Abstract Urban stormwater ponds (SWPs) are engineered ecosystems designed to prevent flooding and protect downstream by retaining nutrients associated with runoff, including nitrogen (N). Despite these expectations, multiple studies have found that SWPs low N removal efficiencies can be sources of ecosystems. To understand mechanisms controlling the fate in SWPs, we quantified dinitrogen (N 2 ) gas saturation characterize net exchange as either denitrification or N-fixation. We assessed temporal spatial patterns dynamics fifteen six naturally occurring undisturbed watersheds (Florida, USA) sampling two seasons (dry wet) from depths water column. Samples were equally likely exhibit supersaturation (net denitrification; 50%) undersaturation N-fixation; 50%). In contrast, majority (82%) samples natural supersaturated , indicating denitrification. The mean SWP air–water flux was − 1.7 μg -N m −2 h −1 (range 500 433 ), which lower than clear (40 ; range 68 74 humic (202 41 407 despite considerably higher variation SWPs. These results indicate may part due N-fixation adding new system. Overall, this study shows less effective at removing reactive environment, potentially impacting quality.
