India on Sunday (Aug 24) informed Pakistan about the flood situation in the Tawi river via its Indian High Commission to the Pakistan Foreign Ministry. This is the first time India has used this mechanism to alert Pakistan about the flood situation via the High Commission.
This was not done through the Indus Waters Treaty, which remains in abeyance. The Indus Waters Treaty has been in abeyance after the Pahalgam terror attack. Ideally, under the Indus Waters Treaty, information is shared through the Indus Water Commissioner.
