Assam Floods Linked to Illegal Mining Along Assam‑Nagaland Border
Heavy monsoon rains in July 2026 caused record water levels in Upper Assam, inundating the Sivasagar and Charaideo districts. Rivers such as the Disang surged to 96.49 m at Nangalamaraghat, surpassing the 1998 record, while blocked culverts and inadequate road drainage amplified the damage.
The Assam Sammilita Mahasangha, led by executive president Matiur Rahman, alleges that years of illegal stone and coal mining along the Assam‑Nagaland border disrupted the Dikhow river’s flow, intensified soil erosion, and created abandoned pits that collapsed into the river during the rains. The group cites a 2019 Public Interest Litigation filed by former Nazira MLA Debabrata Saikia, which prompted the Gauhati High Court to order a Mines and Minerals Task Force and a river‑conservation committee—orders that remain unimplemented. The Mahasangha says the disaster has killed at least 48 people, left more than 100 missing, and caused extensive property and livestock loss.
Relief efforts have been hampered by shortages of drinking water and allegations of political middlemen diverting aid. The organization calls for immediate cessation of illegal mining, enforcement of court directives, and transparent distribution of relief supplies.
