Thank you for submitting the report. Unfortunately, nutria are are now common in urban wetlands around the region, and I have received previous reports from this location.

It is important to realize that nutria are rodents and potential reservoirs for a variety of diseases that can be transferred to other species, including humans in some cases. As is the case with many species of wildlife, nutria can become aggressive if they are disturbed; it is important to leave them alone.

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.
