Heavy discharge of water from upstream reservoirs like Krishna Raja Sagar (KRS) and Kabini Reservoirs has resulted in the famed Gaganachukki and Bharachukki waterfalls in Mandya-Chamarajanagar border swell to their maximum amid the riot of green and the mesmerising misty veil. 

The two branches (eastern and western) flow through deep ravines on either side of the island before plunging into two different places a few kilometres apart to form the Gaganachukki and Bharachukki waterfalls. Gaganachukki and Bharachukki waterfalls are together known as the Shivanasamudra Falls (also called Bluff). While Gaganachukki is in Malavalli taluk of Mandya district, Bharachukki comes under the jurisdiction of Kollegal taluk in Chamarajanagar district.
