The 111th meeting, which began on Sunday, was attended by a six-member Pakistani delegation led by its Commissioner for Indus Waters Mirza Asif Beg.
In recent years, differences over sharing river waters have emerged as a key irritant between the two countries. Pakistan has charged India with violation of the Indus Waters Treaty, an allegation denied by India.
Pakistan's ruling PML-N had also brought up the issue of "water management" in the context of relations with neighbouring countries in its manifesto.
