Explanations:The question asks for the name of a dam situated in Odisha, a state in eastern India. To answer this question correctly, it is essential to have knowledge of the major dams located within the state of Odisha. The correct answer is Hirakud Dam, which is one of the most significant dams in India and is located on the Mahanadi River in Odisha.
Hirakud Dam is a massive earthen dam that stretches for about 25.8 kilometers, making it one of the longest dams in the world. It was constructed between 1945 and 1957 and is primarily used for irrigation, flood control, and power generation. The dam has a reservoir that can hold up to 743,000 acre-feet of water, which is crucial for the agricultural needs of the region. Additionally, the dam has a hydroelectric power plant that generates electricity for the state and surrounding areas.
Understanding the geographical context of dams in India is important for various competitive examinations, particularly those related to geography and general knowledge. It is crucial to know the specific locations of major dams within each state to avoid confusion with dams located in other states. For example, Rana Pratap Dam is located in Rajasthan, Koyana Dam is in Maharashtra, and Kallania Dam is in Himachal Pradesh. These dams, while significant in their respective states, are not relevant to the question about Odisha.
In summary, Hirakud Dam is the correct answer because it is the major dam located in Odisha, playing a vital role in the state's water management and power generation. This knowledge is essential for students preparing for competitive examinations that test geographical and general knowledge about Indian states and their landmarks.
