The river begins in the dense forest on a mountain peak 1,300 metres (4,300 ft) above sea level in Ex-Singampatti Zamindari, Ambasamudram taluk and flows 9 kilometres (6 mi) though small cataracts until it reaches the Tambaraparani River near Kallidaikurichi.
The tributaries of the Manimuthar are the Keezha River and the Varattar River. As a tributary, the Manimuther River adds a considerable amount of water to the Tamiraparani River as it seasonally is always in full.
In 1957, Manimuthar anicut was built across the river 3 kilometres (2 mi) before its juncture with the Tamiraparani.
