The Indus River is one of the mightiest rivers in Asia, originating in the glaciers of Tibet near Lake Mansarovar and carving a dramatic arc through Ladakh, Gilgit-Baltistan, and Pakistan before draining into the Arabian Sea. Its vast basin sustains five major tributaries — Sutlej, Beas, Ravi, Chenab, and Jhelum — whose allocation between India and Pakistan was settled by the landmark Indus Waters Treaty of 1960. Understanding the Indus system is essential for SSC CGL Geography, as questions regularly appear on river sources, lengths, treaties, and tributary-river mapping.
