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.

Three papers were published in 2014 to document the sources and transport of organic matter in Fanno Creek. Read them at:
  http://dx.doi.org/10.1016/j.jhydrol.2014.06.054,
  http://dx.doi.org/10.1016/j.jhydrol.2014.07.027, and
  http://dx.doi.org/10.1016/j.jhydrol.2014.07.033.

Read an annotated bibliography of published research results in the Tualatin River basin over the last 20+ years. These historical studies are being used to better understand Tualatin River ecosystems and prioritize future data collection and research activities as well as potential management strategies.
