An investigation was undertaken to study the physicochemical characteristics, phytoplankton and fish fauna of three major deep lakes on the River Mahaweli: Kotmale, Victoria and Randenigala. These lakes were created mainly for hydroelectric purposes during the period 1984 to 1986. In all three lakes, thermoclines were present during most months of the year, but did not appear to be very stable. They tended to disappear during January - February but were well established in August - November. Fifteen species of blue-green algae were identified as well as 27 desmid species and 25 non-desmid green algae. Melosira granulata and M. undulata were the dominant diatom species. The family Cyprinidae dominated the fish fauna by number of species, but by biomass the exotic cichlids (tilapias) were dominant.
