Plankton is the primary food source for aquatic animals so that these herbs have an important role for the aquatic ecosystem. Research conducted in April 2019 at Cimanuk River, Garut, West Java. Water quality is strongly influenced by the activity of sand mining, industrial waste, agricultural, and household waste so that quality is reduced. Water quality can be determined through the study of biological analysis with the use of bioindicators. Bio-indicators used is the aquatic biota phytoplankton. This research uses descriptive research with correlation method. The goal is to determine the relationship between the distribution of phytoplankton with the quality of its waters. From the results of the research produced distribution of phytoplankton that consist of: The abundance of phytoplankton (1,077-a trough hit-1710 individuals/l), the index of diversity (2,6014-2,9184), the index of evenness (0,8651-0,8797), and index of dominance (0,8912-0.9255 level). Based on the person correlation showed that the relationship between water quality (light intensity, brightness, current speed, wind speed) with the distribution of phytoplankton.
