Limnology is the study of the aquatic system. The current research focuses on the physical, chemical, and biological properties of Bomani beel and Garjan beel in the Kampur district. The study looked into the existence of phytoplankton and compared it to two different beels. The community of plankton changes the water quality based on the parameters. The study looked at 12 water quality characteristics, as well as algae weight analysis and statistical analysis. There are no significant differences in temperature, pH, alkalinity, hardness, turbidity, or other chemical properties. The chlorophyll-a varies significantly; for example, in the winter, the Bomani beel has 10.232 and the Garjan beel has 7.312. Both beels have a Mesotrophic trophic state index. As a result, it is critical to raise public awareness and develop policy strategies for the conservation of these natural resources.
