30-Days of Dissolved Oxygen at the Willamette River at Portland, OR (14211720)

Data are downloaded and processed every 3 hours.
Note that with the Rose Festival fleet coming to town and using sonar, our acoustic velocity sensor that measures water velocity may not work properly. Expect the velocity and streamflow data to be missing until the fleet leaves. We apologize for any inconvenience.

The Willamette River at Portland site is located at the Morrison Bridge in mile downtown Portland, OR. Data are collected every half hour. Periods with no data plotted are plotted as grey areas.

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.

These data are provisional and are subject to revision.
