30-Days of Data from the Tualatin River at Highway 219 (14206241)

These data are provided by the Jackson Bottom Wetlands Preserve. Data are collected on the hour. Periods with no data are plotted as grey areas. Recent data are provisional and subject to revision.

Streamflow, estimated

During periods of high water, discharge data may not be available because the water depth may exceed the range of the rating curve. Streamflow data are considered as estimated for this site because a relatively old rating curve from the Oregon Water Resources Department is being used.

Dissolved Oxygen

In 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.

Oxygen Percent Saturation

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.

Turbidity

Turbidity data are measured in FNU units.

Total Chlorophyll

Provisional chlorophyll concentrations are derived from sensor fluorescence data, and have not yet been checked against lab-derived water-sample chlorophyll results.

Phycocyanin

Phycocyanin concentrations are derived from sensor fluorescence data, and at this time are estimates only.
