Evaporation and dip in inflows cited as reasons

With the mercury level rising, the water level in the Krishnaraja Sagar (KRS) in Mandya district is coming down rapidly owing to the increase in the evaporation rate and the decrease in the inflows.

The storage level of KRS, built across the Cauvery near Srirangapatna, was 110.28 ft., as against the full reservoir level of 124.80 ft., at 6 a.m. on Sunday.

According to Cauvery Neeravari Nigama Ltd. (CNNL) officials, the KRS was receiving just 154 cusecs of water as against the outflow of 708 cusecs.

There was just 20.09 tmcft. of water as against the maximum storage capacity of 45.05 tmcft., said the officials.

The temperature at the reservoir area was 36 degrees Celsius at 12.30 p.m. The temperature has been hovering between 34 and 36 degrees Celsius in the reservoir area over the last two weeks.

Thus, the rate of evaporation has been between 150 and 250 cusecs a day, a senior official in the Department of Irrigation said.

The KRS had 120.97 ft. of water, slightly nearer the FRL, on January 1 this year.

Water for festival

However, a huge quantum of water was released from the KRS for several days to revive the dried Gaganachukki waterfalls, near Malavalli, for organising ‘Jalapathotsava’ (festival of waterfalls) on January 18 and 19.

Moreover, the obligation to discharge water to Tamil Nadu has also caused depletion in the water level of KRS, he said. Nevertheless, the situation is slightly better when compared to last year when the water level at KRS was 102.90 ft.

Dead storage

The mercury level will definitely increase from mid-April. The KRS level might reach the dead storage [of 74 ft] by mid-May if the monsoon delays this year as the reservoir storage will be split into water for Tamil Nadu, standing crops in the delta region in Mandya district, and for drinking purposes of Bengaluru, Mysuru and Mandya districts, said the official.
