This year’s southwest monsoon has smashed all previous records in the realisation of Cauvery water by Tamil Nadu.
The total realisation is likely to cross the 500 tmc ft mark by May 2023.
It was declared by the Central Water Commission (CWC).
Only the CWC’s calculations are considered because the reference point for measurement is the Biligundulu station, which is being maintained by the agency.
Since 1974-75, the highest annual realisation was 455.4 tmc ft in 1975-76.
It is the period of which was taken into account by the Supreme Court-constituted high-level technical team in 2016.
The total approximate amount of realisation for 1978-79 was 400.6 tmc ft; 1980-81-442.9 tmc ft; 1981-82-417 tmc ft; and 2018-19-405.4 tmc ft.
In the present year, the aggregate realisation crossed the 450-tmc ft mark in just four months.
In those four years, southwest monsoon yielded approximately 291 tmc ft, 342 tmc ft, 299 tmc ft and 345 tmc ft respectively.
