The Brahmaputra River has once again raised concerns in Assam’s Dibrugarh district after fresh erosion damaged the historic Kohair No. 1 Spur, a key structure that has protected the town from floods and riverbank erosion for decades.
The erosion has occurred in the Maijan area, where strong river currents have weakened sections of the spur. The structure is linked to Dibrugarh’s main embankment and serves as an important defence against the Brahmaputra’s changing flow and flood threats.
The Kohair No. 1 Spur, constructed in 1955, is considered one of the oldest flood protection structures in the region. Its foundation stone was laid by India’s first Prime Minister Jawaharlal Nehru, adding historical importance to the structure.
Despite its crucial role in protecting Dibrugarh for more than 70 years, the spur has reportedly not received major scientific renovation or strengthening work. With increasing erosion pressure and ageing infrastructure, parts of the structure have become vulnerable.
Residents and local stakeholders have expressed concern that continued erosion could weaken the main embankment and increase the risk of flooding in the town, especially during the monsoon period.
They have urged the Assam government and the Water Resources Department to take immediate action, including scientific restoration, strengthening of the spur and implementation of a long-term erosion management plan.
Locals said that repeated requests for protecting the historic flood defence structure have not led to a permanent solution. They warned that timely intervention is necessary to prevent further damage and safeguard Dibrugarh from future flood threats.
