Thank you for submitting the report. Unfortunately nutria are common throughout the Portland metro area, including Fanno Creek. It is important to realize that nutria are potential reservoirs for a variety of diseases that can be transmitted to other species, including humans in some cases. Nutria can also become aggressive on occasion, so please encourage people not to feed the nutria if you ever observe that activity.

The nutria page on the Center for Lakes and Reservoirs website at http://www.clr.pdx.edu/projects/ans/nutria.php contains more information on nutria impacts if you are interested. My contact information can also be found on this site if you have questions or would like further information.

Thanks again for your efforts!
