The current irrigation year will go into Cauvery records as the worst the Tamil Nadu having received the lowest quantum of water from Karnataka since the Cauvery Water Dispute Tribunal's interim award of 205 tmcft given in June 1991. As the quantum prescribed by the tribunal for May is 2.01 tmcft, the total realisation for the current year would be only about 162 tmcft, according to PWD sources.
