Summary

Agricultural watersheds of the Midwest typically export nitrogen (N) and phosphorus (P) to surface waters causing contamination of drinking water reservoirs and, ultimately, hypoxia in the Gulf of Mexico. Two agricultural runoff wetlands, W1 (area 0.16 ha, volume 660 m3) and W2 (area 0.4 ha, volume 1780 m3), intercepting surface and tile drainage in the Lake Bloomington, Illinois, watershed were constructed in 1996 on forest soils (alfisols) between upland cropland and Lake Bloomington. They were created to determine whether wetlands could reduce agricultural nonpoint source pollution before it entered the Lake Bloomington drinking water reservoir. Water (precipitation, tile inflow, surface inflow, outflow, seepage and evaporation) [...]
