Summary

This ArcGIS shapefile shows the known locations of beaver dams in the Tualatin Basin. The dam location information was generated by multiple local agencies, groups, and organizations. The local sources had identified the beaver dams between 2011 and 2019. USGS worked with these local sources to combine all data into one inventory.

Purpose

The beaver dam location information was collected and compiled by the U.S. Geological Survey (USGS) for multiple reasons: 1) Version 1 was the first inventory of beaver dams and activity in the Tualatin River basin. Version 2 includes more dam information (including dam locations along Johnson Creek) and is an update to that dataset. 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.
