Submitter does not have a specimen
Seemingly fully grown Nutria, living in the creek and the pond directly in front of Walmart and Verizon in Tigard on SW Dartmouth St.
There is a lot of good information about nutria in Oregon on the Oregon Department of Fish and Wildlife's Living With Wildlife site.
The nutria moves between the two creeks/ ponds in front of the Tigard Walmart. It usually will swim in the water closer to the sidewalk, but recently it has been in the grass near the water in front of the Walmart.
