Matt, thanks for your submission of the nutria report. The animal you saw was in fact a nutria; the thin rat-like tail, webbed hind feet, and white whiskers are all distinguishing characteristics of this species. Nutria are now common in wetlands throughout the Portland Metro area, so you may see more nutria in the future.

If you would like more information on nutria, please visit the nutria page on the Center for Lakes and Reservoirs website at http://www.clr.pdx.edu/projects/ans/nutria.php. Also, I have listed Trevor Sheffels contact information below should you have further questions.
