This beautiful lake totally justifies its presence in this beautiful national park. This artificial lake adds beauty to the Periyar National Park and glorifies the look of this national park. This beautiful lake was established in the year 1895, also the area was announced as a forest reserve with the name given Periyar Lake Reserve in the year 1899. It was established during the construction of the dam across the magically beautiful river Mullaperiyar.
So the answer is the beauty it presents and also the presence of water birds in this river that you can witness during a boat safari. This river comes under the protected area and also it provides conservation of plants, birds, animals, and fishes. So this lake is not like any other lake, it has its own agenda and beauty of course. Soo can even witness some rare, endemic, and incredible species there as well.
