Indus River System Geography

The Indus basin is a transboundary river system originating in the Tibetan Plateau and draining through India, Pakistan, Afghanistan, and China, making its water-sharing arrangements strategically significant beyond bilateral India-Pakistan relations.

Key details
  • The Indus originates near Lake Mansarovar in Tibet, flows through Ladakh, and enters Pakistan before emptying into the Arabian Sea near Karachi.
  • Key tributaries covered under the treaty: Jhelum and Chenab (western rivers, via Jammu and Kashmir); Ravi, Beas, and Sutlej (eastern rivers, via Punjab).
  • Pakistan is estimated to depend on the Indus system for roughly 80% of its irrigated agriculture, which is the primary reason abeyance is viewed by India as significant leverage.
