The findings underscore the significant risks posed by cyanobacterial blooms, which can degrade water quality, harm aquatic ecosystems, and pose health risks to humans and animals. Elevated nutrient levels, particularly during summer, create favorable conditions for algal growth, increasing the likelihood of eutrophication. The study highlights the importance of managing water diversion flow rates to minimize nutrient influx and mitigate bloom severity. Without proper intervention, urban water systems may face persistent water quality issues, impacting local communities and ecosystems.
