Srisailam water level drops as electricity use rises – The New Indian Express

Express press service

VIJAYAWADA: Srisailam Reservoir recorded a water level of 83.73 TMC on Monday, which is well below the corresponding one-day water level last year.

On the same day last year, the reservoir had 154.18 TMC of water. Two factors are thought to be behind the decline in storage this year, one being lower inflows compared to last year and the second being increased use for power generation.

According to the daily readings showing the condition of the canal, the inflow and outflow capacity of the reservoir levels available from the Department of Water Resources, in December and the last 17 days of January, Andhra Pradesh and Telangana have abstracted water in varying amounts for power generation at Right Bank Power Station and Left Bank Power Station.

In the past 17 days, compared to Telangana, Andhra Pradesh has drawn more water for power generation. The water released from the project for this 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 the two reservoirs are shared by sister states. In Nagarjuna Sagar, the water level on Monday was 274.09 CTM, 23.54 CTM higher than the corresponding day last year (250.55 CTM).

Although there was no influx to the Srisailam project, the influx to Nagarjuna Sagar as of Monday was at a discharge rate of 9,437 cusecs. According to sources, the use of water in various projects on Krishna and its tributaries in upper Andhra Pradesh has increased significantly compared to last year. At the same time, the Srisailam project catchments in Kurnool district did not receive much rain compared to other places.

On the other hand, Pulichintala downstream of Nagarjuna Sagar has slightly more water compared to the previous year. To date, it has 41.24 TMC compared to 30.03 on the corresponding day last year.

According to water audit from June 1 to January 17, Andhra Pradesh has 338.02 TMC of water till date, of which 155.1 TMC of water is in reservoirs (Major, Medium and Minor ) and 165.37 TMC are groundwater. This hydrological year to date, the state has received inflows of 5,586.87 TMC as rainfall and 2,538.83 TMC as inflows from other states. No less than 2,829.9 TMC of water was lost through evapotranspiration, consumption including irrigation was 851.36 TMC, river flow was 2,780.6 TMC, while 1,325 .45 was the surface and underground flow.
