Uttara Pinakini

Extracted from the Wikipedia article Penna River.
Etymology
Since the river flows in two streams, in both the north and south directions, it forms the shape of bow. Thus, this river gets the name of bow called Pinakini named after Pinaka, the bow of Nandishvara, the presiding deity of the Nandi hills at the origin of the river. The name of the river Penneru (alternatively Penner) is derived from the Telugu words పెను, penu, 'grand' and ఏఱు, ēṟu, 'river, stream, rivulet' or from నీరు, nīru, 'water'. It is also known as Uttara Pinakini in Karnataka.
