh is associated with dams like Srisailam and Nagarjuna Sagar on the Krishna river system, not with Dantiwada on the Banas. Telangana also shares some large dams on Krishna and Godavari but does not host Dantiwada Dam. None of the above is incorrect because Gujarat clearly matches the known location of Dantiwada Dam.

Common Pitfalls:
Students sometimes confuse the Banas river of Rajasthan and Gujarat with similar sounding names elsewhere or assume that any dam on Banas must be in Rajasthan. Another mistake is to guess southern states when they see unfamiliar dam names, simply because many big dams are located there. Careful study of river basin maps and state wise dam lists is the best way to avoid these confusions in geography exams.

Final Answer:
Dantiwada Dam on the Banas river is located in the state of Gujarat.
