Abstract Stormwater wet detention ponds (hereafter “detention ponds”) are implemented to mitigate impacts of urban stormwater runoff on downstream waterbodies. We evaluated the effectiveness of detention ponds in providing this protection by quantifying hydrological, chemical, and biological responses in urban depressional wetlands with and without detention ponds draining into them and comparing these responses to non-urban reference depressional wetlands. We predicted if detention ponds protect waterbodies, then the hydrology, water and soil chemistry, and plant communities of urban depressional wetlands receiving detention pond drainage should be more similar to non-urban depressional wetlands than urban depressional wetlands not receiving detention pond drainage. We found wetlands receiving detention pond drainage had post-storm water level recession rates that were slower than wetlands not receiving detention pond drainage, but faster than non-urban wetlands. We also found wetlands with and without detention ponds draining into them (i.e., urban wetlands) to be more similar to each other regarding water and soil chemistry and vegetation than to non-urban wetlands. Compared to non-urban wetlands, both urban wetland types had elevated pH, inorganic nitrogen, and total phosphorus in their soils and waters, and greater coverage and species richness of disturbance-adapted native and nonnative plant species of lower conservation value. Differences in plant communities were related to changes in hydrology and water and soil chemistry, suggesting detention ponds need to better mitigate the effects of urbanization on these factors. Our findings reveal the need to improve detention pond efficiency and/or identify alternative strategies for protecting waterbodies from the effects of urbanization.
