Use the map to identify a site of interest. Holding the mouse over a marker will reveal the site name and ID number. A single click on the marker will pop up additional information about the site as well as links to data and graphs. Alternatively, you can skip this map interface and use the table below the map, or access a non-map version of this page.

Recent and historical data from all USGS Tualatin River Basin water-quality monitors are available through the USGS Data Grapher and Data Tabler utilities. Many, but not all, of the active sites are telemetered and therefore have data available in near real time.

Mouse coordinates:

KEY:	Active monitoring site, Discontinued monitoring site, Active meteorological site
KEY:	Q = flow, S = stage, WT = water temperature, SC = specific conductance, DO = dissolved oxygen, pH = pH, Tbdy = turbidity, Chl = chlorophyll, AT = air temperature, BP = barometric pressure
