Key factors affecting nutrient levels and algae growth in stormwater ponds

Nutrient-algae response relationships, primarily measured by chlorophyll-a concentration, help predict algal blooms and lake eutrophication. Key drivers of algal biomass include nitrogen (TN) and phosphorus (TP). While regression models have successfully predicted algal blooms in natural lakes using TN, TP and chlorophyll-a concentrations, the nutrient-response dynamics in stormwater ponds differ significantly due to additional influencing variables.
