Krishnagiri Reservoir (KRP dam) situated 7 kms outside of Krishnagiri town, halts and regulates the flow of the Thenpennai River. Located between Dharamapuri and Krishnagiri, KRP Dam provides drinking water for Krishnagiri and irrigates thousands of acres of surrounding farm land. Inaugurated in 1958, the dam harnesses the full potential of the Ponniar River. The KRP Dam, since the time it opened has been an oasis of lush landscaped gardens. The gardens offer a spot of tranquility far away from the hustle and bustle of city life.
It is very often for this reason that locals and tourists flock to the dam. The best season to visit the dam is between November and March, especially the post-monsoon season when rains fill the river to the brimming capacity. It is usually post-monsoon, that the flood gates are open, and one may experience the thunder of water rushing beneath your feet whilst standing on the dam. The dam is well connected by road; the nearest airport being Bangalore International airport and the nearest railway station is the Hosur railway station (5km).
