Flash Flooding in Teesta River Basin (June 23-30, 2026): Impact in Lalmonirhat and Surrounding Districts

Persistent flash flooding occurred in the Teesta River basin from June 23 to June 30, 2026, driven by upstream rainfall and water releases from the Gajoldoba barrage. The event caused significant flooding across 8 districts and 5 upazilas, specifically impacting Lalmonirhat, Nilphamari, Rangpur, Gaibandha, Kurigram, Sunamganj, Sylhet, and Netrokona. Approximately 5,500 families and 2,000 people were affected, with extensive damage reported to homes, rural infrastructure, roads, char lands, and six schools. The crisis led to severe sanitation and clean water shortages. By June 30, water levels began receding, and the local administration initiated relief efforts including 220 metric tons of rice and 550,000 BDT in aid.
