The survey method was applied in this research where the West waters of Dumai is the research area, sampling location were set up purposively which divided into 5 stations. Each station has one sampling point with three repetitions. The results of this research found that the distribution of chlorophyll-a in West Dumai  was not evenly distributed. The highest chlorophyll-a concentration was in the 2018 around settlements because of the nutrient runoff from land. The lowest concentration is found in 2016 because of the dry season that exist throughout 2016.Key words: Chlorophyll-a, West Waters of Dumai, Phytoplankton.
