To see the impact of Acid mine drainage (AMD) in Patkai wetland near Tikak open cast mine of Margherita Sub-division , District Tinsukia, Assam, the hydro-biological characteristics were analysed for the year 2007-08. Physico-chemical characteristics revealed low D.O. (3.21 mg/l); high turbidity (25.19 NTU), hardness (83.15 mg/l); presence of heavy metals like Arsenic (0.038 mg/l) and Iron (0.18 mg/l) beyond permissible level in water and sediment soil. Aquatic diversity represents less
