UPSC Prelims 2023 Question:

Consider the following statements

1. Jhelum River passes through Wular lake.
2. Krishna River directly feeds Kolleru Lake.
3. Meandering of Gandak River formed Kanwar Lake.
   
   

How many of the Statements given above are correct?

Explanation:

• Wular Lake is the largest freshwater lake in India and is located in Jammu and Kashmir. It lies at the north end of the Vale of Kashmir, 20 miles (32 km) north-northwest of Srinagar. The lake controls the flow of the Jhelum River, which traverses it. So, statement 1 is correct.
  
  
• Kolleru Lake is fed directly by water from the seasonal Budameru and Tammileru streams and is connected to the Krishna and Godavari systems by over 68 inflowing drains and channels. It serves as a habitat for migratory birds. Thus, the Krishna River does not directly feed Kolleru Lake. So, statement 2 is not correct.
  
  
• Kanwar Jheel is part of an extensive floodplain wetland complex formed in the lower reaches of Gandak – Kosi interfan in North Bihar. Located at a distance of 21 km from Begusarai town. Kanwar is the largest of a series of shallow permanent and ephemeral wetlands formed in the depression between River Burhi Gandak and the palaeochannel of River Bagmati. It has not been formed due to the meandering of the Gandak River. So, statement 3 is not correct.
  
  

Therefore, option (1) is the correct answer.
