In West Bengal between Farakka feeder canal, Hooghly, and in two tributaries ropop Narayan and KosiIn Brahmaputra a total of 884 km was surveyed.

At 46 points in river Brahmaputra covering about 900 km distance in order to estimate the overall water quality of river Brahmaputra at different geographical locations and through out the survey period the water quality was assessed for Brahmaputra, Ganga and Hooghly. Boat based Bird survey awareness activities was carried out in Assam and West Bengal.
The study was carried out in two sectors for Brahmaputra with disturbed Goalpara and undisturbed Kaziranga National Park as a comparative study and in Hooghly Dolphin Abundance repeated survey (3 surveys) was carried out in Kaziranga and Goalpara Acoustic monitoring of dolphins in KNP, Golapra, Kulsi and Hooghly using CPODS.
