Xuanhuong Lake is considered the heart of Dalat. In this study, algal abundance and diversity in Xuanhuong Lake were studied. Water samples were collected from four different sampling sites from September 2012 to January 2013. The identified species were 75 species belonging to 13 orders, 8 classes, 5 phyla (Cyanophyta, Chlorophyta, Bacillatoriophyta, Euglenophyta, Pyrrhophyta). Chlorophyta has the most species with 33 species (44%), the next was Bacillatoriophyta with 18 species (24%), Cyanophyta with 12 species (16%), Euglenophyta with 11 species (15%), and the least was Pyrrophyta: 1 species (1%). There has also been bioindicator species including Euglena viridis, Euglena acus, and Synedra ulna. Therefore, Xuanhuong Lake is considered mesosaprobic.
