Godavari River Management Board (GRMB) Meeting:

The GRMB meeting on August 13 will see Telangana submit the detailed project report for the Sita Rama Lift Irrigation Scheme (SRLIS) and Sitamma Sagar multi-purpose project.
- Lift irrigation is a method of irrigation in which water is not transported by natural flow, (as in gravity-fed canal) but is lifted with pumps or surge pools etc.
Sita Rama Lift Irrigation Project (SRLIS)- Telangana:
- SRLIS aims to supply water to 3.45 lakh acres of gap ayacut in the tail-end areas of the Nagarjunasagar Left Canal in Khammam, Bhadradri-Kothagudem, and Mahabubabad districts, and create new irrigation potential for 3.29 lakh acres by lifting 65.25 tmc ft of Godavari water.
- Sitamma Sagar, a multi-purpose project, aims to generate 280 megawatts of hydro-electric power, store 36.57 tmc ft of water, and irrigate 1.13 lakh acres in Yellandu, Pinapaka, and Wyra constituencies.

Krishna River Management Board (KRMB) Meeting:

KRMB will meet virtually on August 14 to discuss supplying drinking water to Chennai from the Srisailam project through the Pothireddypadu Head Regulator and Telugu Ganga Canal.
The inter-state agreement of 1976-77 allows drawing 1,500 cusecs (15 tmc ft total) from the Srisailam reservoir for Chennai’s water supply, with Maharashtra, Karnataka, Andhra Pradesh, and Tamil Nadu contributing 5 tmc ft each.
The Pothireddypadu Head Regulator was constructed with an 11,150 cusecs drawal capacity, later expanded to over 55,000 cusecs in 2006.

Current Water Drawal:

Andhra Pradesh has been drawing up to 26,000 cusecs (over 2 tmc ft/day) from the Pothireddypadu Head Regulator since July 27 due to surplus water in the Srisailam project.
Telangana is drawing up to 2,400 cusecs for the Kalwakurthy Lift Irrigation Scheme, and Andhra Pradesh has an additional 675 cusecs from the Malyala pump house since July 30.
Mahatma Gandhi Kalwakurthy Lift Irrigation Scheme (MGKLIS):
- It is a lift irrigation project on River Krishna located in Mahbubnagar district in the Indian state of Telangana.
- The lift canal starts from the backwaters of the Srisailam Dam near Kollapur.
- The gravity-driven, 100-kilometre-long canal provides cultivation for nearly 137,000 hectares (340,000 acres)in 300 villages located in constituencies of Kollapur, Wanaparthy, Nagarkurnool, Kalwakurthy, Jadcherla, and Achampet.
