Only 17 tmcft live storage in Cauvery reservoirs

But the situation is far better when compared to last year

The combined live storage in all four major reservoirs in the Cauvery basin in Karnataka is just 17.154 thousand million cubic feet (tmcft) as against their full live storage capacity of 106.321 tmcft. Nevertheless, the situation is far better when compared to last year.

Krishnaraja Sagar (KRS) near Srirangapatna of Mandya district, Kabini near Heggada Devana Kote in Mysuru district, Harangi near Kushalnagar in Kodagu district, and Hemavati near Goruru in Hassan district are the four major reservoirs in the river basin.

Except KRS, the other three reservoirs had almost attained full reservoir levels during monsoon owing to heavy rain in their catchment areas.

According to statistics obtained from the gauging sections of the reservoirs concerned, the combined gross storage was 40.745 tmcft on Monday. Of that, the usable quantum (live storage) was merely 17.154 tmcft.

MLS capacity

The combined maximum live storage (MLS) capacity of all four reservoirs is 106.321 tmcft. The MLS of KRS is 45.051 tmcft, Kabini 15.67 tmcft, Harangi 8.5 tmcft, and Hemavati 37.10 tmcft.

Bengaluru and Mysuru are the major towns depending on KRS for drinking needs, while Hassan, Tumakuru and some other towns of Mysuru and Kodagu rely on the storages of Harangi and Hemavati. Kabini too quenches the thirst of surrounding areas apart from supplying water, along with KRS, to the neighbouring Tamil Nadu.
