Mukkadal dam is built across the Vambaru River, 10 km from Nagercoil. It was built by Sree Chithira Thirunal Balarama Varma in 1945, the King of Travancore. The dam is constructed of clay and granite stones. The depth of water behind the dam is approximately 50 feet. The Mukkadal reservoir supplies water for Nagercoil Municipality, but ironically, not the people living near the dam, and it is also proposed to get water from here for Suchindrum and Kanyakumari. The dam and reservoir are surrounded by hills on three sides.
It is a scenic place, favored as a picnic location among local residents. The forest are highly enhancing with pleasant shoals, hill top forests, beautiful grasslands, panoramic valleys, top hillocks, singing streams, vast stretches of rubber plantations, valuable Teak plantations and excellent climate. Nobody should miss seeing the enchanted view of this place.
