The South Pennar River (also known as Dakshina Pinakini in

Kannada and Thenpennai or Ponnaiyar or Pennaiyar in Tamil) is a river in India. Bangalore, Hosur, Krishnagiri,Kaveripattinam, and Cuddalore are the important cities on the banks of South Pennar river. This is the second longest river in Tamil Nadu, with a length of 497 km, after the Kaveri. Chandapura, Anekal, Hosur, Bagalur, and Chengam are the major industrial settlements on its banks. The river is severely polluted by industrial waste as it flows through major industrial areas in the eastern suburbs of Bangalore, Industrial parks of Hosur and Chengam.[citation needed

The river originates in the

Sathanur Dam with 7.3 Tmcft Gross Capacity is built near Tiruvannamalai. Moongilthuraipattu Sugar Factory is also situated on the bank of river.[citation needed
]

The river is dry for the most part of the year. Water flows during the monsoon season when it is fed by the south-west monsoon in catchment area and the northeast monsoon in Tamil Nadu. However this water flow raises the water table throughout the river basin and feeds numerous reservoirs/tanks.

The old river Dakshina Pinakini does not exist anymore.[2] Substantial part of

Varthur Lakes and other channels.[3]

The sand build of the river is quite impressive, suggesting that it may have been a perennial river with much larger water flow in the past. Mention of the river is found in

]

This river is now looted for its rich availability of sand. As the water flow will be only in monsoon seasons, the river is dry in remaining parts of the year.[citation needed]
