Summary

USGS met with 13 local groups and organizations around the Portland, Oregon region to collect information regarding the locations of beaver dams in the Tualatin Basin. The local sources had identified beaver dams between 2013 and 2016, and data were compiled by USGS into an ArcGIS shapefile. Often, the local groups did not know the GPS coordinates of beaver dams, but they had identified beaver-affected reaches during that same time period. Therefore, a second shapefile was created to include the locations of beaver activity (including beaver chews, lodges, and dams) in the Tualatin Basin. The Beaver Dam Locations ArcGIS shapefile shows the known locations of beaver dams in the Tualatin Basin. The Beaver Activity Locations ArcGIS [...]

Purpose

The beaver dam location information was collected and compiled by the U.S. Geological Survey (USGS) for multiple reasons: 1) There is not a current inventory of beaver dams and activity in the Tualatin River basin. This dataset helps fill that gap. 2) This dam inventory will help the USGS validate a model of potential dam capacity in the basin. 3) Many agencies and local non-profit organizations are currently studying beavers, and completing this inventory increased communication and collaboration between groups.
