Tualatin River Watershed Atlas Maps

In 2001, the Tualatin River Watershed Council produced a Tualatin River Watershed Atlas.  The maps that are listed below are from the atlas.  Pacific University students working with Dr. Bob Van Dyk produced an interactive guide to the Tualatin River Watershed, called the Water CD.  The Council has a number of Water CDs and can make these available.  

These pages show relatively low-resolution images of the maps. Some of the maps also have a link to download PDF files, however these are fairly large (±1 MB). Your browser will most likely be able to display the maps with its built-in PDF player, but if you have problems, visit the Adobe website and download the free player.

If you have a question about any location within the Tualatin Basin and can't find the information you need in these maps, feel free to contact us (contact info below)—we are happy to help you!

NOTE: in some cases, the low-resolution image on the web page is not identical to the image in the PDF file; they represent the same information, but have less detail.
