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

Data are downloaded and processed nearly every hour.

These data are provided by USGS and Clean Water Services. Water-quality data are collected on the half hour and gage height every 15 minutes. Periods with no data are plotted as grey areas. Recent data are provisional and subject to revision.

Streamflow

Streamflow data will be produced once a good rating curve is available.

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.
