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 (formerly Unified Sewerage Agency of Washington County, Oregon). These web pages are intended to provide an overview of that project, and to provide selected data from the Tualatin River Basin.
