This study is on physical water quality data with regards to algal bloom occurrence in a shallow eutrophic reservoir in Malaysia. Some of the important physical parameters emphasized for future remedial studies for the Semberong Dam, a tropical reservoir, are dissolved oxygen, temperature and light intensity. The use of Planktothrix culture as a dominant algae or a mixed culture with a spike of this dominant algae is suggested for remedial study. Other in?uencing factors for consideration are food-web interaction such as in?uence of macrophytes; metereological mainly climatic features, wind-?ows and rainfall; as well as hydrological factors such as water in?ows, lake size and depth, catchment area apart from human and agricultural activities effecting algal bloom formation.
