For the third 12 months in a row, Tamil Nadu acquired a better amount of Cauvery water through the water 12 months 2020-21 (June-Might) than its quota.
In opposition to the 177.25 tmc ft (thousand million cubic toes) prescribed by the Supreme Court docket, the State realised 34 tmc ft in extra. As per the readings taken by the Central Water Fee in Biligundlu on the inter-State (Karnataka-Tamil Nadu) border, it netted round 211 tmc ft from June 2020 to Might 2021. However this was decrease than what Tamil Nadu acquired within the earlier two years — roughly 405 tmc ft in 2018-19 and 275 tmc ft in 2019-20.
This was the second time within the final 20 years that the State recorded, a minimum of for 3 consecutive years, larger realisation than its due. The earlier event was the interval from 2005-06 to 2011-12, when Tamil Nadu acquired a minimal of about 210 tmc ft in 2008-09 and a most of round 384 tmc ft in 2005-06. On a mean, the annual realisation throughout these seven years was round 269 tmc ft.
It stays to be seen whether or not the State’s luck would proceed this 12 months, too. There may be an expectation amongst water specialists within the State that the realisation through the 12 months can be good, contemplating the beneficial forecast on the southwest monsoon (June-September). Of the State’s general share of 177.25 tmc ft, the 4 months account for 123.14 tmc ft. The State depends on the Cauvery flows through the interval, because it doesn’t profit a lot immediately from the monsoon, although water is required for sustaining paddy, raised as a part of the short-term Kuruvai cultivation season, and commencing preliminary operations for the long-term Samba season.
Final 12 months, the State’s realisation through the southwest monsoon was 120.22 tmc ft, about 3 tmc ft in need of its share. However, as previously, it was through the northeast monsoon (October-December) that the State realised 75 tmc ft, although its quota was 41.35 tmc ft for the three months. Typically, the farmers of the Cauvery delta themselves will not be reliant on provides from the Mettur dam — the lifeline for agriculturists — through the northeast monsoon because the delta would even in any other case be reeling from heavy rain in these months.
The federal government is but to announce whether or not it could begin water provide from Mettur for irrigation on the scheduled date of June 12. As on date, the water stage stands at 97.22 ft (full stage: 120 ft), with storage being 61.3 tmc ft (capability: 93.47 tmc ft).
Although the Cauvery Water Administration Authority and Water Regulation Committee haven’t but knowledgeable the States of the Cauvery basin about their customary conferences firstly of the water 12 months, they’re anticipated to have their deliberations shortly.
