Abstract

Groundwater enters the wetlands as springflow and as leakage upward through the organic wetland soils. Inflow was composed of direct precipitation (7%), surface water inflow (4%), and groundwater inflow (89%). Outflow from the wetland was composed of streamflow (92%) and evapotranspiration (8%). Some groundwater flowed beneath the wetland but did not discharge within the study area. Groundwater inflow contained 95% of the nitrogen that entered the wetland, precipitation contained 2%, and surfacewater inflow contained 3%. Sixty-six percent of the phosphorus input was from groundwater, 31% from surface water, and 3% from precipitation. The wetland retained 21% of the nitrogen and 7% of the sediment that entered it.
