Abstract
Neyyar Dam and Aruvikkara Dam are two major dam reservoirs located at Thiruvananthapuram District of Kerala State. Physicochemical parameters of water from these two dam reservoirs were studied and compared during pre-monsoon and monsoon period from April 2018 to July2018.Water samples were collected from different sampling stations of the reservoirs and analyzed as per standard methods of APHA (2012). Water from Neyyar dam shows maximum value of all physicochemical parameters compared to water from Aruvikkara dam in the present study period. Water temperature, Total Dissolved Solids, Total Suspended Solids, pH, free CO2, Biological Oxygen Demand and Total hardness were maximumin pre monsoon season and Turbidity, Productivity and Dissolved Oxygen were maximum in monsoon season at both sites. Present study reveal that water from Neyyar dam is more polluted than water from Aruvikkara.
