	Wetland/Lake	Location
1.	Hokera Wetland	Punjab
2.	Renuka Wetland	Himachal Pradesh
3.	Rudrasagar Lake	Tripura
4.	Sasthamkotta Lake	Tamil Nadu

How many pairs given above are correctly matched?

The correct answer is Only two pairs.

Key Points

Hokera Wetland:

• It is located in the northwest Himalayan biogeographic province of Kashmir, the back of the snow-draped Pir Panchal. Hence, Pair 1 is not correctly matched.
• Hokera wetland is only 10 km from the scenic paradise of Srinagar.
• A natural perennial wetland contiguous to the Jhelum basin, it is the only site with the remaining reedbeds of Kashmir.

Renuka Wetland:

• It is located in Himachal Pradesh. Hence, Pair 2 is correctly matched.
• A natural wetland with freshwater springs and inland subterranean karst formations, fed by a small stream flowing from the lower Himalayan to the Giri river.
• The lake is home to at least 443 species of fauna and 19 species of ichthyofauna representative of lacustrine ecosystems.

Rudrasagar Lake:

• It is located in Tripura. Hence, Pair 3 is correctly matched.
• It is a lowland sedimentation reservoir, fed by three perennial streams discharging to the River Gomti.
• It is an ideal habitat for IUCN Red-listed Three-striped Roof Turtle (CR).

Sasthamkotta Lake:

• It is the largest freshwater lake in Kerala, situated in the Kollam district. Hence, Pair 4 is not correctly matched.
• River Kallada had a unique replenishing system through a bar of paddy fields.
• The lake is now depleting due to the destruction of the replenishing mechanism.

Hence, Option 2 is correct.
