The composition and chlorophyll a of phytoplankton was studied along with physico-chemical parameters of water in the man-made lakes of Universiti Malaysia Sarawak (UNIMAS), Kota Samarahan i.e., West Campus Lake (WC), East Campus Lake 1 (EC1) and East Campus Lake 2 (EC2). Sampling of phytoplankton was conducted in November 2014 and February 2015. A total of 17 genera of phytoplankton were recorded from these lakes in November 2014 comprising 6 taxa of Chlorophyceae; 6 taxa of Bacillariophyceae; 1 taxon of Dinophyceae; 2 taxa of Cyanophyceae and 2 taxa of Euglenophyceae. In February 2015, a total of 18 genera of phytoplankton were also recorded from these lakes. Among the 18 genera, 6 taxa were from Chlorophyceae; 7 taxa were from Bacillariophyceae; 1 taxon was from Cyanophyceae; 1 taxon was from Dinophyceae and 3 taxa were from Euglenophyceae. Chlorophyceae was found to be the dominant group of phytoplankton in the UNIMAS Lakes. Pearson correlation coefficient revealed that chlorophyll a was negatively correlated with dissolved oxygen (DO) and orthophosphate (PO43-). Comparison was made between the physico-chemical parameters of the water in UNIMAS lakes with other lakes in Malaysia such as Putrajaya Lake and Temenggor Lake.
