While 2.25 lakh cusecs was released into the Kollidam — 1.50 lakh cusecs from the Upper Anicut and 75,000 cusecs from the Grand Anicut — at 8 a.m.
It was a well thought-out decision to divert the surplus into the Kollidam without flooding the Cauvery, the Vennar or the Grand Anicut canal.
While the possibility of conveying the surplus water from the Kollidam through a new canal to Pudukottai district from the Grand Anicut can be explored, the river, with a width of 1.8 km, that runs for nearly 160 km should be left as a flood carrier, as its importance was demonstrated after 44 years.
After a gap of 40 years, the Kollidam river, the major flood carrier, was in spate, that too twice.
The Grand Anicut saw hectic activity on November 25 when 3.37 lakh cusecs of water had to be diverted into the Kollidam from it, one of the oldest dams in Asia, built by a Chola ruler several centuries ago.
