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

Data are downloaded and processed nearly every hour.
The chlorophyll and phycocyanin sensors have been removed from this site.

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

The water-level sensor is temporarily down. No streamflow data are available.

Gage Height

The water-level sensor is temporarily down. No gage height data are 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.
