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 the Oswego Dam site.
