Tualatin Beaver Study


Overview

Beavers and their dams are common sights along creeks in Washington County. Beaver activity can create diverse habitats and homes for many animals, including birds, fishes, and dragonflies. The U.S. Geological Survey (USGS) and Clean Water Services are studying beaver dams and ponds in the county to understand how they affect the amount and quality of water in urban streams. Insights from the study will highlight the effects and benefits associated with beaver dams and ponds in urban streams so that agencies in Washington County can make strategic management and habitat restoration decisions based on science.

This study focuses on urban streams in the lower Tualatin River Basin on the west side of the Portland, Oregon, metropolitan area. The study is conducted in collaboration with Clean Water Services and aims to assess current and potential beaver dam distributions in the basin and quantify the effects of beaver dams and ponds (e.g., hydrology, surface water and groundwater interactions, water quality, and geomorphology).
