14-Days of Data at the Oswego Diversion Dam (14207200)

Data are downloaded and processed every 6 hours.

The Oswego Diversion Dam is located in the Tualatin River at river mile 3.4. 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.

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 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.
