Once a mighty river that breathed life into northern Bangladesh, the Teesta now lies silent and broken, as its shimmering waters replaced by stretches of sand and its flow reduced to a faint memory for the millions who once depended on it.
The lifeline of two crore people lies gasping for breath as its waters vanishing, its banks eroding and its people left clinging to the memories of a river that once defined their existence.
Once a symbol of abundance, locals said, the Teesta today survives only in fragments, swelling briefly during monsoon, then receding into a barren desert of cracked sandbanks as winter approaches. The river’s decline has plunged the lives of Teesta basin residents into uncertainty, threatening their farms, fisheries and future.
By late October, the mighty Teesta had already dried up, long before the arrival of the dry season.
According to the Water Development Board (WDB), water flow at the Teesta Barrage point over the past 10 days averaged only 17,000 cusecs and continues to drop daily.
As the water disappears, so too does the livelihood of thousands. Farmers and fishermen along the Teesta’s banks say they are ‘dying along with the river’, WDB officials said.
Experts trace the beginning of this decline to the construction of India’s barrages at Gajoldoba near the Teesta’s entry point and at Doani in Lalmonirhat, which disrupted the river’s natural flow. Over time, its life-giving waters have been diverted through canals, leaving vast stretches of the riverbed dry.
Standing along the Teesta today, one can almost hear what locals describe as the ‘sigh of a dying river’, echoing across endless sand where strong currents once flowed.

The river’s navigability has dropped so drastically that irrigation under the Teesta Barrage — the country’s largest irrigation project — may face severe challenges in the coming dry season. Large parts of the riverbed now lie exposed, marked only by shallow pools and scattered dunes, according to the officials.
Originating from Himalayan glaciers, the Teesta flows through India’s Sikkim, Darjeeling and Jalpaiguri before entering Bangladesh through Dahagram in Lalmonirhat. From there, it meanders through Nilphamari, Rangpur and Gaibandha before merging with the Brahmaputra. Once, its fertile chars produced rice, jute, maize, sesame and vegetables in abundance, shaping the region’s agriculture, culture and livelihoods.
However, the construction of the Gajoldoba Barrage in 1983 disrupted Teesta’s natural course — triggering water shortages in dry months and devastating floods in monsoon.
According to WDB data, more than 20,000 families have been displaced by river erosion in the past decade, with nearly 35 kilometres of riverbank severely eroded. Recently, a 350-metre stretch of the Teesta bridge protection embankment at Mahipur in Lalmonirhat caved into the river.
In Kurigram’s Ulipur upazila, over 100 homes have been lost to erosion, while in Gangachara more than 50 families have been displaced. Hundreds more remain marooned in four villages of Rajarhat upazila.
For years, residents of northern Bangladesh have taken to the streets under the slogan ‘Save Teesta, Save North Bengal’.
Environmental activists and locals have recently organised human chains, sit-ins and torch processions across Rangpur division, demanding immediate action.
