River Flow Explanation:

From Brahmagiri range,the river flows into Deccan Plateau and reaches Shivanasamudram in Mandya district of Karnataka.

# At Shivanasamudram,the river branches into two parts and falls through a height of91m in a series of falls and rapids.

# One branch forms Srirangapatna Island and other forms a waterfall called as Shivanasamudra waterfall.

# The two branches join after the fall and flow through a wide gorge Mekadatu(Goats Leap) and continues its flow to form boundary between Karnataka and Tamilnadu.

#When Cauvery river reaches Hogennekkal Falls ,it takes southery direction and enters Mettur Reservoir.

# Bhavani joins from right side below Mettur Reservoir.
