Pachiparai Reservoir in Kanyakumari District TN, India is influenced by seasonally reversing monsoon and the characteristics of the water body influenced by riverine inflow. An effort to elucidate the spatial and temporal variation in the phytoplankton community was carried out. The observations were primarily made by during Jan 2004 – Dec 2004. Average phytoplankton abundance and primary production varied marginally during the period of study. Surface phytoplankton population showed seasonal variations and the abundance peaked during the beginning of North East monsoon (November). The inflow of water during the monsoon into the reservoir was the prime factor that influenced input of the nutrients and appeared to enhance the primary production. This study provides the details of the spatial and temporal variation and explores the implication and causative factors responsible for the dynamics of the phytoplankton populations.
