Question

Consider the following pairs:
1. Harike Wetlands - Confluence of Beas and Satluj/Sutlej
2. Keoladeo Ghana National Park - Confluence of Banas and Chambal
3. Kolleru Lake - Confluence of Musi and Krishna
Which of the above pairs is/are correctly matched?

IASCODEX · Accepted Answer

Correct Option: A. 1 only

Strategy: Focus on locating key river confluences in the pairs. Harike Wetland is accurately matched with the Beas and Sutlej convergence. Keoladeo Ghana is a man-made wetland, not a river confluence—Banas and Chambal never meet there. Kolleru Lake is a freshwater lake between the Godavari and Krishna delta, not at the confluence of Musi and Krishna. Therefore, only the first pair is correct.

Key Info: Harike Wetland is the largest wetland in northern India and was formed at the confluence of the Beas and Sutlej rivers near the town of Harike in Punjab. It was created after the construction of headworks in 1952 and is a Ramsar site of international importance, supporting numerous migratory bird species and significant aquatic biodiversity.

Keoladeo Ghana National Park, located in Bharatpur, Rajasthan, was originally a man-made wetland developed to serve as a waterfowl hunting ground; it draws its water from the Gambhir and Banganga rivers, unrelated to the Banas or Chambal rivers. The park is not located at the confluence of any two rivers and is now a UNESCO World Heritage Site and Ramsar wetland.

Kolleru Lake is a large shallow freshwater lake in Andhra Pradesh, situated between the deltas of the Krishna and Godavari rivers, not at a river confluence. It has seasonal inflows mainly from the Budameru and Tammileru, with no direct Musi-Krishna confluence. Both Keoladeo and Kolleru are noted bird habitats but do not fit the confluence descriptions given in the pairs.
