Abstract
This study examines the differences in bloom formation and water quality between stagnant and flowing aquatic systems. Stagnant water bodies showed heavy algal growth with surface scums, strong odors, low oxygen levels, high turbidity, and poor transparency, conditions driven by nutrient enrichment. These factors promoted the dominance of scum-forming cyanobacteria such as Microcystis, Anabaena, and Dolichospermum. In contrast, flowing waters maintained higher oxygen content, lower nutrient loads, and greater clarity, supporting filamentous cyanobacteria like Oscillatoria and Planktothrix without scum accumulation. The results indicate that stagnant habitats are more prone to eutrophication and harmful algal blooms, while flowing systems remain comparatively stable but still require monitoring. Management efforts should prioritize nutrient control and circulation improvement in stagnant waters, and preventive strategies in flowing systems to maintain ecological health.
