The Netravati River (or Nethravathi River) has its origins at Gangamoola at Samse in
Chikkamagaluru district of
Karnataka,
India. It provides water supply to
Mangalore city. It merges with the
Kumaradhara River at
Uppinangadi before flowing to the
Arabian Sea.Earlier in the last century it was called as Buntwal River due to the important town of
Bantwal on its banks. A reference to the River Nettrawutti, as it is mentioned in the book can be seen in the "Gazetteer of Southern India", published in 1855, as unfordable during South-West
Monsoon. It has apparent breadth of about 200 yards with a bed encumbered by large rocky masses chiefly of horneblend rock, containing spangles of mica and small garnets. Sienites also occurs, fragments of a beautiful pegmatite with flesh coloured felspar are seen in the beds of rivulets. The Buntwal River is navigable by small country craft for many miles.
