The Fernhill Wetlands outfall discharges to the Tualatin River downstream of Fern Hill Road at river mile 55.2. Data are collected on the half hour. Periods with no data are plotted as grey areas.

Data in the graph are plotted against the axis of the same color. Percent saturation is estimated as a function of water temperature at this site and barometric pressure at a nearby site.

These data are provisional and are subject to revision.
