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?

Let's analyze each statement: 1. Jhelum River passes through Wular Lake: This statement is correct. Wular Lake is one of the largest freshwater lakes in Asia, located in the Bandipora district of Jammu and Kashmir. The Jhelum River flows into the lake and then drains out, playing a crucial role in its hydrology. 2. Krishna River directly feeds Kolleru Lake: This statement is incorrect. Kolleru Lake is a large freshwater lake in Andhra Pradesh, located between the deltas of the Krishna and Godavari rivers. It is primarily fed by seasonal rivers like Budameru, Tammileru, and Ramileru, and is also connected to the Krishna and Godavari river systems through various channels, but the Krishna river does not directly feed it. 3. Meandering of Gandak River formed Kanwar Lake: This statement is incorrect. Kanwar Lake (Kabar Taal) is Asia's largest freshwater oxbow lake, located in Bihar. It was formed by the meandering of the Burhi Gandak River, not the Gandak River itself. Therefore, only statement 1 is correct.
