The river Manimuthar is a major tributary of the Tamiraparani. Manimuthar river originates on the eastern slopes of western ghats in Tirunelveli district. It arises from the dense forest at Senkutheri in Ambasamudram taluk at the height of about 1300 m. from MSL. The tributaries of the Manimuthar are the Keezha Manimuthar (lower or eastern Manimuthar) and the Varattar. The river runs from its source for a distance of 9 km. and confluences with the Tamiraparani near Kallidaikurichi. The river contributes a lot, as tributary, to enhance the water level of Tamiraparani as it is always in full spate and perennial.
