Dam levels in TN are poor & with great August ahead, levels are expected to improve


Though Tamil Nadu has got huge excess rains in this South monsoon, it does not reflect the dams levels in Tamil Nadu, it was in the leeward side of the Tamil Nadu which had got amazing rains in this season for past two months. The dam catchments areas in Valparai have got some rains and has  some decent storage in the Coimbatore dams such as Sholyar, Aliyar and Parambikulam belts. But the Bhavani basin in Nilgiris it was total flop till now, dams such as Upper Bhavani, Avalanche, Mukurthy etc have all got very less rains and has very bad storage levels. Not even single 100 mm in these season so far was surprise. Strong monsoon winds are needed in these areas to penetrate into the locked ghat valleys and when it does, there will be massive rains and will generate inflows. Kanyakumari dam levels are ok with excellent rains in May and early June rains. August looks good, there will be huge improvement in the next month update for sure.

Mettur dam levels depends upon the rains in the upper catchment in Kodagu and Wayanad and the dams in Karnataka are filling up fast, it will be just matter of time before good inflows start to come to Mettur dam with superb August ahead.
