30-Days of Data at River Mile 24.5 of Tualatin River (14206694)

Data are downloaded and processed every 6 hours.

This monitor is located in the Tualatin River at river mile 24.5. Data are collected on the hour. Periods with no data are plotted as grey areas. These data are provisional and are subject to revision.

Dissolved Oxygen

In the graph below, "Hourly data" are the raw data, "No supersat." are the hourly data with a ceiling of 100% saturation, "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 and barometric pressure at this site.
