14-Days of Data at the Fernhill Wetlands Outfall (453016123052400)Site has been discontinued. 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. These data are provisional and are subject to revision. Water Temperature, Pre-AerationGraph updated: Friday - Nov 20, 2020 at 16:00:59 EST Water Temperature, Post-AerationGraph updated: Friday - Nov 20, 2020 at 16:00:58 EST Comparison of Pre- and Post-Aeration Water TemperatureGraph updated: Friday - Nov 20, 2020 at 16:00:53 EST Specific ConductanceGraph updated: Friday - Nov 20, 2020 at 16:00:54 EST pHGraph updated: Friday - Nov 20, 2020 at 16:00:57 EST Dissolved Oxygen, Pre-AerationIn the graph below, "Data" are the raw data, "No supersat." are the half-hourly data with a ceiling of 100% saturation, "7-day mean" represents the 7-day running average with no credit for supersaturation, "7-day mean min" represents the 7-day running average of daily minima with no credit for supersaturation, and "30-day mean" is the 30-day running average with no credit for supersaturation. The red line will often plot on top of the black one. If the 7-day or 30-day lines are not plotted, it is due to missing data in that period. "Saturation" represents the 100% saturation value for dissolved oxygen.

Graph updated: Friday - Nov 20, 2020 at 16:00:55 EST Comparison of Pre- and Post-Aeration Dissolved OxygenData in the graph are plotted against the axis of the same color. Graph updated: Friday - Nov 20, 2020 at 16:00:51 EST Oxygen Percent Saturation, Pre-AerationData 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. Graph updated: Friday - Nov 20, 2020 at 16:00:56 EST Oxygen Percent Saturation, Post-AerationData 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.

Graph updated: Friday - Nov 20, 2020 at 16:00:52 EST TurbidityTurbidity data are measured in FNU units. Graph updated: Friday - Nov 20, 2020 at 16:00:59 EST Total ChlorophyllProvisional chlorophyll concentrations are derived from sensor fluorescence data, and have not yet been checked against lab-derived water-sample chlorophyll results. Graph updated: Friday - Nov 20, 2020 at 16:00:51 EST PhycocyaninPhycocyanin concentrations are derived from sensor fluorescence data, and at this time are estimates only.
