Mettur Dam – The biggest Dam in Tamil Nadu. Good storage in Mettur Dam for 3rd year in row. Lot of water has been released from Mettur for irrigation, else it would have touched 120 feet long back. More rains expected in catchment areas in October. Hence, it will continue to get good inflows.
Bhavanisagar Dam – The 2nd biggest dam continues to have more than 85% storage for over 2 months now.
Coimbatore Dams – most of the Dams in the district are near full level. The Top 3 dams Parambikulam, Sholayar and Aliyar are 100% full at mid-Ocotber.
Nilgiris Dams – Here too most of the dams are at close to full level with good September in the catchment areas.
Kanyakumari Dams – The two big dams Pechiparai and Perunchani are both nearly 85% full. The third biggest dam in Kanyakumari which is Kodayar is 100% full.
Tirunelveli Dams – Good storage in Papanasam and other small dams. While Manimuthar has very less storage. Manimuthar gets water from Manjolai belt from North East Monsoon. Remember Manjolai is the wettest place in India in North East Monsoon with over 2500 mm falling in these 3 months.
Theni Dams – Periyar Dam has 60% storage while Vaigai has 50% of water. With NEM on the corner, Vaigai can expect more water from its catchment rather than from Periyar Dam.
Chennai Dams – With so much water from Pennar / Krishna available in Kandaleru / Somasila, we are already having 5 tmc of the total capacity of 11 tmc of water. We are going into 2021 without a drought even if NEM fails in the worst case. In positive case, with good rains, we can see water overflowing from all the 4 dams of Chennai.
Tiruvannamalai Dams – With poor SWM monsoon in the Then Pennai dams of Sathanur Dam and Krishnagiri dams have less water.
I have tried my best to get maximum number of dams from various sources. If some of the Dams are missing, either they are very small one (less than 100 mcft or 0.10 tmc) or the data is not available in public domain.
