Global climate change is increasing the frequency, intensity and duration of storms and floodings in the Southeastern United States. Stormwater ponds (SWPs) are one of the most common approaches for managing stormwater runoff in Florida, where there are more than 76,000 SWPs. These engineered ecosystems are built and managed to protect downstream aquatic ecosystems from nutrient loadings from the surrounding landscape. The influence of hydroclimatic and anthropogenic drivers on biogeochemical cycling of carbon (C), nitrogen (N) and phosphorus (P) in SWPs is still poorly understood. We sampled 19 SWPs in two master-planned residential communities in central and southwest Florida monthly from January to November 2024 to assess the quantity and quality (sources, compositions and reactivity) of dissolved organic matter (DOM) as well as the concentrations of dissolved inorganic and organic nitrogen and phosphorus. We found high algal and microbial-derived DOM with low molecular weight but high bioreactivity and more soluble reactive phosphorus in the central Florida SWPs. These chemical characteristics were best predicted by pond size, surrounding road density, water temperature and dissolved oxygen. In contrast, southwest Florida SWPs had more terrestrially-derived humic-like DOM with high photodegradability and higher N concentrations. Southwest Florida SWPs chemistry was positively correlated with specific conductance, house density and property values. We did not observe seasonal variations in DOM or nutrients between dry and wet months across two communities. A significant decline in DOC concentration and algal-derived DOM components was found through August to October in southwest Florida SWPs, which could be associated with a suite of consecutive algae treatments. These results suggest that management practices are more important than hydroclimatic influences for water quality in SWPs. Collectively, this study can help future management decision-making and improve our understanding of global carbon and nutrient cycling from small but ubiquitous artificial aquatic ecosystems.
