TN asks AP to suspend supply krishna water

The Krishna is the second largest east flowing river of the Peninsula.
The Krishna Basin extends over Andhra Pradesh, Telangana, Maharashtra and Karnataka having a total area of ~2.6 lakh Sq.km.
It is bounded by Balaghat range on the north, by the Eastern Ghats on the south and the east and by the Western Ghats on the west.
The Krishna River rises from the Western Ghats near Jor village of Satara district of Maharashtra at an altitude of 1,337 m just north of Mahabaleshwar.
The total length of river from origin to its outfall into the Bay of Bengal is 1,400 km.
The major part of basin is covered with agricultural land accounting to 75.86% of the total area.
The Krishna forms a large delta with a shoreline of about 120 km. The Krishna delta appears to merge with that formed by the Godavari and extends about 35 km into the sea.

About Krishna River Water Dispute:

Telangana and Andhra Pradesh share stretches of the Krishna and the Godavari and own their tributaries.
Both states have proposed several new projects without getting clearance from the river boards, the Central Water Commission and the Apex Council, as mandated by the Andhra Pradesh Reorganisation Act, 2014.
Andhra Pradesh alleges that Telangana has been drawing Krishna water from four projects — Jurala, Srisailam, NagarjunaSagar, and Pulichintala — for hydropower generation without approvals from the Krishna River Management Board (KRMB), an autonomous body that was set up after the bifurcation of the state, to manage and regulate the waters in the Krishna basin.
Telangana made it clear that it would not recognize Pothireddypadu project, which it alleges is being illegally constructed by the Andhra Pradesh government on Krishna river without any environmental clearances or allocation of even a drop of water to the project or any permission from the Green Tribunal.
