Srisailam Reservoir Inflows Cross 2 Lakh Cusecs, Storage 100 TMC
Imagine a very big bathtub for a river, called the Srisailam reservoir.
Heavy rain in two Indian states made a lot of extra water flow into it.
So much water arrived that the reservoir passed an important number called 100 TMC, which is a way to measure enormous amounts of water.
The water level keeps rising and may fill the reservoir within a week.
When a reservoir is very full, some water is sent through machines that make electricity.
Officials are being careful, though, because they worry the rain could stop.
They fear using too much water to make electricity and then running short.
The officials say their first job is to make sure everyone has safe drinking water.
After that, they will share water with farmers for their crops.
Two nearby regional governments also disagree about how much water each one should take.
Inflows from the upstream Jurala project surged past 2 lakh cusecs (reported at 2.45 lakh and 2.08 lakh cusecs at 10 am on Tuesday) following heavy rain in Karnataka and Maharashtra.
Water storage crossed the 100 TMC ft mark, though reports differ on the exact figure: 118.62 TMC ft versus 101.92 TMC ft, against a gross capacity of 215.807 TMC ft.
The water level reached 863.90 feet against a full reservoir level of 885 feet, with about 18.5 TMC ft of water being added daily.
Article reports conflict on power generation: one says generation began at the Left Bank Hydroelectric Power Station releasing 4,267 cusecs to Nagarjuna Sagar, while another says officials await a policy decision.
Andhra Pradesh alleged Telangana has drawn 1,600 cusecs daily since July 25 for Mahbubnagar district needs, while officials said drinking water security comes before irrigation releases.
- Who
- Reservoir officials, including superintendent engineer M. Venugopal Reddy, and the governments of Andhra Pradesh and Telangana.
- What
- Heavy inflows from the upstream Jurala project pushed Srisailam reservoir storage past the 100 TMC ft mark, prompting decisions on hydel power generation and water releases.
- When
- Reported on a Tuesday, when inflows stood at 2.08 lakh cusecs at 10 am; Telangana's disputed drawing is said to have run since July 25.
- Where
- Srisailam reservoir, involving the states of Andhra Pradesh and Telangana; upstream releases originated from heavy rain in Karnataka and Maharashtra.
- Why
- Heavy rainfall in Karnataka and Maharashtra triggered large releases from the Jurala project, causing the surge in inflows to Srisailam.
Pro-Action View
Caution-First View
Hydel power generation
Pro-Action View
Generation should proceed using the heavy inflows; power generation has been carried out even when storage was around 50 TMC in the past.
Caution-First View
Officials should wait for clarity on sustained inflows; running both hydel projects at full capacity consumes about 6 TMC ft daily, and El Nino conditions make rainfall unreliable.
Inter-state water use
Pro-Action View
Andhra Pradesh says Telangana drawing 1,600 cusecs daily since July 25 is a matter of concern.
Caution-First View
Telangana has been utilizing the inflows from day one to meet irrigation and drinking water needs of Mahbubnagar district.
Release priority
Pro-Action View
Farmers are cheered by rising levels and expect irrigation releases for projects such as Handri Neeva, SRBC, Telugu Ganga, and Galeru-Nagari.
Caution-First View
Officials say drinking water security is the priority; irrigation releases will only follow later, depending on storage and rainfall conditions.
