The Siruvani river, now in the limelight, is a tributary of the Bhavani river, which, in turn, forms part of the Cauvery basin. Taking the shape of a river at the foot of the Muthikulam falls in Palakkad district of Kerala, the Siruvani is joined by many streams such as Pattiar and Paambar. Flowing entirely within the limits of Kerala, the river runs for about 35 km before it drains into the Bhavani in Koodapatti in the same district. Rising in the Nilgiris district, Bhavani flows in Kerala before coming back to Tamil Nadu and finally joins the Cauvery in a town named after itself. Aimed at supplying 1.3 tmc feet annually to Coimbatore, the new dam was completed in the 1970s.
