What happened

Some supportReported by 2 outlets

Reduced freshwater flow in the Ganges river system is occurring due to engineering pressures and operations at the Farakka Barrage. This has led to a decline in Hilsa fish catch in Bangladesh, which fell to roughly 500,000 tonnes in 2023–24, down from a record of 5.71 lakh tonnes in 2022–23. The Farakka Barrage diverts Ganges water to Kolkata to flush sediment from the port.

Why it matters

Some supportBrind's analysis of the reports

The Farakka Barrage is a critical piece of infrastructure that dictates water flow in the Ganges system, impacting the environment and livelihoods of Bangladesh. This situation occurs as the treaty governing Ganges water-sharing between India and Bangladesh nears its expiration in December 2026.
