Thol Lake was originally constructed as an irrigation tank in 1912. Over time, its ecological significance became apparent, attracting a large number of birds. Recognizing its importance as a bird habitat, the area was declared a sanctuary in 1988. Since then, efforts have been made to conserve and manage the lake and its surrounding environment to ensure the continued well-being of the avian population. The sanctuary has become a crucial site for migratory birds, providing them with a safe and abundant feeding ground during their long journeys. Ongoing conservation efforts aim to maintain the delicate balance of the ecosystem and protect the sanctuary from human encroachment and pollution.
