VIJAYAWADA: Srisailam reservoir on Monday recorded a water level of 83.73 TMC, which is far less than the water level on a corresponding day last year.

On the same day last year, the reservoir had 154.18 TMC of water. Two factors are said to be the reason for the less storage this year, one being lesser inflows compared to last year and the second increased use for power production.

According to the daily statements showing the status of the canal, reservoir levels capacity inflow and outflows available with the water resources department, in December and for the past 17 days of January, both Andhra Pradesh and Telangana withdrew water at varying quantum for power generations in the right bank powerhouse and left bank powerhouse. 

In the past 17 days, compared to Telangana, Andhra Pradesh drew more water for power generation. The water released from the project for the purpose ends up in Nagarjuna Sagar and is used for irrigation purposes. According to officials, there is no wastage of water as it would end up in another reservoir instead of Srisailam and both reservoirs are shared by the sibling states.
