Consider the following events related to river transport on the Brahmaputra in Assam:
On October 5, 2026, the barge DLB Patkai left Bogibeel Terminal with 540 tonnes of Namrup methanol for Pangaon port near Dhaka. It is the first international cargo from eastern Assam since Partition, made possible by new Customs and Immigration complexes at Bogibeel and Dhubri.
UPSC often tests the historical layering behind a current event, here a colonial trade corridor, its post-Partition collapse and its later revival. A chronology question checks whether the aspirant understands why a 1972 treaty and a 1988 waterway did not restore cargo until 2026.
NW-2 is the 891 km Sadiya-Dhubri stretch of the Brahmaputra, declared in 1988 and administered by the Inland Waterways Authority of India.
Upper Assam's river outlet was closed in layers: Partition (1947), the 1950 earthquake, the ghat's closure (1956) and the 1965 suspension of cross-border river trade.
The 1972 India-Bangladesh protocol underpins the route, but international cargo resumed only after customs posts were set up at Bogibeel and Dhubri.
