Hyderabad: Most reservoirs in the Krishna and Godavari basins in Telangana state have more water than previous years, just before the onset of summer. At others, the water is close to the levels seen in 2020.
The government is confident it can sail through this summer without facing drinking water shortage either in the city or in the districts.
The good storage is the result of heavy rains received during the southwest monsoon that lasted till October. The state received 1,259.7 mm of rainfall from June 1, 2020, against the norm of 852.8 mm, an increase of 48 per cent. In the GHMC limits, the total was 1221.1 mm against 723.5 mm usually, which is higher by 68.8 per cent.
Nagarjunasagar in the Krishna basin remains the major source of drinking water for the GHMC limits and south Telagnana districts. As on Saturday, the water level at Nagarjunasagar dam stood at 559.50 ft against the full reservoir level (FRL) of 590 ft. It has 231.22 tmc ft against gross storage of 312.05 tmc. The same day last year, it had 551.30 ft and 212.43 tmc ft.
In Srisailam dam, water stood at 867.30 ft againt 868.8 ft last year (FRL 885 ft) and the storage was 130.96 tmc ft against 138.93 tmc last year (total capacity 215.81 tm ft).
