Severe Flooding in Assam Impacts Hundreds of Thousands

In the Upper Assam district of Jorhat, 18-year-old Saline Patro watched rain fall on the afternoon of July 19 from her home in Seleng Sumoni Pathar, a village on the banks of the Jhanji River. Within minutes, she heard the sound of rushing water and shouting. Knee-deep water surged into the house. Patro helped her elderly parents and younger brother reach higher ground, then turned back to salvage belongings. By the time she fought her way through the current, the house was gone. "We had a television, a cupboard and a sofa. Nothing was left. We couldn't even save a glass to drink water from," she told BBC Hindi from a relief camp (Google News India).

Patro’s village floods every year, but residents across the three worst-hit districts — Sivasagar, Charaideo and Jorhat — say they have never experienced inundation of this scale in their lifetimes (Indian Express). Floodwaters reached critical levels on July 19 and have spread daily since, submerging entire villages, vast agricultural tracts, and major towns such as Sivasagar under water well above chest level (Indian Express). As of July 28, the Assam State Disaster Management Authority estimated the affected population at seven lakh across 856 villages in 12 districts, with at least 66 lives lost in roughly a week (Indian Express). The authority recorded 58 deaths since Monday, including six children, and warned the toll would likely rise as the full extent of destruction unfolds (Indian Express). More than 1.15 lakh people are in relief camps, while the National Disaster Response Force, Army, State Disaster Response Force, Fire & Emergency Services and local administrations have evacuated around 4,455 people by boat (Indian Express).

The government initially attributed the disaster to a "cloudburst" in Mon district, Nagaland, on July 19. A scientist at the Meteorological Centre Kohima, however, told The Indian Express the area recorded 137 mm of rain over eight to nine hours — heavy rainfall, but not a cloudburst, which the India Meteorological Department defines as more than 100 mm in one hour (Indian Express). That spell also triggered landslides in Mon that killed nine people (Indian Express). Chief Minister Himanta Biswa Sarma said districts in Nagaland and Assam received rainfall between 435% and 490% above normal over the period, causing rivers to rise at unprecedented speed (Google News India). As of Friday, the tributaries Dikhow in Sivasagar, Disang at Nanglamoraghat and Dhansiri at Numaligarh were all flowing at "severe flood situation" levels (Indian Express).

Relief operations are hampered by the aftermath of the deluge. Sarma said Friday the administration had yet to reach around 30% of areas in Nazira Assembly constituency and 20% in Sivasagar constituency, both in Sivasagar district, even after water levels receded (Indian Express). Receding waters left behind layers of sediment several feet high, making access by foot or vehicle difficult (Indian Express). The government has yet to reach more than 50,000 people for relief (Indian Express). Chief Secretary Ravi Kota has deployed officials to worst-hit districts to speed up relief and restoration, prioritising supply of materials and restoration of essential services (Google News India).

Assam lies on the vast floodplain of the Brahmaputra, fed by more than 50 tributaries descending from the Himalayas. Nearly 40% of the state is classified as flood-prone by the National Flood Commission (Google News India). During the monsoon, heavy rain swells the river; as it crosses the flat plains it deposits sand and silt, reducing carrying capacity and making flooding more likely. Experts say the situation has worsened over time due to upstream deforestation, ageing embankments and heavier rainfall driven by climate change (Google News India). Minister Pijush Hazarika described the current episode as the state's worst in six decades (Google News India). On July 21 alone, 21 people died in 24 hours, most swept away or drowned, while others perished in landslides and house collapses (Google News India). Around 40 people remain missing (Google News India). The full scope of the damage and the final casualty count remain uncertain as waters continue to recede and access improves.
