Tualatin River Basin Water Quality Assessment
In 1990, the Oregon Water Science Center of the
U.S. Geological Survey began a
water-quality assessment of the Tualatin River, in partnership with Clean Water Services .
These web pages are intended to provide an overview of that project,
and to provide selected data from the Tualatin River Basin.

Listen to a podcast (segment #2, episode 11)
describing results from a 2010 report that used stable isotopes of carbon and nitrogen to
identify the sources of organic matter
to Tualatin River bed sediments .
