Lower Anaicut

The Lower Anaicut or Anaikkarai is a dam and bridge built on the Kollidam (the northern distributary of Kaveri River) in the Indian state of Tamil Nadu.

It was built in 1902 by the colonial administration of the Madras Presidency for irrigating the erstwhile South Arcot district.

[1][2][3] It has a shutter and sluice system that distributes the Kollidam water into various waterways.

10 tmcft water is allocated for the minimum environmental flows in the dowm stream of the Lower Anaicut.

Another 4 tmcft is identified as unavoidable wastage to the sea from the Lower Anaicut/river basin.
