This study investigated the diversity of freshwater macroinvertebrates in Kaeng Krachan Dam as a means of assessing the dam's water quality. To investigate the influence of water quality on aquatic insect diversity and abundance, we collected freshwater macroinvertebrates from five stations in Kaeng Krachan Dam, Phetchaburi Province. These stations represented contrasting environments: three stations (S1) in resort areas with continuous water flow and minimal waste accumulation, and three stations (S2, S3, S4) with high human activity. As we move downstream, the concentration of waste gradually decreases. This is because points S4 and S5 are separated by a dilution zone, where pollutants naturally disperse and the water becomes cleaner. Consequently, S5 exhibits lower levels of waste compared to S4.
